Professional Pest Control Services in Chicago & Chicagoland

Most pest problems don’t start because a house is dirty. They start because pests found an opening — a gap in the foundation, a crack around a pipe, a door sweep that doesn’t quite seal all the way. In Chicago-area homes, freeze-thaw cycles widen those gaps every winter, which is why we see upticks in rodent and insect calls every spring.

Inspection First. We walk the property — inside and out — and look for signs of pest activity and entry points. This isn’t a 10-minute walkthrough. We check crawl spaces, attic access points, utility penetrations, and the perimeter of the structure. You’ll know exactly what we found before we treat anything.

Targeted Treatment. We don’t spray everything and hope for the best. We apply the right product to the right location based on what the inspection shows. A cockroach infestation in a commercial kitchen requires a completely different treatment than a spider problem in a residential basement. We adjust the approach to the situation.

Prevention and Follow-Up. After the initial treatment, we walk you through what to expect over the next week and when to call us back. For ongoing protection — especially helpful in Chicagoland homes dealing with year-round pest pressure — we offer recurring service plans.

We serve homes and businesses in Chicago, Woodridge, Naperville, Bolingbrook, Darien, Westmont, and across DuPage County. Call (630) 241-4269 for a free inspection quote.

Chicago consistently ranks among the top cities in the US for bed bug complaints — and it’s not just downtown apartments. We’ve treated hotels, condos, and single-family homes in Woodridge, Naperville, Bolingbrook, and across the southwest suburbs. Bed bugs don’t care about zip code or how clean the house is.

What makes treatment hard is that they hide well. They live in mattress seams, behind outlet covers, inside box springs, and in cracks in bed frames. A surface treatment misses most of them. Our process is more thorough:

Full Inspection. We go room by room and look in all the places bed bugs actually live. You’ll know what we found and where before we treat anything.

Targeted Treatment. Depending on what we find, we use heat treatment, chemical treatment, or a combination of both. We explain the options and let you make the call based on your situation.

Follow-Up Visit. Bed bug eggs can survive an initial treatment. A scheduled follow-up confirms the infestation is fully cleared — not just reduced.

If you’re waking up with bites, seeing rust-colored stains on your sheets, or noticing a faint sweet smell near your bed, don’t wait. The sooner you act, the less it spreads. Call (630) 241-4269 today. Learn more on our bed bug control services in Chicago!

Ant calls spike every spring across Chicagoland — usually starting in late April. We get a lot of calls from homeowners in Naperville, Bolingbrook, and Woodridge who thought they had a small ant problem and turned out to have carpenter ants working through the wood in their walls.

Not all ants are the same problem. Here’s what we commonly treat across the Chicago area:

Carpenter Ants — These cause real structural damage. They don’t eat wood, but they tunnel through it to build their colony. Signs include small piles of sawdust-like frass near wooden structures. A mature colony can be several thousand workers.

Odorous House Ants — The small black ants that trail across kitchen counters. They’re after your food, they build large colonies fast, and they return quickly if you only treat the visible workers and not the source.

Pavement Ants — Common along Chicago-area driveways and sidewalk cracks. They can find their way into homes through foundation gaps.

We identify the species first, then apply the right treatment to eliminate the colony at the source. For more detail, visit our ant control page. Call (630) 241-4269 for a quote.

The termite species you’re dealing with in the Chicago area is the eastern subterranean termite. They live in underground colonies — sometimes hundreds of thousands of workers — and they enter homes through the foundation, usually through hairline cracks in concrete or around pipe penetrations. Most homeowners don’t know they have termites until there’s visible damage.

Termite swarmers (the winged ones) typically appear in April and May after a warm rain. If you’re seeing what looks like flying ants near your foundation or windowsills in spring, there’s a real chance those are termite swarmers. That’s a sign of an active colony somewhere nearby.

Our termite process:

Inspection — We do a full inspection of the foundation, crawl space, basement, and exterior wood-to-soil contact points. We document everything and give you a clear report before recommending treatment.

Treatment — For active infestations, we use liquid termiticide applications to the soil around the foundation, creating a barrier the colony can’t cross. For ongoing monitoring, we also offer bait station programs.

Real Estate Inspection Letters — Buying or selling a home in the Chicagoland area? We provide termite inspection letters and work with real estate agents and attorneys across DuPage County regularly.

For more detail, visit our termite control page. Call (630) 241-4269 to schedule an inspection.

Beyond ants and termites, we handle the pests that don’t fit neatly into a category. In the Chicago area, those calls tend to cluster around a few specific problems:

Wasps and Hornets — Nests under eaves, inside wall voids, or in the ground. Yellowjackets are the most aggressive and they build fast — a colony that’s barely visible in June can have 4,000–5,000 workers by August. Don’t knock a wasp nest down yourself. We remove them safely and treat the area to prevent rebuilding.

Spiders — Most spiders in the Chicago area are harmless, but wolf spiders and cellar spiders make people uncomfortable, and brown recluse sightings have increased in suburban Illinois over the past decade. We treat perimeter and interior harborage areas.

Beetles — Carpet beetles, powderpost beetles, and grain beetles all show up in Chicagoland homes. Carpet beetles damage wool rugs, clothing, and upholstery — often without being noticed until there’s visible feeding damage.

Mosquitoes — We offer targeted mosquito control for residential yards. The wetlands near Bolingbrook and the DuPage River corridor make mosquito pressure higher in this part of the suburbs than in drier areas. We treat source areas and create a barrier around outdoor living spaces.

Dealing with something not on this list? Call us anyway. If it’s a pest problem in the Chicago area, we’ve probably treated it before. (630) 241-4269.

Chicago has ranked as the most rat-infested city in the United States for multiple years running. That problem doesn’t stop at the city limits — mice and rats push into the suburbs every fall when temperatures drop, and they’re looking for a warm place to spend the winter. Your house is ideal.

Mice can squeeze through a hole the size of a dime. Rats can chew through wood, plastic, and soft metals. Both contaminate food, chew through wiring (a genuine fire hazard), and reproduce fast enough that a small problem in October becomes a serious infestation by January.

Our rodent control process:

Inspection — We find where they’re getting in. This is the step most homeowners miss when they try to handle it themselves. If you trap mice without sealing the entry points, more mice will come in to replace them.

Trapping and Removal — We place and monitor traps in the right locations. Not just along walls — we understand the travel routes rodents actually use inside structures.

Exclusion — We seal the entry points. Gaps around pipes, cracks in the foundation, holes where utilities enter, spaces under exterior doors. This is what stops the cycle from repeating next winter.

We handle rodent control across Chicago, Woodridge, Naperville, Bolingbrook, Darien, and Westmont. If you’re hearing scratching in the walls or seeing droppings in your kitchen, call (630) 241-4269 before it gets worse.

Most spiders in Chicago-area homes are harmless — but when you’re finding them regularly, that’s not random. Spiders follow their food source. A consistent spider presence usually means your home has an underlying insect population feeding them, and the spiders are just the visible symptom.

Wolf spiders and cellar spiders are the most common calls we get across Woodridge, Naperville, and Bolingbrook. Brown recluse sightings have also increased in suburban Illinois over the past decade — they tend to turn up in undisturbed storage areas, garages, and closets. Any spider you can’t identify is worth having checked out.

Our spider control process:

Inspection — We identify the species, find where they’re nesting, and assess what’s drawing them inside. A wolf spider in the basement tells a different story than an egg sac cluster in a crawl space.

Web and egg sac removal — We knock down accessible webs and remove egg sacs. Leaving those behind means the next generation hatches in place.

Targeted treatment — We apply residual treatments to cracks, corners, and entry points where spiders and their prey are active — not just a surface spray.

Pest reduction — Where the inspection warrants it, we treat for the insects feeding the spider population. That’s the step that keeps them from coming back.

We handle spider control across Chicago and the southwest suburbs, including Woodridge, Naperville, Bolingbrook, Darien, and Westmont. If you’re seeing spiders consistently — or anything that might be a brown recluse or black widow — call (630) 241-4269 for an inspection.
