Bees chase the small hive beetles (SHB), which like to hide in dark places, into these dark crevasses. Start with one trap per hive and increase if you have a heavy infestation.
- Fill trap 1/3 of the way with vegetable oil.
- Clip bottom piece to black grated top piece, then place between top bars of the frames in the upper-most super. Bees will secure with propolis.
Hint: For easier cleaning, spray the trap out with a hose while tipping it over a garbage can.
