Why Do I Have Spiders in My House?

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

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 a spider gets inside the home, they lay eggs, which can lead to a large infestation. Sealing up these entry points is key in controlling spider infestation.

Dark, cluttered, and unused rooms are another popular place to find spiders. These are areas that allow them to freely spin their webs and live without any human interruption. If you have one of these rooms in your home, such as the attic, it is important to keep it clean and tidy and refrain from piling up items on the floor. By doing so, it will make your home less appealing for them to stay.

Lastly, it may be difficult to keep your home clean at all times, but this is an important task to keep spiders and bugs away. Spiders are attracted to dirt and dust and places like under the couch, on top of fans, high up in the corners, and under other pieces of furniture. Continuing to mop, dust, and clean up spills/crumbs quickly can help to eliminate the chance of spider infestation.

Signs of 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 can 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 a lot of 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 as spiders will start to make webs and be drawn to interior light.

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

Spider Extermination Costs by Type of Treatment

Labor for spider infestation always begins with an inspection. The trained professional will inspect the area, determine the cause of the infestation, and then determine 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 and 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 of the materials and labor fees.

There are two types of treatments for spiders:

Preventative treatment is beneficial in controlling the problem before it even begins. A licensed professional will come out on a scheduled basis and treat your home with substances that keep spiders from infesting your home. Preventative measures can help to put your mind at ease and prevent any damage that could occur if spiders did infest your home. Preventative treatment typically involves many visits and can range in price from $300-$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 begin by conducting an inspection to determine the infested areas of your home. The exterminator will then use substances to treat the area to get rid of the spiders. Reactive treatments can range in price from $150-$250 depending on the size of the property and the frequency of visits.

Treatment typeCost
Preventative treatment$300-$500
Reactive treatment$150-$250

One Time vs Recurring Control Treatment

When an infestation becomes present, it is important to recognize whether you will 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 that live in a climate prone to spiders or who have had a previous history of infestation, ongoing treatment (monthly, quarterly, etc.) will help to control these pests and prevent infestations indefinitely.

Costs vary between one-time pest control visits vs. 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 of the infestation (or risk of infestation). The chart below illustrates the average cost for spider infestation treatments which can vary again depending on the size of your property and level of infestation.

Duration of treatmentAverage cost (per project)
Initial treatment$150-$250
One time treatment$275-$500
Monthly treatments$50-$60
Semi-monthly treatments$60-$70
Quarterly treatments$125-$300

Threats of Spider Infestation

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 issues such as contamination of food in the kitchen or pantry, severe health issues such as extreme pain, respiratory issues, and necrosis due to bites, as well as other pest infestations.

As spiders move about your home, they do pose a threat to your food and pantry supply. Spiders love food and 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 some of 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, it is extremely important that you contact a qualified exterminator as soon as possible. If left untreated, you are putting yourself, guests, and your pets at risk for health issues.

Signs of spiders in your home is a sign of other pest infestation. Spiders typically eat other pests such as flies, ants, moths, beetles, etc. which can also be a dangerous threat to one’s health. It is important to contact an exterminator to inspect your house for not only spider infestation, but other pest infestations too.

How to Get Rid of Spiders in My Home

Spiders are one of the most commonly feared pests and can be a nuisance to have in and around your home. There are some common methods used to help effectively get rid of these spiders in your home. These methods include:

  • Spider traps: 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. If you have too many spiders for spider traps to be effective, then it is time to call a spider exterminator to help with the problem.
  • Spider sprays: spider sprays are another effective treatment for spider infestation that can kill 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 tends to leave a residue.
  • Natural spider repellent: natural spider repellent is a non-toxic, natural way of removing spiders. Natural remedies such as vinegar, essential oils, herbs, etc. are used to create a repellent that will try to remove spiders from your home. These remedies tend to have a higher cost than other methods and require more frequent applications

How to Get Rid of Spiders on an Outside Deck

Many spiders prefer to hide out in undisturbed, dark places such as the corners of a deck or patio. Out of all pests, spiders are one of the most troublesome to get rid of as they hide out in any nook or cranny they see. Luckily, there are many different methods to get rid of these spiders on your outdoor deck including web eliminators, aerosol sprays, spider repellents, and contact sprays.

Spider repellent$15-$30
Contact sprays$15-$30
Web eliminators$20-$40

Aerosol Sprays

Aerosol sprays provide a rapid knockdown of spiders. The spray can be used as a direct application, in cracks or crevices, or as a broad treatment. Aerosol sprays have an extended killing power on not only spiders, but they also work on other pests.

Spider Repellent

Spider repellents are a non-toxic way of killing spiders. Natural remedies are used to create a mixture that is offensive to spiders, thus keeping them away from the house. These products also help to repel a spider’s prey, which forces them to leave the area and attract their prey elsewhere.

Contact Sprays

Contact sprays are another method for the treatment of spiders on the deck, however, you have to spray on contact in order to kill them. This may not be the most effective method as spiders tend to make their webs in crevices and cracks that you might not see or have access to.

Web Eliminators

Web eliminators offer long-lasting repellency against new cobwebs. It is easy to use and works immediately offering residual effectiveness. This product can be sprayed directly onto a brick, wood, or painted deck surfaces and stops web formation and keeps spiders from coming back.

How to Get Rid of Spiders in the Basement

Basements are locations in the home that allow for particularly easy access for spiders due to them being underground. Spiders tend to migrate to the basement for several reasons, including warmth, privacy, and a great food source. Basements typically do not see a lot of visitors on a given day, which makes it easy for spiders to create their webs and lay eggs without being interrupted. For basement spider infestations, exterminators will use a reactive treatment. This treatment often involves the use of 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. The average cost for an exterminator to remove spiders from your basement ranges from $200-$350, depending on the size of the space and the type of pest control products needed.

How to Get Rid of Spiders in the Attic

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 a tedious job 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 have to schedule further visits for more treatments. The average cost for an exterminator to remove spiders from your attic ranges between $200 and $400, depending on the size of the attic, the difficulty, and the type of pest control products needed.

Types of Spiders

There are many different types of spiders, some found inside the home and some found outside the home.

Common House 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. Some of the most common indoor spiders include the daddy-long-legs, American house spider, cobweb spider, black widow, brown recluse, and yellow sac spider. Hiring an exterminator is the best way to get rid of spiders in your home. They will inspect the inside of your home and create a treatment plan that is specific to your situation.

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, but 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 by using flushing treatments and insecticidal sprays.

Brown Recluse Exterminator Cost

Just as their name states, brown recluse spiders tend to hide out 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. If bitten, it can cause a large wound and can lead to health issues such as necrosis. Once brown recluse spiders are settled, they become very difficult to control and increase their numbers in a short period of time. The best method for removal of 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. The average cost for a brown recluse exterminator is $300-$500 for the initial treatment, depending on the size of your home, treatment needed, and the extent of the infestation. Since brown recluse spiders can be difficult to get rid of, frequent treatments will probably be recommended by the exterminator which will often help to save money in the long run.

What to Do to Prevent Spiders?

Getting rid of spiders entirely may not be realistic, but there are some prevention techniques to make your home uninviting for them.

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. Cleaning often is also very important in preventing spiders from building webs and multiplying in your home. Some of these cleaning preventative 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 and frames, shaking curtains, and picking up clothes off the floor.

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 will help to prevent further infestation.

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

Lastly, there are some outdoor maintenance techniques that can help to 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 where spiders have access to, and keeping plants distanced from your home so that spiders do not access the foundation.

Natural Spider Repellent

Natural spider repellents can do wonders in combating a spider invasion in your home. There are certain natural products that can be used to drive spiders away and kill them on contact including peppermint, vinegar, Diatomaceous Earth, and plants.

Peppermint is a natural remedy with strong evidence as a good spider repellent. Spiders smell with their legs and do not like strong smells and therefore avoid crawling through peppermint-smelling surfaces. A common peppermint mixture includes dish soap, water, and peppermint oil.

Another natural strong-smelling remedy that spiders hate is vinegar. Spiders are sensitive to vinegar’s taste and strong odor. A solution of 50/50 water and vinegar in a spray bottle can be applied to surfaces, cracks, and crevices to keep spiders away.

Diatomaceous Earth is a type of fossil dust that can be of harm to spiders. The dust can be scattered on soil or any other places where spider infestation may occur. When spiders eat it, they dehydrate and die.

Lastly, some plants are another common natural spider repellent. These plants can be planted around the perimeter of your home to help deter spiders from staying around. Some spider repelling plants that can be planted in your garden include lavender, eucalyptus, lemongrass, mint, lemon balm, and lemon verbena.

Additional Considerations and Costs

  • Insecticide dust. Non-repellent insecticide dust can be very useful in spider extermination. The dust helps cling 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 may hide to help get rid of them.

A tip is to ask for references from previous customers and read reviews before choosing the company.
  • DIY. It is possible to remove spiders yourself if you feel up to the job. For spiders, there are many natural remedy solutions that can be created to help exterminate spiders from your home. If you have any doubts, however, contact a professional.
  • Bug bombs for spiders. Bug bombs are aerosol foggers or sprays that kill spiders immediately upon contact and act as a barrier against re-infestation for several months. This is an effective method for spider extermination and as a bonus, it does not leave any residue.
