The pests Chicago homes deal with
Carpenter ants
Carpenter ants excavate nesting galleries in damp or water-damaged wood — around leaking windows, in porch columns, under flat roofs. They do not eat wood, but years of tunnelling weaken it, and the parent colony is often in a tree or stump outside with satellite nests in the walls. Chicago inspectors tap window frames, porch posts and bath-trap wood with a probe, listening for the hollow sound that gives a gallery away, then trace the night trails back toward the parent nest.

Overwintering pests
Overwintering pests — stink bugs, lady beetles, boxelder bugs, cluster flies — share one strategy: enter the wall voids in autumn, wait out the cold, and emerge at windows on warm winter days and in spring. The treatment window is therefore late summer and autumn, at the exterior, sealing and treating the sun-warmed walls before the gathering starts. Chicago providers book autumn early for a reason: once the first cold snap pushes stink bugs and lady beetles into the wall voids, the honest options narrow to waiting them out — the work that counts happens on the exterior, weeks before. More about general pest control.
House mice
Signs accumulate quietly: droppings in drawer corners, gnawed packaging, a musky smell in a warm void. Inspectors track the pattern to the entries — utility penetrations, garage door corners, gaps at the foundation — then trap out the population and close the routes, checking traps across follow-up visits until the signs stop. Around Chicago, mouse work is measured by the follow-up: traps checked, catches counted, and the entry points sealed in the same programme — a visit that only sets traps is understood locally to be half a job.

Brown recluse spiders
Identification matters, because many harmless spiders are blamed for this one. Providers confirm the species — the violin marking, six eyes, the habitat — before designing the programme, then combine trapping data with targeted void treatment and storage changes, re-checking trap counts over visits to show the population trending down. In Chicago, recluse work starts in the storage rooms: glue traps along baseboards map where they actually travel, and the treatment map follows the trap map. More about spider control.
Subterranean termites
The structural pest that matters most here is the subterranean termite. Colonies forage from underground nests and build pencil-width mud tubes up foundation walls to reach wood, which is why damage so often stays hidden until it is extensive. Annual inspections are the standard defence in country like this. In Chicago, inspectors probe the foundation line and any wood within reach of soil first, because that is where local colonies announce themselves — a single mud tube on an inside crawlspace wall is taken as seriously here as a swarm.

Wasps and yellowjackets
Stinging insects follow the heat: by late summer yellowjacket colonies in the ground and in wall voids hold thousands of workers and defend them hard. Early-season nest spotting and professional removal keep the problem small. In Chicago, spring is the cheap season for this work: a queen founding a nest in April is a five-minute job that becomes a full colony, protective gear and a dusk appointment by August.

Bed bugs
Bed bugs arrive as hitchhikers — in luggage, used furniture, and between units in multi-family buildings — and establish in mattress seams, bed frames and upholstered furniture. Dense housing and heavy travel make inspection-led treatment a standing need in the metro. Local experience in Chicago is blunt about shortcuts: a single spray visit has never ended one of these infestations here. Preparation, treatment and a verified follow-up are sold as one programme because that is what the pest's egg cycle demands. More about bed bug treatment.
Raccoons and squirrels
Raccoons, squirrels, opossums and skunks treat attics and crawlspaces as ready-made dens — warm, dry and safe from predators. Removal is governed by state rules and by biology: young in the den change the plan. Providers inspect for the entry and the occupants, use eviction or trapping as the law allows, then seal and clean, because an unsealed den is simply re-let. In Chicago, wildlife calls follow the houses as much as the animals — roof junctions, vent stacks and soffit corners of a certain age are the entries, and the inspection reads the building before it reads the animal.
