Spider exterminators are licensed professionals who are skilled in handling spider infestations. These trained professionals have in-depth knowledge about spiders and are well experienced in safely solving spider infestation problems inside and outside your home. Although most may think that dealing with a spider infestation can be easy, many are unaware of the dangers of handling spiders on their own and don’t realize that spider infestations are not that easy to deal with.

The average cost to hire a spider exterminator ranges from $200 to $500, with the average homeowner spending around $275 to hire a spider exterminator for a one time visit to assess the situation, apply pesticide to the perimeter and interior affected areas, including all of the materials and labor fees. Prices can be as high as $800 for spider extermination using targeted spray treatment in a 3,000 sq.ft. home and as low as $100 for general pest control treatment targeting a small spider population in a 2,000 sq.ft. home or smaller.

Spider Extermination Costs by Method

Spiders are one of the most commonly feared pests and can be a nuisance to have in and around your home. Some common methods used by professional exterminators help effectively get rid of these spiders in your home. These methods include spider dust, traps, spray, and fumigation. These services range in cost from $100 to $800, which typically includes the cost of the initial inspection, treatment, and monitoring as well. Sometimes treatments like dust and trap may be used together depending on the infestation.


Cost to Exterminate Spiders Using Dust, Traps, Spray, or Fumigation

Cost to Exterminate Spiders Using Dust, Traps, Spray, or Fumigation


Extermination MethodAverage Cost
Dust$100 - $250
Trap$100 - $300
Spray$200 - $500
Fumigation$300 - $800


Spider Dust

Professional exterminators normally charge around $100 to $250 for an inspection and dust extermination service. Non-repellent insecticide dust can be very useful in spider extermination. The dust clings to webs and is likely to be contacted by the spider when on the web. This dust can be applied to other places where spiders hide to help get rid of them.

Spider Traps

Extermination companies price their spider inspection and trap treatments around $100 to $300. Spider traps are non-toxic and cost-effective glue traps that can be placed in the corners, along the walls, in the basement, and in any other location that spiders have been spotted. Spider traps are most effective for smaller infestations as they only provide so much room to get caught on the trap.

Cost to Spray a House for Spiders

The average cost to spray a house for spiders is $200 to $500. Spider sprays are another effective treatment for spider infestation that kills on contact. The spray can be used under furniture, in closets, along the baseboards, in any cupboard space, and in many other places in the home where needed. The spray is easy to use but can be problematic in homes with small children or pets as it leaves a residue.

Spider Fumigation Cost

Professional spider fumigation costs $300 to $800. Fumigation is the most complex and high-level spider treatment. It takes spraying to the next level. While spot spraying targets specific areas where spiders may be, fumigation applies chemicals that treat the entire room/house, exterminating all pests in the process. Fumigation uses stronger chemicals than spraying.

Spider Extermination Cost by Size of Infestation

The cost of spider extermination is typically determined by the size of the infestation. Removing one or two large spiders from a home is different from exterminating hundreds hiding in nests and crawling all over the walls. The pest control process starts with an inspection, where the exterminator evaluates the situation and determines the best way to treat the infestation. The pest management method is the biggest cost factor. Usually, a large infestation requires more invasive and expensive treatment.


Cost to Exterminate a Small, Medium, Large, or Severe Spider Infestation

Cost to Exterminate a Small, Medium, Large, or Severe Spider Infestation


Size of InfestationAverage Cost
Small$100 - $300
Medium$200 - $400
Large$400 - $600
Severe$500 - $800


Small Spider Infestation

Most pest control companies charge $100 to $300 to treat a small spider infestation. If you notice a few spiders crawling around or a couple of nests, this is considered a small infestation that can usually be taken care of in one treatment. Common extermination methods include web clearing or flushing treatment.

Medium Spider Infestation

Homeowners pay $200 to $400 to exterminate a medium spider infestation. If there are several nests and visible spider eggs, it’s probably a medium-sized spider population. Exterminators will get rid of the nests to stop the infestation from spreading, with insecticidal sprays serving as a common starting point for chemical treatment.

Large Spider Infestation

The average cost of treating a large spider infestation is $400 to $600. Large spider infestations involve more than five nests and visible spiders hanging in their webs or scurrying along the walls. These infestations require a deeper level of chemical treatment to exterminate them fully. Inspections ensure they aren't hiding anywhere else.

Severe Spider Infestation

Treating a severe spider infestation costs anywhere from $500 to $800. Generally, exterminators classify an infestation as severe if there are hundreds of spiders throughout different areas of the home or hidden behind walls or under the floorboards. Severe infestations can pose an immediate risk to residents depending on the species, which is why intense chemical treatment is required to eliminate the spiders and prevent further infestations.

Spider Pest Control Cost by Frequency of Treatment

When an infestation becomes present, it is important to recognize whether you need a one-time treatment or a recurring control treatment. Spiders are a common household pest that can be difficult to control and may need to be treated more than a one-time visit can handle. For people who live in a climate prone to spiders or who have had a previous history of infestation, ongoing treatment (monthly, quarterly, etc.) helps control these pests and prevents infestations indefinitely.

Costs vary between one-time pest control visits and recurring visits. Typically, initial visits cost more than scheduled recurring treatments because there is a lot of work involved for a one-time visit. Frequent maintenance visits are cheaper and can be scheduled monthly, bi-monthly, or quarterly, depending on the extent or risk of the infestation. The chart below illustrates the average cost for spider infestation treatments which vary depending on the size of your property and level of infestation.


Cost of a Monthly, Semi-Monthly, Quarterly, or One-Time Contract to Exterminate Spiders

Cost of a Monthly, Semi-Monthly, Quarterly, or One-Time Contract to Exterminate Spiders

Quarterly$150 - $250
One-Time$275 - $500

Spider Extermination Cost by Location

One of the factors that influence spider extermination cost is the location of the infestation. Like with other common household pests, the harder the pests are to reach, the more professional exterminators may charge for their services. The table below highlights the average prices for getting rid of spiders using a one-time perimeter and interior pesticide treatment. Remember, these prices can vary further depending on the severity of the infestation and the treatment method.

Cost to Exterminate Spiders in Deck, Patio, Carpet, Kitchen, Shed, Lawn, Yard, Bedroom...


LocationAverage Cost
Deck$100 - $300

Kitchen$100 - $350
Shed$150 - $450
Lawn$150 - $500

Bedroom$200 - $500
Basement$200 - $500
Bathroom$200 - $550
Garage$200 - $600
Attic$200 - $600


Spiders on the Deck

Treating spiders on the deck should cost $100 to $300. Many outdoor spider species make their webs underneath the deck railing 1 and posts. If you catch them early enough, a simple vacuum web cleaning treatment may do the trick. If numerous nests are scattered on and underneath the desk, more rigorous outdoor extermination will be required.

Spiders on the Patio

Similar to deck spider treatments, exterminating spiders on the patio usually costs $100 to $300. Wood or concrete patios may have posts, lights, and furniture that attract indoor and outdoor spiders. Patios are low to the ground, so grass spiders and wolf spiders may move toward the patio, especially if other insects are around. Traps or sprays are the most popular patio spider removal methods.

Spiders in the Carpet

A spider infestation in the carpet costs $100 to $325. Professional pest removal companies will determine how many more spiders are hiding in the carpet or on the floorboards and then decide how to remove them. Chemical spray treatment is usually enough to take care of small or medium infestations. If spiders have made multiple nests in the carpeting, it may need to be removed altogether to stop the spiders from coming back.

Spiders in the Kitchen

Getting rid of spiders in the kitchen costs $100 to $350. Indoor spiders are drawn to food scraps and other insects in the kitchen, and it’s not uncommon to find spiders making their webs in the corners of the kitchen or inside the room’s lighting fixtures. For a small kitchen infestation, exterminators will probably use spray or traps, but entire fumigation may be required for a large infestation.

Spiders in the Shed

Professional spider extermination for shed infestations costs $150 to $450. Spiders are drawn to the dark shelter of sheds where many insects may be. Plus, many homeowners only check their sheds every so often, so sometimes they don’t catch indoor or outdoor spiders in the shed until it’s too late. The shed may need to be sprayed to exterminate fully any spiders present in the space.

Spiders in the Lawn

Most homeowners pay $150 to $500 to treat a spider infestation on their lawn. The more webs there are in the grass, the more traps or chemicals required to clear out the spider problem. Lawn mowing and trimming vegetation is a preventative measure that stops spiders from taking over someone’s backyard grass or front garden.

Spiders in the Yard

Pest control companies charge $150 to $550 to treat yard spiders. A yard infestation includes spiders in the lawn and other locations like the garden and surrounding trees. Traps and spray treatment are the most popular pest control plans for removing spiders from these areas. Clearing old vegetation and brush piles can keep spiders from returning to the yard in the future.

Spiders in Bedroom

A bedroom spider infestation treatment costs $200 to $500. Spiders could be found in the corners of the ceiling or flooring, underneath the floorboards, behind walls, and even in the bedroom lights or furniture. Pest professionals use spray treatments and web removal for small spider problems in bedrooms, but a big issue may warrant fumigation of the bedroom and surrounding areas.

Basement Spider Control

The average cost for an exterminator to remove spiders from your basement ranges from $200 to $500, depending on the size of the space and the type of pest control products needed. Basements are locations in the home that allow for easy access for spiders due to them being underground. Spiders migrate to the basement for several reasons, including warmth, privacy, and a great food source. Basements typically do not see many visitors on a given day, making it easy for spiders to create their webs and lay eggs without being interrupted.

For basement spider infestations, exterminators use a reactive treatment. This treatment involves using a pesticide sprayed across key areas in the basement, including ceilings, baseboards, and crawl spaces. Depending on the issue, the exterminator may have to schedule further visits for more treatments.

Spiders in the Bathroom

The average cost for exterminating spiders in the bathroom is $200 to $550. Spiders’ prey is attracted to the moisture and cracks in the bathroom, which can draw spiders into the space too. A small infestation can be handled with a trap or quick spray treatment, while a serious situation involving multiple nests and dangerous spider species may need fumigation instead.

Spiders in the Garage

Eliminating spiders from a garage costs $200 to $600. Wood elements, dark spots, and exposed cracks attract spiders to the garage, not to mention the presence of small insects they prey on. Depending on the design, size, and condition of your garage, it may take more time and labor to find all the hidden spider spots. Spray and fumigation are the usual pest control services for spiders in the garage.

Spiders in the Attic

The average cost for an exterminator to remove spiders from your attic ranges between $200 and $600, depending on the size of the attic, the difficulty, and the type of pest control products needed. Spiders prefer to migrate to dark, quiet, cluttered spaces where they won’t be disturbed, including the attic. Removing spiders from the attic can be tedious as there are many cracks, corners, and crevices that need to be inspected. Hiring an exterminator to remove spiders from the attic involves a thorough inspection of the main area and the use of a pesticide spray to kill them. Depending on the extent of the infestation, the exterminator may schedule further visits for more treatments.

Spider Extermination Cost by Company

The average cost to exterminate spiders for a medium-to-large infestation ranges from $175 to $500, depending on the company. Several pest control companies lead the way in spider extermination, including Terminix, Orkin, and Western Exterminator. The table below shows their average prices, but it varies by location, size of the house, and specific infestation situation. Always check with your extermination company for the most accurate quote for your home.


Cost of Western, Terminix, or Orkin Spider Extermination Services

Cost of Western, Terminix, or Orkin Spider Extermination Services


CompanyAverage Cost

Western Exterminator Spider

Hiring a Western Exterminator costs $175 to $350 for spider treatment. The company provides comprehensive spider management to remove webs via vacuuming and catch spiders to identify how harmful they are. Their spider removal specialists use discreet treatments like insecticidal sprays, flushing, and chemical treatments. They also install invertebrate monitors to trap spiders in areas where they may be seeking shelter, food, or mating partners.

Terminix Spider Cost

Terminix charges $200 to $450 for spider extermination services. The company’s pest specialists inspect the inside and outside of the home to determine the source of the spider infestation and the best treatment method. They have home fumigation and sealing treatments to keep spiders out and are known for catching and treating brown recluse infestations across the central and southern U.S.

Spider Exterminator Cost

The first step towards extermination is always a spider inspection. The trained professional inspects the area, determines the cause of the infestation, and outlines a treatment plan that is best for your situation. If a chemical treatment plan is put in place, chemicals are sprayed on the appropriate areas of the home. They will schedule further visits for more chemical applications. If the treatment plan involves traps or removal, the traps will be set up, and the technician will come back at a scheduled time to remove or relocate them. There may be multiple visits before all of the spiders are removed. Most spider exterminator companies charge on a project basis depending on the type of treatment needed, number of visits, level of infestation, and size of the home. The average cost per project is between $200 and $500, including all materials and labor fees.

When To Call an Exterminator For Spiders

If homeowners only notice one spider, they may wait to call an exterminator. However, this could be a mistake as there are often more spiders hiding behind walls, under furniture, or in hard-to-see nests. It’s always best to call an exterminator if you notice a spider problem, as they can address it quite quickly before there are hundreds or even thousands of spiders taking over the property.

In some cases, spiders are more visible than other household pests, as they can spin large webs in the corners of walls and structural components. Often, you can spot tiny baby spiders on the wall. Other signs of a spider infestation include another pest problem. Spiders are drawn to food and shelter just like other bugs. If there’s a problem with one pest species, there may be spiders involved too. The only way to know for sure what’s going on with spiders and pests at your house is to call in a professional exterminator.

Signs of a Spider Infestation

If you notice any of the following signs in and around your home, there is a high chance that you are experiencing spider infestation, and it should be taken care of right away.

One of the most common signs of spider infestation is if you notice an abundance of webs both inside and outside your home. One or two spider webs are common, but if you start seeing more, then you should be a little bit worried.

Spiders lay hundreds or even thousands of eggs at a time in a single egg sac. If you find egg sacs in your home, it is important to dispose of them right away as this can cause a major infestation of spiders around your home once hatched. If you suspect spider sacs in your home, it is important to call an expert immediately.

Another common sign of spider infestation is if you start to notice several insects around your home. If there are lots of insects, then there is a good chance there will soon be spiders around as they love to eat them. It is extremely important to keep your windows and doors closed. Spiders will start to make webs and be drawn to the interior light.

Finally, simply seeing spiders around your home is a sign of infestation. If you start seeing some, more are sure to be around. If this is the case, it is important to contact a professional right away before the problem worsens.

All About Spiders

Spiders are arthropods with eight legs, fangs for injecting venom, and spinnerets to produce silk. Spiders breathe air and are not insects, despite their typical association with other household bugs. They are found on all continents other than Antarctica and have six to eight eyes to make it easier to catch their prey. Some spiders have incredible jumping or running abilities to make them fierce predators. There are poisonous spiders that humans need to watch out for and others that may not be poisonous but still cause a big nuisance in someone’s house.

What Do Spiders Look Like?

There are upwards of 45,000 spider species worldwide. They range significantly in size and color. Some spiders are hard to see with the naked eye, and others are the size of your hand. The main identifying features of spiders are the two distinct sections of their body--the thorax where their head is and their abdomen. Spiders have eight legs and six or eight eyes. Some are hairy, and others have noticeable patterns to help identify them.

Where Do Spiders Nest?

Spiders may nest inside or outside your home. Some species prefer dark indoor spaces while others like vegetation and wood structures like sheds and garages. They generally look for safe areas like corners where they can be secluded, but they have been known to make their nests on fence posts, inside lights, and inside furniture. Check under window ledges and inside fireplaces as spiders may also nest in these tight spots.

What Do Spider Eggs Look Like?

Spider eggs are round or oblong and are found in large clumps. Spiders can lay hundreds of eggs at one time. White or cream spider egg sacs can have a smooth or rough texture depending on the species. The egg sacs contain silk from the spider. Some spiders have messy egg sacs, while others are clean and tidy. The important part is getting these eggs out of your house as soon as possible to avoid an explosion in the spider population.

Types of Indoor Spiders

A house spider prefers to be indoors in a safe and warm environment. The majority of these spiders cause no harm and are simply predators of pests. While most aren’t harmful, some can be more problematic than others. Hiring an exterminator is the best way to get rid of spiders in your home. They inspect the inside of your home and create a treatment plan specific to your situation.


Comparison of Types of Indoor Spiders: Daddy Long Legs, Domestic House, Black Widow, Yellow Sac, American House, Long Bodied Cellar, Hobo, and Brown Recluse

Comparison of Types of Indoor Spiders: Daddy Long Legs, Domestic House, Black Widow, Yellow Sac, American House, Long Bodied Cellar, Hobo, and Brown Recluse


Daddy Long Legs Pest Control

Daddy long legs grasp their prey with claws near their mouths. They are arachnids with eight legs. Daddy long legs fall under the chelicerae group rather than true spiders (order Araneae). Daddy long legs have a rounded body and one pair of eyes, unlike true spiders with two distinct parts to their body and six to eight eyes. Daddy long legs don’t make silk or weave webs. Instead, they rely on ambush instincts to kill their prey, similar to wolf spiders. General pest control methods work well for daddy long legs, found both inside and outside the home.

Domestic House Spider

The domestic house spider is also referred to as the barn funnel weaver. These spiders make flat webs with a funnel retreat on one side near holes or cracks in the home. They can be up to one inch long, and their legs can span two inches. Getting rid of these spiders is fairly straightforward, as the webs and eggs need to be vacuumed and removed. Exterminators recommend sealing cracks and crevices and eliminating harborage sites and sources of food to stop these spiders from repopulating in your home.

Black Widow Pest Control

Black widows are poisonous and most commonly found in the northeast U.S. They are actually considered beneficial because they feed on so many other insects, but the females can attack when they feel threatened. Black widows have the most toxic and serious spider bites in the U.S., with neurotoxins in the venom that compromise the nervous system. They have a bright red mark on their abdomens to warn off attackers. Professional chemical treatment from licensed pest specialists is the best course of action when dealing with a black widow spider infestation.

Yellow Sac Spider Control

As the name suggests, yellow sac spiders have a light body and black feet. They are active at night and have been known to hide in clothing and gardens and near trees. Sometimes a yellow sac spider bite is mistaken for a brown recluse due to the pain, redness, and swelling. These spiders make silk sacs to lay as many as 50 eggs, so these sacs must be removed as part of the pest control treatment. Vacuuming and chemical treatment can help.

American House Spider

Despite its name, the American house spider is found all over the world. This species lives in furniture, garages, and sheds but is generally not a threat unless they feel attacked. They are usually dirty white or brown with dark markings on their legs and abdomens. The larger females have yellow legs, and the males have orange legs. They make billowy webs similar to Halloween decorations. Pest control treatments usually start by removing these webs. Exterminators may use a chemical treatment to reduce the spider population in your house.

Long Bodied Cellar Spider Control

The long-bodied cellar spider is very similar to and often mistaken for daddy long legs. The difference is that cellar spiders have a noticeable separation between their abdomen and head. The bottom of their body is three times as long as it is wide. Cellar spiders have eight elongated and thin legs as well as eight eyes separated into two lateral groups. These spiders are often found in dark cellar and basement spaces. Pest professionals usually use spray treatment to get rid of them.

Hobo Spider Control

Hobo spiders are most common in the Pacific Northwest. These funnel web spiders thrive both inside and outside the house, although they have earned the nickname of “aggressive house spider” with their running speed of 2.2 MPH. They are light or medium brown with solid legs and stripes/chevron pattern on the head and thorax. They build funnel webs with an opening at both ends, typically near a crack in the wall or floor as their escape route. Hobo spider treatment includes eliminating food sources, sealing cracks, and creating an insect defense barrier, plus spray or fumigation.

Brown Recluse Control

Just as their name states, brown recluse spiders tend to hide in secluded areas of the home, including cracks and crevices, sheds, closets, and crawl spaces. They are known to hide out in boxes where infestation will occur. Brown recluse spiders are well known for their dangerous venom. Once brown recluse spiders are settled, they become very difficult to control and increase their numbers in a short time. The best removal method for brown recluse spiders is a trained spider exterminator. An exterminator will start with a complete inspection of your home’s interior and exterior and determine the best treatment solution for your situation. Since brown recluse spiders can be difficult to get rid of, frequent treatments will probably be recommended by the exterminator, which will help save money in the long run.

Types of Outdoor Spiders

Outdoor spiders prefer the outdoors and will take care of any pests around. They will set up elaborate webs all around the landscape, patio, and deck. Just like indoor spiders, some of the outdoor spiders can be more problematic than others. Most times, they go about minding their own business unless interrupted. Some of the most common outdoor spiders include wolf spiders, orb weavers, grass spiders, and jumping spiders. Exterminators will create a plan to treat the outside of your home by removing spiders, webs, and eggs with flushing treatments and insecticidal sprays.


Comparison of Types of Outdoor Spiders: Jumping Spider, Tarantula, Wolf Spider, Grass Spider, and Orb Weaver Spider

Comparison of Types of Outdoor Spiders: Jumping Spider, Tarantula, Wolf Spider, Grass Spider, and Orb Weaver Spider


Jumping Spider Control

Jumping spiders account for 13% of all spider species and are known to jump and attack their prey. They can jump as much as 25 feet their own height and have extremely fast reflexes. Four of the spider’s eight eyes are higher up on its body for better vision. The two in the center of the face have high resolution. They produce silk retreats rather than complex webs and are fairly dull in color, either black or brown. Vegetation treatment is required to exterminate jumping spiders where they thrive outside.

Tarantula Control

Tarantulas are recognized for their black or brown hairy bodies and strong climbing claws. The tarantula family has the largest spiders in the world. They can often be spotted from farther away as they scurry along the grass or rocks. Tarantulas like desert regions like Arizona, California, and Texas but are also common in Colorado and New Mexico. Glue traps and spray treatment are the most common ways to eliminate tarantulas from your yard.

Wolf Spider Control

Unlike many other species, wolf spiders do not spin webs. Instead, they burrow in holes or seek shelter close to the ground. They rely on their fast running ability to catch prey, pouncing on smaller insects and attacking with sharp horizontal fangs. Wolf spiders have eight eyes in three rows with long, hairy legs and a Union Jack design on their back. They are grayish-brown and feature lighter stripes, ranging from ¼ inch to 2 inches in size. Spider traps and spray treatments are recommended for wolf spiders.

Grass Spider Control

Grass spiders make funnel webs low to the ground to trap their prey. They have a yellowish-brown color and look similar to their cousins, the hobo spider and the domestic house spider. Brush piles and vegetation attract these spiders. Grass spiders are disturbed by lawn maintenance, so frequent lawn mowing is one good way to prevent their populations from moving in. Professional pest management usually involves spray treatment to eliminate grass spiders from a residential property.

Orb Weaver Spiders

Orb weaver spiders are grey or reddish-brown with a pattern and dorsal stripe on their triangular abdomens, which feature two large humps. They feed on insects and rarely bite humans, focusing instead on building flat stick webs with a spiral capture. Sticky traps and physical removal of the webs are good starting points, but for larger orb weaver spider infestations, chemical treatment may be required.

Are Spiders Dangerous?

Although most spiders may not be that harmful, that doesn’t mean that they can’t pose any threats when infesting a home. A spider infestation can cause contamination of food in the kitchen or pantry, severe health issues such as extreme pain, respiratory issues, and necrosis due to bites, and other pest infestations.

As spiders move about your home, they pose a threat to your food and pantry supply. Spiders love food. If they get into it, they can contaminate it with their waste. This can lead to major health risks and bacteria growth if consumed.

Black widows, brown recluse spiders, and wolf spiders are among the most common and dangerous spiders. If bitten, these spiders’ venom can lead to extreme pain, respiratory issues, or even necrosis. If you suspect you have any of these spiders in your home, you must contact a qualified exterminator as soon as possible. If left untreated, you are putting yourself, guests, and pets at risk for health issues.

Signs of spiders in your home may be a sign of other pest infestation. Spiders typically eat other pests such as flies, ants, moths, and beetles, which can also be a dangerous threat to one’s health. It is important to contact an exterminator to inspect your house for spider and other pest infestations.

How to Know if a Spider is Poisonous

Although there are more than 3,000 spider species in North America, there are just two known to be poisonous to humans. The brown recluse and black widow spiders are the ones to watch out for, as their venom carries cytotoxins and neurotoxins. If you can identify these species, then you can know when to call a spider exterminator immediately.

The brown recluse has a violin-shaped mark on its back and is dirty or sandy brown and sometimes yellowish. The spider’s legs are completely uniform in color. If other pigments or strips are on the legs, it’s not a poisonous brown recluse. The black widow has a black body, or a brownish-black for females, with two distinct red triangular markings to create an hourglass shape under the abdomen.

Although most household spiders aren’t poisonous, they still aren’t a great pest to have in your home, which is why it’s so important to have professional assistance from a pest control company. Local exterminators should handle all types of spiders, including the brown recluse or black widow. They can provide more information on the best treatment method for your home after they inspect the situation.

Pet Safe Spider Control

If you have pets in your home, you can talk to your pest control company about pet-safe treatments. Not all extermination chemicals are safe for pets, so if they use spider dust, spray, or fumigation treatments, you should confirm whether there are any risks to your family’s animals. Most pest control companies offer some form of pet-safe treatment, but it’s always best to check with your local providers. Sometimes their standard treatments are already pet-safe, but others may charge $50 to $100 more to use special chemicals that harm only pests, not household animals.

How to Prevent Spiders

Spiders are one of the most feared and disliked types of insects. Although most are harmless, they still cause panic in those who come in contact with them. They are generally unwelcome in any home. Effective spider control begins with understanding what causes a spider infestation and what you can do to protect yourself from them entering your home.

One of the most important preventative techniques is to declutter and keep your home clean. Spiders tend to cluster in dark places where they’re not likely to be interrupted, such as storage boxes, piles of newspapers, and crammed closets. Keeping these areas organized will help to prevent spiders from accessing these spots and ensure a spider-proof house. Cleaning often is very important in preventing spiders from building webs and multiplying in your home. Some of these preventative cleaning techniques include ensuring there are no pieces of food on your floors, removing dust and dirt in the corners of rooms, sweeping or vacuuming regularly, cleaning window sills 2 and frames, shaking curtains, and picking up clothes off the floor.

A very common cause of spider infestation is easy entry points, including unsealed cracks, loose vents, gaps in the doors, and any crevices in the walls of your home. Once spiders get inside the home, they lay eggs, leading to a large infestation. Sealing up entry points is key in controlling spider infestation.

Removing existing spider webs inside your home is another preventative technique in combating spider infestation. If you notice any cobwebs up in the corners, windows, baseboards, or anywhere in your home, use a cloth or a vacuum to get rid of them. This helps to prevent further infestation.

Homemade spider sprays are another method of preventing spiders from entering your home. Spiders do not like peppermint or vinegar. A mixture of these two ingredients makes a good preventative spray. Using this in closets, on doors and window sills, baseboards, and other common spider locations can be very beneficial.

Finally, some outdoor maintenance techniques help prevent spiders from entering your home. Some of these techniques include keeping windows and doors to the outside closed as much as possible, turning off the outside lights at night to prevent spiders from attracting to the other bugs, filling gaps and cracks outside your home, and keeping plants distanced from your home so that spiders do not access the foundation.


Spider Extermination in Protective Suits


Reactive vs Preventative Spider Treatment

Depending on your situation and the extent of the problem, the professional will recommend either a reactive or preventative treatment.

Preventative treatment is beneficial in controlling the problem before it begins. A licensed professional will come out regularly and treat your home with substances that keep spiders from infesting your home. Preventative measures help put your mind at ease and prevent any damage that could occur if spiders infest your home. Preventative treatment typically involves many visits and ranges in price from $150 to $500 depending on the size of the property and the frequency of visits.

A reactive treatment involves treating a spider infestation that is already present. A licensed professional will come out and conduct an inspection to determine the infested areas of your home. The exterminator will use substances to treat the area to get rid of the spiders. Reactive treatments range in price from $300 to $600 depending on the size of the property and the frequency of visits.

Enhancement and Improvement Costs

Cleaning Services

You may want to consider hiring a house cleaning service that can help keep your home clean and help with preventing spider infestation. House cleaning services average $75 to $125 per visit for a 2,000 sq.ft. home. The cost depends on various factors, including the size of the home, how many rooms, level of dirtiness, and flooring materials.

Home Repairs

Sometimes repairs are needed after the pest is gone. If walls need to be opened to reach the pest, or if the pest damaged your property during its stay, you may need repairs. This can have a range of associated costs depending on the pest. The cost of repairs ranges from $150 to $500.

Additional Considerations and Costs

  • Repellers. Spider repellers can be an effective barrier for keeping spiders away and for peace of mind. Spider repellers come in many different forms, including pouches, automatic sprays, dusting powders, liquids, plugins, and spot treatments. Spider repellers range from $13 to $15 per repeller, depending on the form, size, and brand. Certain natural products can drive spiders away and kill them on contact, including peppermint, vinegar, Diatomaceous Earth, and plants.
  • Spider and ant extermination. Pest exterminators often deal with pests jointly, so they treat the entire house for pest populations, including ants and spiders. Spraying for spiders and ants can be done at the same time and costs $200 to $400, as the chemicals target both pests in the home, effectively eliminating them. Exterminators may also fumigate these populations in a room or area of the house, depending on the level of infestation.
  • Coverage period. Professionals should give you answers on how long their treatment will last and give a time estimate for a coverage period.
  • Guarantee. Many companies offer you a guarantee in the removal of spiders from your home. If unsuccessful, most companies offer you a 100% money-back guarantee or will continue with free treatments. It is important to discuss the company's guarantee before hiring them.
  • Certification. All trained professionals that apply pesticides have to complete an exam to obtain a pesticide exterminator license.
  • Hiring tips. It is important to select a company that has many years of experience in dealing with spider control. It is good to receive quotes from many companies before selecting the one to use to make sure you are getting a fair price. A tip is to ask for references from previous customers and read reviews before choosing the company.
  • DIY. While some homeowners may try to remove a spider nest themselves, this is not recommended. Spiders are challenging to eliminate. Where there’s one spider, there’s probably more hiding somewhere else. DIY spider removal can be dangerous if the spider is poisonous. Most of the time, it takes a professional to determine what species of spider it is. Professional pest management is always preferred.
