​

Medium Ant Infestation

A medium ant infestation is an infestation with a growing colony of ants. More ants are roaming around, and you can notice some frass on cracks. A medium ant infestation could cost you about $350 for treatment areas under 3,500 square feet using baits or pesticides.

All About Ants

Ants are a common pest that can be found in numerous homes and buildings - even those that are clean and sanitary. They are typically found near sources of food. For the majority of the ants, you’ll find indoors, this means on counters, on the floor beneath tables and chairs, inside cabinets, and anywhere food crumbs may typically be dropped.

Carpenter ants may also be found inside your window casings, baseboards, attic, and any other areas where there is both abundant wood and easy access from the outdoors. Outdoor ants usually build a mound in the field or your yard.

There are worker ants and reproductive ants in a colony. Reproductive ants include the queen and male ants. It is usually hard to spot the queen as it stays in the nest for most of the time. The worker ants are the ones that cause nuisance and damage as they look for food and build the colony nest.

Are Ants Dangerous

Ants are attracted by things such as warmth, food particles, and in the case of carpenter ants, even your home’s structure. Any ant can bite, and while they don’t carry diseases, they can contaminate food, and, according to the CDC, some species of fire ant can be dangerous for young children and the elderly. Those with health issues as their stings can be painful or cause negative reactions. Ants can also impact your garden, decrease the amount of wildlife nearby, and in the case of carpenter ants may even do severe damage to your home.

Odorous ants will affect the scent of your home when they infest the surrounding area and especially inside it. They will excrete a nasty odor when they are threatened or crushed. Furthermore, odorous ants infest food and contaminate it. They carry harmful bacteria such as salmonella and more. According to the University of California, these bacteria can be transferred through food or an open wound to humans through certain species of ants. However, the risk is relatively low, with the exception of ants found in developing countries.

Can Ants Damage Your Home?

Ants can cause damage to your home. The type of damage usually depends on the type of ant. However, nuisance is a common factor for all ants in your home. For example, pavement ants have sheer numbers and crawl onto food, counters, and other common areas in our home.

Pavement and carpenter ants prefer to stay outside and are less likely to infest food compared to odorous ants. However, carpenter ants do cause structural damage to your home—the tunnel through wood to establish their nests. Carpenter ants prefer cool areas and decaying wood. You can find them in bathrooms, under kitchen sinks and other areas. They can cause major structural damage to your home, but that will take years.

Signs of Ant Infestation

There are multiple signs of ant infestation. The most basic sign is sighting worker ants in your house. They could be on the sink looking for water, in the garbage, pantry, or on dirty dishes looking for food.

However, ants sighting also depends on the time of day and season. In warm weather like summer, the ants are most active after dark. Ants are inactive in cool weather except when they nest in a heated part of the house. In spring or early summer, homeowners can spot swarmers around the house or inside. The swarmers inside the house usually congregate on the windows.

Homeowners also spot frass near wood with an infestation. The frass looks like sawdust, but it is very fibrous and has ant fragments. If the ants infest decayed wood, the frass will be darker, and the fragments will have a square shape. Frass can be found in areas like attics, basements, dark closets, under porches, and other places.

Moreover, with minimum background noise, people can hear gnawing or rustling sounds on the wood where ants are nesting. Another sign of ant infestation is failure of wood after excessive stress like a wind storm, moving heavy furniture, or accumulation of heavy snow on the roof.

How to Prevent Ants

In many cases, simply eradicating the existing ants is not enough to stop them from coming back; you also need to do some kind of preventative control. When an ant enters your home for the first time, it’s looking for food. If it finds some, it leaves an invisible trail from the food source back to its colony for other ants to follow. Ants can enter through very small cracks and crevices as well, so it’s important not just to kill the ants currently in your home, but to eradicate their trail and seal up any cracks or crevices with caulk ³ to ensure they cannot re-enter.

• Ensure you keep your kitchen extra clean, and ants will lack food and shelter.
• Dirty dishes are ant bait. Clean them immediately after use or rinse them and immerse them in soapy water.
• Use soapy water to mop food spills and remove crumbs.
• Take out the garbage often.
• Seal all the kitchen containers tightly.
• Cover all jars and containers and store them appropriately.
• Fix all leaks and replace damp wood.
• Sweep up crumbs in a timely way
• Seal up any cracks in your foundation or around windows and doorways to prevent the ants from entering
• Kill any large colonies of ants or large mounds on your property

Termite Extermination vs. Ant Extermination Cost

If you find evidence that insects have been eating the wood in your home, you may not be able to tell at first glance if they are ants or termites. Both will wreck havoc on your home, but in very different ways. Termites actually ingest the wood, while the ants tunnel through it. To tell the difference, take a look at the damaged area. A termite is a messy pest, leaving behind a lot of soil and debris in its wake; an ant is clean and will leave behind neat tunnels and passages through your wood. Both should be treated immediately to prevent future damage.

There is also a difference in the extermination methods and the cost of extermination for termites and ants. Professional ant exterminators will use approaches like mound control, poisoned bait, and chemical spray treatment. On the other hand, professional termite extermination methods include baiting, liquid termiticide, Micro treatment, heat foam sprays, and fumigation.

The only similarity is the use of poisoned bait, which the pests carry back to their colonies to cause extermination.

Generally, it is more expensive to exterminate termites than ants. The average cost of termite extermination ranges between $600 to $2,400, while the average cost of ant extermination is $150 to $1,000.

One Time Ant Treatment vs. Contract-based Ant Treatment

A one-time treatment means they will only offer their services once. The cost of this kind of treatment ranges from $90 to $250. Some factors will determine the cost, for example, types of ants, size of the property, and severity of infestation.

Contract-based ant treatment services mean that the professionals will offer scheduled recurring ant treatment services. It could be monthly or quarterly. They charge around $40 to $45 per month and $100 to $300 for quarterly contract-based ant treatment.

Professionals will normally recommend one-time ant treatment for a small ant infestation, or extermination on small properties. They will recommend a contract based ant treatment for a severe, recurring ant infestation, or large properties.

Enhancement and Improvement Costs

General Pest Control Treatment

A general pest treatment involves some kind of chemical spray which kills not only most types of ants but other types of insects nearby. Usually, your foundation and other typical areas of entry are sprayed. However, it does not work on carpenter or fire ants and does not stop them from coming back. You should pay $250 for general pest treatment.
