For many homeowners, there’s no worse indication of an unkept or filthy home than an infestation of pests – like ants. If you find ants inside your house, it’s highly likely that you also have them outside. Depending on the type of ant that you have, you may have to tackle nests or mounds to prevent them from getting inside. Though, for the majority of ant infestations, this isn’t a problem.

Although some folks elect to try to handle the ant infestation themselves, the traps that you purchase from the store typically only affect the ants that you can see. For best results – and especially if you have a major infestation – you need an ant exterminator to come out to your property, target the whole colony of ants, and prevent them from coming back. Not to mention, most store-bought treatments aren’t effective on carpenter ants and fire ants.

The average ant exterminator cost is $250 for a 3,000 square foot house. Homeowners can spend $100 for standard ant repellant treatment, and advanced two-step extermination costs $750. It costs $150 to use poisoned ant bait, homeowners spend an average of $5 per ant mound for extermination.

Ant Extermination Cost by Home Size

Some ant exterminators base the cost of their services on the square footage of a home. As you might expect, professionals have to use more chemicals and more labor is required for larger homes and properties. As such, the larger the home, the more you’re going to pay for ant extermination. Here are some estimated treatment costs based on square footage:

Home Size by Square FootTreatment CostQuarterly Treatment Cost
2,000 square feet$160$100
2,000 to 3,500 square feet$180$110

Ant Extermination Cost by Type of Ant

There are countless species of ants across the globe, though most that live in the United States will see some of the more common types frequently. Although you don’t want to have any type of ant inside of your home, there are some that are more harmless than others. Knowing the type of ant that you have in your home will help determine the appropriate treatment for removal.

Not to mention, the type of ant that is infesting your property has a major impact on the cost of extermination, as ants like the fire ant and the carpenter ant cannot be eradicated by DIY methods.

Carpenter ants may be winged or wingless, are usually black, and can vary in size. They are found throughout much of the United States, but are most commonly seen in wooded, rural areas. Unlike fire ants, carpenter ants do not sting. However, these ants are the most expensive species to control since they are notorious for returning.

Oftentimes, carpenter ants are mistaken for termites since both can cause structural damage to wood. However, carpenter ants bore through wood to make their nests, rather than consuming wood as termites do. The cost to exterminate carpenter ants is about $500.

Ant Extermination Cost by Method

The type of extermination method that you or the professional you hire use typically depends on where the infestation is located and the type of ant that you have.

MethodAverage Cost
Ant Repellent$100
Mound Control$125
Poisoned Bait$150
Two-step Method$750

Ant Repellent

You’ll pay an average of $100 to have a professional come out and treat a defined area of your house using ant repellent. Ant repellent is a type of pesticide that is specifically designed to keep ants away from your house, without completely exterminating them. The goal is to make the area unappealing to the ants to prevent them from nesting on your property. Some common forms of pesticides formulated to repel ants include gels, aerosol sprays, and powders.

Ant Mound Treatment

This method costs around $5 per mound, with an average total treatment cost of $125. When it comes to controlling fire ants, the mound control method is the most effective. This method involves your exterminator drilling into the mound to apply a chemical powder that kills the queen and colony inside.

This process is very challenging and time-consuming, as the professional has to ensure that all the mounds are taken care of. Oftentimes, this method is used in conjunction with additional interior methods.

Poisoned Ant Bait

If you use bait to eliminate your ant problem, you can expect to pay around $150. This interior control method involves placing poisoned bait in designated areas throughout your home that the ants frequent. The ants will then carry the bait back to their nests, where it will kill both the carriers and the other ants. This method is effective at controlling most types of ants.

Though, it’s important to note that this method may take up to 7 days to work, and must be repeated frequently to prevent the ants from returning.

Two-Step Extermination Method

The average cost of a two-step extermination method is upwards of $750. This method involves mound control and another type of control method – whether it’s poisoned bait or spray – for controlling the colonies and eliminating the ants inside. It is typically very effective at eradicating fire ants, but can sometimes miss other types of ants.

Ant Extermination Cots by Level of Infestation

Ant exterminator costs may also depend on the level of infestation you have, as this determines how much expertise and labor are needed, along with the method and duration of the extermination. The level of ant infestation is usually determined by how long the ants have been infesting your property.

Level of InfestationAverage Cost

Small Ant Infestation

Small ant infestations are infestations that are recent. At this point, the ants are trying to grow their colony and you’ll have only spotted a few. With this level of infestation, signs of infestations are small and more difficult to notice. As such, the cost to control a small infestation is around $250, using pesticides or baits.

Medium Ant Infestation

Medium ant infestations are indicative of a growing colony of ants and you’ll notice more ants roaming around. The cost to control a medium ant infestation is around $350 for treatment areas under 3,500 square feet.

Large Ant Infestation

Large ant infestations are a huge nuisance, as the ants are highly noticeable. You’ll see more grass and holes in wood, along with mounds. A large infestation will usually cost you around $500. Though, the cost will increase if you need multiple visits from a professional. In this case, expect to pay between $75 and $100 for each follow-up visit.

Severe Ant Infestation

With severe ant infestations, the colony is huge and the ants can be found in more areas throughout the home. Since the colony is so big, the worker ants have to be more active to find food. The cost to control a severe infestation could be about $1,000 for professional services, especially if the infestation requires the two-step removal method.
