Average ant exterminator cost

An ant exterminator costs $200 to $300 for a one-time treatment of a 2,000 SF home or $800 to $1,200 to treat severe infestations. Extermination companies use borax, pyrethrins, and other insecticides to treat fire, sugar, and carpenter ants. Common ant control methods include baits, sprays, and mound treatments.

Ant exterminator cost factors

The cost of ant extermination depends on the size of your home, the size and location of the infestation, the type of ants you have, and the treatments required to eliminate them.

Infestation level

The severity of the ant infestation affects the number of visits, time spent, and effort required by an exterminator. Mild infestations of small colonies are easy to treat using inexpensive DIY treatments, while treating networked colonies in the walls or massive infestations in the soil below the home is difficult and costly.

Severity Average cost
Mild infestation $150 – $300
Moderate infestation $300 – $700
Severe infestation $800 – $1,400+


Most ant nests are found outside the home, but ants go inside searching for a food source. In the kitchen, they dine on open food containers or pet bowls. Treating outside spaces is easier but the larger area uses more chemicals. Inaccessible attics or crawl spaces are more difficult and costly.

Ant extermination cost by location
Location Average cost
Kitchen / pantry $80 – $300
Bedroom $200 – $500
Whole house $300 – $400
Carpet $100 – $300
Floorboards $150 – $350
Walls / ceiling $100 – $500
Heating ducts $135 – $350
Window frames $125 – $400
Basement / attic $150 – $600
Under house foundation $175 – $500
Yard $100 – $500
Shed / garage $100 – $600

  • Kitchens are easy to treat since you can follow the trail from the food to the nest. Once you treat the nest, simply throw away the contaminated food to prevent a recurrence.

  • Removing ants from the bedroom is more complex because the ants hide in clothes and walls and finding them is more difficult. Since you can't simply throw away your clothes, you may deal with multiple reinfestations.

Ant types

Another factor in the cost of ant control is the type of ants you have. There are about 25 species that will infest a home. The most common ant infestations in the US are sugar ants, fire ants, carpenter ants, and pharaoh ants.

Ant control cost by type
Ant type Average cost Description
Fire $100 – $300
  • Most common in the southern states, the red or brown stinging ants are from 1/8" to 1/4" in size with mounds as tall as 7".
  • These ants tend to be less active in the heat of the day.
Sugar $200 – $250
  • Found throughout the US, these small black ants are about 1/16" in size. Males are all black, while females have an orange coloring.
  • They tend to invade pantries in search of sugars and syrups and are most common in July and August.
Pharaoh $200 – $250
  • Usually found in or around homes, these tiny ants are about 1/16" in size and have varying colors of yellow, yellow-brown, and light red.
  • Pharaoh ants invade homes by squeezing through the smallest of entries, then hiding deep inside walls.
Argentine $200 – $300
  • Found in the southern states, these light brown to black ants are about 1/3" long.
  • The wingless ants have 12 segmented antennae and give off a rotten coconut-like odor when crushed.
Carpenter $250 – $500
  • Common in wooded or rural areas throughout the US, these black ants vary in size and can be winged or unwinged.
  • Carpenter ants do not sting but cause structural damage to wood where they bore through to make nests.

Treatment methods

Exterminators use several different methods to get rid of ants, each with their own treatment costs. Common ant control methods include barrier spray, mound treatments, and poisoned bait. More severe ant infestations may require a combination of two treatments or costly tent fumigation.

Ant extermination cost by method
Treatment Average cost Details
Barrier spray $80 – $120
  • Spray repellents are common during repeat monthly or quarterly visits around drains, appliances, and kitchen cabinets.
Mound treatment $100 – $250
  • Treating the mounds is effective for fire ants.
  • A chemical powder is inserted into the mound to kill the queen and destabilize the colony.
  • The treatments can take up to a week for the queen to die.
Poisoned bait $120 – $200
  • Bait traps are one of the most popular treatments for ants in the home.
  • The ants feed on the bait and carry the poison back to the colony.
  • Traps take about a week to reach full effectiveness and may need quarterly replacement to prevent re-infestations.
Two-step method $600 – $900
  • Combining bait traps with sprays or mound treatments is common, especially for larger infestations both in the home and yard.
Tent fumigation cost $1,500 – $4,000
  • Fumigation is primarily used when all other ant control methods fail.
  • This costly treatment includes tenting the home and pumping gaseous pesticides through the space for about 3 days to kill ants.

These treatment methods use several different chemicals to treat ants, including:

  • Boric acid –A natural insecticide for killing ants, this slow-acting poison is used in baits or dusts.

  • Pyrethrins –A type of botanical insecticide derived from chrysanthemum flowers, pyrethrins kill ants on contact.

  • Permethrin – Asynthetic pyrethroid, similar to pyrethrins, these insecticides kill ants on contact.

  • Fipronil – This is a newer insecticide that is effective at killing ants systemically, meaning it is absorbed into the ant's body and kills it over time.

  • Abamectin – This slow-acting poison is commonly used in baits or dusts.

  • Hydramethylnon – This is a type of hydrazone, another slow-acting poison used in baits or dusts.

Treatment frequency

The cost to rid your home of ants depends greatly on the frequency of treatments. A one-time ant treatment costs $200 to $500 but pest control companies value repeat business and charge less for regularly scheduled services. Larger or recurring infestations require regular monthly, quarterly, or annual appointments.

Ant control costs by frequency
Frequency Average cost per year
(2,000 SF home)
One-time visit $200 – $500
Monthly $900 – $1,200
Quarterly $400 – $500
Annually $100 – $300

DIY ant removal vs. exterminator

While DIY ant treatments save you money, getting rid of ants on your own is not always possible. Over-the-counter ant treatments may be ineffective against large-scale or repeat infestations. Pest control services cost $250 to $600 on average to treat for ants along with other pests in your home and yard.

DIY ant treatment costs
Treatment Average price Details
Granule ant baits $10 – $20 Easily spreadable poison for large areas, including your yard and home's perimeter
Gel ant baits $20 – $30 Seeps into hard-to-reach cracks and crevices but covers less area than granules
Bait stations $20 – $30 Easy to place but can't reach into small spaces like granules or gel

In addition to over-the-counter chemical treatments, there are several natural remedies for ant control, including:

  • Diatomaceous earth kills ants by lacerating their hard exoskeletons and dehydrating them. DE is applied in thin layers in hard-to-reach areas between cabinets.

  • Borax kills ants by disrupting their digestive system. A mixture of 1 part borax to 3 parts powdered sugar is placed under appliances and inside cabinets where pets or children can't reach it.

  • White vinegar makes a good ant spray as the acid kills ants and disrupts their scent trails, making it harder for more ants to follow the path.

  • Spices with strong scents like cinnamon, red pepper, mint, and coffee grounds deter ants from an area.

  • Cucumber and citrus fruit peels contain chemical compounds similar to those found in ant repellants. Placing these near an area of ant activity may encourage the ants to move out.

Signs of an ant infestation

Obviously, seeing a trail of ants marching from the window to the pantry is an indicator of an ant infestation, but there are less obvious signs you should be aware of, including:

  • Ant trails – Ants leave thin, dark lines leading from food sources to the nest.

  • Sawdust trails – Carpenter ants chew wood but don't eat it, leaving behind piles of sawdust.

  • Ant nests – Mounds of dirt in your yard indicate exterior ants, while hearing rustling noises in your walls may indicate ants or other pests in the home.

  • Ant droppings – Small, dark pellets found near food sources or around ant nests are a common sign of an infestation.

  • Wood damage – Hollow-sounding beams or floorboards may indicate ants have burrowed inside.

  • Food contamination – In the pantry, ants will often eat food and leave behind empty containers and ant droppings.

How to prevent an ant infestation

The best way to treat an ant infestation is to prevent them in the first place. Since ants are usually in search of food or a place to nest, following these steps can help prevent an infestation:

  • Keep your home clean and free of open food sources. Store food in sealed containers and don't leave pet food out unless it is mealtime.

  • Clean up drink spills and dirty dishes that attract ants.

  • Seal cracks and crevices around doors, windows, and the foundation to prevent small openings that allow ants in your home.

  • Remove moisture sources like leaky pipes and seal any leaks around windows or doors.

  • Plant mint or lavender around the home to deter ants.
