To get rid of wood roaches, remove the ones you see with a vacuum or sticky traps, seal gaps around doors and windows, switch outdoor lights to yellow bulbs, and move firewood, leaf litter, and mulch away from the house. Unlike German or American cockroaches, wood roaches live outdoors and usually can’t survive long or breed inside, so the fix is mostly about keeping them out.
How to Identify Wood Roaches
- About ¾–1 inch long, chestnut brown
- Pale or yellowish edges on the shield behind the head and on the wings
- Males fly well and are drawn to lights; females have short wings
- Usually seen in late spring and summer
- Often found near firewood, decks, and wooded yards
Wood Roaches vs Indoor Cockroaches
| Wood roach | German / American roach | |
|---|---|---|
| Lives | Outdoors in leaf litter and wood | Indoors, kitchens and bathrooms |
| Breeds indoors? | Rarely | Yes |
| Behavior | Wanders in by accident, dies within days | Hides in cracks, multiplies quickly |
| Activity | Seen in daylight at times | Mostly at night |
How to Get Rid of Wood Roaches Inside
- Vacuum or capture any you see and release them outside.
- Use sticky traps along walls near entry points to catch wanderers and monitor activity.
- Reduce moisture with a dehumidifier in basements and crawl spaces.
- Remove indoor firewood—only bring in what you’ll burn the same day.
How to Keep Wood Roaches Out
- Store firewood at least 20 feet from the house and off the ground.
- Clear leaf litter and keep mulch a few inches from the foundation.
- Install door sweeps and repair window screens.
- Caulk gaps around pipes, vents, and siding.
- Use yellow “bug” bulbs outdoors or move lights away from doors.
- Clean gutters so organic debris doesn’t build up near the roofline.
Natural Methods vs Insecticides
Pros
- Sealing and yard cleanup solve the root cause
- Sticky traps are cheap and chemical-free
- Perimeter treatments outside can reduce invaders in heavy areas
Cons
- Indoor sprays aren’t needed for occasional wood roaches
- Chemicals don’t fix outdoor attractants
- Overusing insecticides can harm beneficial insects
Frequently Asked Questions
What kills wood cockroaches?
Vacuuming, sticky traps, and general insect baits or sprays kill them, but most die naturally indoors within days because it’s too dry for them.
Do wood roaches go away?
Yes. They don’t usually establish indoors, and activity drops after their summer mating season.
Why am I getting wood roaches?
Usually nearby woods, firewood, leaf litter, or outdoor lights attracting flying males, plus gaps that let them in.
What smells do wood roaches hate?
Strong scents like peppermint or citrus may deter them slightly, but sealing gaps and removing outdoor habitat work much better.
Are wood roaches dangerous?
No. They don’t bite or infest food like indoor roaches; they’re mainly a nuisance.
