Science-based solutions for pest and rodent problems.
Ants are the number one pest call we receive from Arlington Heights homeowners. The village’s combination of mature trees, older housing stock, and proximity to parks and forest preserves creates ideal conditions for multiple ant species to thrive — and to find their way into your home.
Quick Kill Exterminating has been eliminating ant colonies in Arlington Heights since 1990. We don’t just kill the ants you see — we locate and destroy the colony, including the queen, so the problem doesn’t come back.
Carpenter ants are the most destructive ant species in Arlington Heights and the one homeowners fear the most. These large black ants — typically 1/4 to 1/2 inch long — don’t eat wood, but they tunnel through it to build nesting galleries. A mature colony of up to 10,000 ants can cause real structural damage over time.
Arlington Heights is prone to carpenter ants because of its mature tree canopy. Older neighborhoods like Scarsdale, Stonegate, Westgate, and Fairview have decades-old oaks, maples, and elms — many with dead limbs, hollow trunks, or stumps that serve as parent colonies. From these outdoor nests, carpenter ants establish satellite colonies inside nearby homes, particularly where wood has become damp around windows, rooflines, chimneys, or bathrooms.
Signs of carpenter ants in your Arlington Heights home:
Small (about 1/8 inch), dark brown to black ants that nest in cracks in driveways, sidewalks, patios, and foundations. You’ll notice small mounds of sand or soil between pavement cracks — that’s their signature. They’re extremely common across every Arlington Heights neighborhood and forage indoors for sweets and grease. While they don’t cause structural damage, they’re persistent and difficult to eliminate without professional treatment because their colonies are hidden underground.
Named for the rotten coconut-like smell they produce when crushed, these small (1/16 to 1/8 inch) ants form massive colonies with multiple queens and tens of thousands of workers. They invade kitchens, bathrooms, and anywhere food or moisture is present. They’re notorious for “budding” — when stressed by over-the-counter sprays, the colony splits into multiple smaller colonies that spread throughout your home rather than solving the problem.
Tiny (about 1/16 inch) and dark black, these ants form trails along countertops, windowsills, and floors. They nest in wall voids, woodwork, and masonry. Common across all Arlington Heights neighborhoods and most active in summer.
You’re only killing the foragers. The ants you see are just 10-15% of the colony. The queen and the rest are hidden in the nest. Kill the visible ants, and the colony replaces them.
Repellent sprays make things worse. Most store-bought sprays are repellents — ants avoid the treated area and reroute to a different entry point. With odorous house ants, repellent products trigger colony budding, spreading the problem to new locations in your home.
The parent colony is often outdoors. Especially with carpenter ants, the main colony is typically in a tree, stump, or woodpile on your property or in the adjacent park or forest preserve. Indoor satellite nests keep getting repopulated until the parent colony is eliminated.
Arlington Heights has constant ant pressure. The village’s parks, mature trees, and green spaces support dense ant populations. Even after eliminating one colony, new ones will push toward your home. Ongoing prevention is essential.
Your Quick Kill technician inspects your home inside and out to identify the ant species, locate active nesting sites, map foraging trails, and find entry points. Different species require different strategies, so accurate identification is critical.
We apply a customized treatment based on the inspection. For carpenter ants, we treat wall voids and nesting areas directly, apply non-repellent products along foraging trails and entry points that transfer back to the colony, and treat the exterior perimeter. For smaller species, we use a combination of baits and non-repellent treatments strategically placed to maximize colony exposure.
We treat the foundation perimeter, entry points where utilities enter, window and door frames, weep holes, and any exterior nesting sites. This creates a protective zone that intercepts ants before they get inside.
We follow up to confirm colony elimination. On our quarterly program, your scheduled visits include ongoing ant prevention — adjusting treatments seasonally as ant pressure peaks in spring and summer.
March – April: Carpenter ants emerge from dormancy. Winged swarmers may appear inside homes — often mistaken for termites. This is when many homeowners first discover an interior nest.
May – June: All ant species hit peak activity. Pavement ants build sand mounds in driveways. Odorous house ants and little black ants invade kitchens. Carpenter ant trails are well-established.
July – August: Peak season. Maximum colony populations and heaviest foraging. Homes near parks and green spaces see the worst pressure.
September – October: Activity gradually declines but carpenter ants remain active until the first hard freeze. Good time for preventive treatment.
November – February: Most outdoor ant activity stops, but carpenter ant satellite nests inside heated homes remain active year-round. Large black ants indoors in winter means you have an interior nest.
Carpenter ants cause structural damage over time, but work more slowly than termites. Termites are quite rare in the Arlington Heights area — if you see large winged insects indoors in spring, they’re almost certainly carpenter ant swarmers. A mature colony left untreated for years can weaken structural wood, so prompt treatment matters.
A single treatment eliminates the existing colony, but Arlington Heights’ parks and mature landscaping continuously produce new colonies that push toward homes each spring. Quarterly maintenance creates a continuous barrier that prevents recolonization.
Yes. We use EPA-registered products applied in targeted areas — along baseboards, in wall voids, and around the exterior perimeter — not broadcast across living spaces.
You may see increased activity for the first few days — this is normal. Non-repellent products allow ants to carry the treatment back to the colony. Significant reduction within one to two weeks. Complete colony elimination typically within two to four weeks.
Cost depends on the species, extent of infestation, and home size. We provide free inspections and quotes. Call (847) 724-1511 to schedule.
