What Attracts Stink Bugs in Your House?

Shelter

When temperatures drop in late fall and early winter, stink bugs move inside to begin diapause, a hibernation-like state where metabolism slows and they go dormant. Indoor shelter provides warmth and safety from predators.

Warmth

Attics, walls, and crawl spaces are perfect hiding spots. They become active again when weather warms up. A warm spell in winter can trick them into thinking spring has arrived, drawing them out prematurely.

Pheromones

Once a stink bug finds a good spot, it releases a pheromone that attracts others. Basically, once a single stink bug is attracted to your home, large numbers will follow.

Lights

Like many bugs, stink bugs are attracted to bright lights. Brown marmorated stink bugs are also drawn to blue lights and UV black lights. Turn off exterior lights when not in use.

Ornamental Plants & Produce

They may be drawn inside if you do not store produce in the refrigerator, leave scraps lying around, or grow produce near entry points.

Areas Resembling Natural Habitat

In nature, stink bugs shelter beneath rocky crevices or dead tree bark. They may be attracted to dark spaces with natural wood materials in your home.

Exclusion (Best Method)

Seal gaps, crevices, and access points as tightly as possible:

• Windows and door frames
• Baseboards and siding
• Utility boxes and pipes
• Water spigots
• Close fireplace flue when not in use
• Replace torn screen doors

Materials: Foam sealant, caulk, mesh screens, tape, sweeps

Removal

If stink bugs get inside despite sealing efforts:

• Vacuum: Easiest method (vacuum may smell temporarily)
• Bug catcher or water bottle: Scoop and discard once contained
• Do not crush: Releases foul odor
