How to Get Stink Bugs Out of My Room for Good

The brown marmorated stink bug produces an incredibly offensive odor when scared. A native to Asia, the BMSB accidentally arrived in North America in 1996. Stink bugs enter homes during the autumn to find hibernation spots for the winter. Removing stink bugs from the home without the bugs emitting their stench is labor intensive. The best way to keep stink bugs out of a room for good is to make sure they cannot get inside.

Household silicone or silicone-latex caulking
Weather stripping (if necessary)
Fine wire mesh
Dustpan and brush
Exterior pyrethroid spray

Instructions

- 1
  Fill in cracks where stink bugs can enter a room with household silicone or silicone-latex caulking. Check cracks around pipes, fascia, trim, siding and chimneys. Fill cracks with weather stripping around doors and window frames. Foundation vents that help ventilate the home need fine wire mesh placed over entrances to let air come and go but to keep stink bugs out.
- 2
  Remove window air conditioners in early fall, before stink bugs begin searching for hibernation spots. Stink bugs can still enter rooms when an outside cover has been placed on a window air conditioner.
- 3
  Remove living stink bugs found inside a room gently by lightly brushing the bug onto a dustpan. Dispose of the bug outside or flush immediately down a nearby toilet.
- 4
  Spray the outside walls of a home with a pyrethroid insecticide such as cyfluthrin, tralomethrin, deltamethrin or lambda-cyhalothrin. Spray in the autumn once a week because pyrethrins break down quickly in sunlight.
