Where to Find Stink Bugs in the Home

Did you see a stink bug in your chimney or in the fireplace? If so, you’re not alone.

Stink bugs may travel long distances to find overwintering sites and often congregate in large numbers once they find a suitable area, attracted by a chemical emitted when they find a good site.

Because stink bugs may remain hidden for months, by the time they are spotted they may be difficult to completely eliminate.

Western’s Stink Bug Reduction program provides an initial inspection in the late summer or early fall to look for stink bugs in common hiding spots and to identify areas where stink bugs may gain access.

A very common entry point and hiding spot for stink bugs is the chimney, an area which provides warmth, darkness and easy access, usually through an open damper.

Western recommends closing the chimney damper whenever the fireplace is not in use, as well as using the fireplace periodically to help mask or destroy the pheromone that stink bugs emit. These simple solutions can go a long way in blocking stink bug chimney access.

Other Hiding Spots
While stink bugs in chimneys is common, they may hide in several other areas of your home, particularly where warmth is in abundance:

  • Attics
  • Baseboards
  • Window trim
  • Exhaust fans
  • Items brought in from outside
  • Vents

When Are They Active?

Western’s Residential Sales Manager, Sal Presti, explains:

“In spring, homeowners will definitely see stink bugs starting to emerge with the warmer temperatures. They have been hiding out in the home all winter and want to go outside. Hidden in every nook or cranny of a home, these pests will be seeking an exit as they come out from overwintering.”

Stink Bug Entry Points

  • Fireplace chimney
  • Poor fitting window & door frames
  • Torn screens
  • Behind exterior siding
  • Around utility pipes & cables
  • Cracks & gaps behind fascia boards
  • Poor fitting garage doors
  • Gaps around window air conditioning units

What Attracts Them?

“Stink bugs are actually attracted to lighter colored houses. Although they might appear anywhere on the siding, the southwest side of most buildings is where you may find them as well, because that is where it is the warmest and where they get the most afternoon sun in the winter.” – Brian Durham, Branch Manager

Our NYC and Northern New Jersey Technical Specialist offers these helpful tips to prevent them from getting inside in the first place:

“Be sure to seal all cracks around windows, doors, siding, utility pipes, outlets, behind chimneys and underneath the wood awnings and other opening with caulk. These pests can squeeze through smaller holes than you’d expect. Replace all damaged screens on windows and doors, and consider replacing outdoor lighting with yellow bulbs, which are less attractive to stink bugs and other insects, like moths.”

If you’re already dealing with stink bugs in your home, use a vacuum cleaner hose to quickly remove them without crushing them. Discard the bag or empty the canister to prevent odor from spreading.
