Come September and October, boxelder bugs gather by the hundreds on the south and west sides of homes, especially near boxelder and maple trees. They do not bite, sting, or damage wood, but they slip through tiny gaps around windows and siding, then stain walls and curtains with reddish droppings. Vacuuming handles the ones inside. The lasting fix is exterior treatment plus sealing entry points in late summer, before the clustering starts. Homes with mature trees and light-colored siding draw the biggest crowds.

Cluster flies spend winter as adults inside wall voids and attics, then emerge sluggishly on warm days — one mild afternoon in February can send dozens buzzing against bedroom windows. Their larvae develop in soil outside, so spraying the interior does little. The effective approach is sealing the attic and upper-story gaps they enter through in late summer and treating the exterior before fall. Grand Rapids homes with older rooflines and loose soffits see the heaviest invasions.

Carpenter ants do not eat wood; they carve smooth galleries into damp, softened wood to nest. Around here they favor moisture-damaged window frames, porch posts, and deck boards — common in older neighborhoods like Heritage Hill and Eastown. Sawdust piles beneath a window or faint rustling inside a wall are the giveaways. The fix is finding and removing the nest, correcting the moisture problem, and treating the colony. Killing the queen is what ends it, and that usually takes a professional.

When temperatures drop, deer mice and house mice look for warmth, and a garage door gap or foundation crack is all they need — a mouse fits through a hole the size of a dime. They chew wiring and insulation, contaminate stored food, and leave droppings in basements and pantries. Trapping removes the ones inside, but exclusion is what stops the next wave: sealing gaps, screening vents, and keeping clutter away from the foundation. Fall is the right time to get it done.

German cockroaches spread fast through apartments and multi-unit buildings, traveling along pipes and shared walls. They hide behind appliances and under sinks, and a daytime sighting usually means a large population. Baiting and targeted crack-and-crevice treatment work far better than sprays, which scatter them. In dense housing, every connected unit needs attention — treating one apartment while the neighbor's goes untouched just moves the problem. Restaurants and food businesses downtown face the same pressure.

Subterranean termites thrive in the damp soil along the Grand River corridor and in low-lying yards after wet springs. Winged swarmers in April or May are the classic warning sign, along with mud tubes climbing foundation walls and wood that sounds hollow. They work silently for years, so an annual inspection is the smartest protection for homes with crawl spaces or wood touching soil. Treatment means a liquid barrier or baiting system placed by a professional — not a hardware-store spray.

By August, yellow jacket colonies are at full strength and foragers turn aggressive around grills, trash cans, and drink cups. They nest in wall voids, under eaves, and in the ground along fence lines. Paper wasps hang their open-comb nests from porch ceilings and deck rails. Knocking down a nest yourself risks multiple stings, especially with ground nests you cannot see. A technician treats the nest directly, usually in the evening when the colony is home, and removes it safely.
