Can bifenthrin kill house centipedes?
Can bifenthrin kill house centipedes?
Yes. House centipedes are sensitive to insecticides (their thin body walls allow easy penetration), and bifenthrin is very effective against them.
Application methods
- Direct spray on the body: spray directly when seen; contact kills quickly.
- Residual spray: spray along corners, under cabinets, and on baseboards where they crawl; once dry, it forms a film.
- House centipedes that crawl over the treated surface absorb the insecticide through their abdomens and die within hours of contact.
- Residual effect lasts about 2-4 weeks.
Best timing for application
- House centipedes are nocturnal; spraying in the evening is most effective.
- They will contact the treated surface when they emerge at night to forage.
- Spray on walls, baseboards, and door gaps along their travel routes.
Precautions
- After spraying, wait for the spray to dry completely before allowing people and pets to contact the floor.
- Once dry, it is colorless and odorless and does not affect daily life.
- Avoid mopping treated areas immediately to preserve the residue.
- Bifenthrin only solves the immediate problem; long-term control relies on humidity management.
