Pest Control for Chicago Single-Family Homes

Mice top the list — every Chicago neighborhood sees a fall mouse migration as temperatures drop. Bed bugs are second, typically introduced through travel or used furniture. Ants, spiders, wasps, and seasonal mosquitoes round out the most common calls.

Older homes (pre-1950) tend to see more rodent activity due to foundation settling and original construction materials. Newer construction tends to have fewer but more concentrated issues — often around attached garages and utility penetrations.

Mice can squeeze through openings the size of a dime. Common entry points include the gap under garage doors, holes around utility lines (gas, electrical, cable), foundation cracks, dryer vents, and unsealed weep holes in brick.

Bed bugs almost never enter through structural gaps — they arrive on belongings. Insects enter through window screens, weatherstripping gaps, and door thresholds.

Spring brings ants and the start of bed bug season. Summer is peak for mosquitoes, wasps, and bed bug activity. Fall is the most critical season — mice and rats move indoors and stink bugs look for overwintering sites. Winter is the time mice are already inside and most active.

One-time treatments solve immediate problems. Quarterly recurring service prevents most issues from developing in the first place by maintaining a treated perimeter around the home year-round.

One-time service makes sense for a confirmed active infestation. Recurring service makes sense for homeowners who want consistent prevention — particularly for homes with history of ant, spider, or rodent activity. Recurring customers also get priority same-day scheduling for any urgent calls between visits.
