Stink bugs reach Fredericksburg homes in late September, settle into attics and wall voids through winter, and wander into living spaces on warm days before leaving in spring. Most advice covers only the fall flights, but the season runs from September to spring, and each stage has its own fix. Sealing in early fall prevents the whole sequence.

The Stink Bug Season From Fall to Spring

Early to mid September
Seal the home before the bugs arrive. Caulk gaps around windows, doors, siding, pipes, and fascia, and fit door sweeps.
Late September to October
Adults begin searching for overwintering sites, per Virginia Cooperative Extension. Flights are heaviest on sunny days that follow cool days.
November to March
Washington State University Extension notes attics are common overwintering sites, and bugs can emerge into the home during warm periods in winter. Vacuum any that appear.
Spring
Overwintering adults become active again and head back outdoors to feed on plants. Eggs and nymphs appear on the undersides of leaves from June through August.

Myth: Stink Bugs in January Mean a New Infestation

A stink bug crawling across the ceiling in midwinter is almost always one that arrived in fall. The bugs rest in attics and wall voids, then wake on warm days and wander. Killing them in the walls usually makes things worse, since dead bugs there give off an odor.

Common Questions About Stink Bugs in Fredericksburg

Why do I see stink bugs inside in the middle of winter?

Stink bugs overwinter in attics and wall voids and wake during warm spells. A bug in January usually arrived in fall.

When is the best time to seal against stink bugs?

Early fall, before adults begin searching for shelter in late September and October. Sealing after they have settled inside does little.

Will stink bugs damage my attic or insulation?

No. Stink bugs are a nuisance and do not damage structures or breed indoors. The concern is the odor when they are crushed or die in wall voids.
