Most common pest ants in Illinois

Pavement ant

Probably the most common ant in structures, the pavement ant, is so named because it excavates an underground nest and pushes the soil into conical mounds along rocks, concrete slabs, sidewalks and driveways. Nests also can be found in logs, mulch, wall and floor voids, and insulation. Pavement ants are dark brown-black and about 1/6-inch long. They forage 30 feet or more from their nest in search of a variety of foods, including grease and oils, seeds, sweets and honeydew. They are often seen indoors after heavy rain drenches their underground territories.

Odorous house ant

This 1/8-inch long, brownish-black ant can be confused with the pavement ant, until the odorous house ant is crushed, releasing an odor like rotten coconut. In recent years it has become an increasingly common household invader. Nests are found under rocks, boards and other debris, and in floor and wall voids. These ants will move indoors during rains and in the fall. They feed on sweets, honeydew, plant and fruit juices, meat and dairy products.

Carpenter ant

Most ant species are not immediately harmful to your home, with the exception of Carpenter ants. Carpenter ants are considered a wood-destroying insect, and can cause significant damage to your home if they are not stopped immediately. These pests dig through and nest in the wood inside your home and can eventually weaken the structure, in addition to any cosmetic damage they cause. Indoor nests are usually “satellite” nests connected to the colony’s main nest outdoors. Satellite nests are often established in wood where moisture problems exist (e.g., around leaking pipes, inadequately sealed window frames and roof leaks). To identify a carpenter ant infestation, look for big black ants and piles of "sawdust" near any wood in and around your home.  Carpenter ants are also more resilient than most other ant species, and are immune to most home remedies. 

Pharaoh ant

Another resilient ant species that can survive most remedies is the Pharaoh ant. This tiny (1/12-inch) ant is yellow to reddish-brown. Pharaoh ants nest in voids in floors, walls and ceilings. They often infest large buildings. In hospitals, these ants pose a health risk because they can carry infectious bacteria from the warm, moist areas they inhabit, to intravenous fluids, blood and wounds. These ants are problematic for pest management, as the colonies of this ant do not spread by swarming, but instead by “budding,” breaking apart and establishing sub-colonies in new locations. This process can be triggered when the colony is stressed by the application of repellent liquid or dust pesticides. Colonies can be very large, some containing more than 100,000 ants. Though not as common as the other ant species, these and carpenter ants typically require professional service to effectively control and eliminate. 

How we get rid of ants

Though ant problems can often be resolved with DIY methods such as ant bait and over-the-counter sprays, these methods do not always work, and rarely provide a long-lasting solution. The products available to homeowners usually leave residue and odor, and can in fact be more toxic than what is available to professionals, due in part to the use of petroleum distillates. At Pest Arrest, the majority of the treatments we apply are EPA certified low-risk, with the active ingredients often used in flea treatments for pets. All of our technicians are trained in Integrated-Pest-Management, and we utilize the safest eco-friendly pest control products available. 


After an initial assessment, our licensed technician will explain the treatment process and what results to expect. Typically the ants are gone within a few days of the treatment, and the product will keep killing any new ones for up to three months. The products we use are known in the industry as non repellent micro-encapsulated residual treatments. This means that our treatments usually leave no visible residue and cannot even be detected by the ants. A thin invisible layer of microscopic capsules adheres to the surface on which the treatment was applied, and the ants continue to go about their business. Unbeknownst to them the treatment spreads like a virus, and wipes out the entire colony within days. The residual takes care of any stragglers. For continued peace of mind we recommend the ARREST™ System quarterly service, which protects against most common pests, including all species of ants. As an affordable exterminator in the Lake county area, we are here to help!
