Clip-on Small Hive Beetle Trap - 4-Pack
You typically use 2 of these per brood box, so 4 in a double brood box
Compare to the big catalog companies that charge 4 at $4.35 = $17.40
Most instructions will tell you to add vegetable oil to kill the beetles that fall into the trap. The problem is, you will periodically tilt a box which causes the oil to spill out all over the comb, ruining it. I HIGHLY RECOMMEND that you consider Food Grade Diatomaceous Earth. Fill the trap about 1/4 inch. When the bugs fall into the trap, this fine powder, which microscopically is very sharp crystals, will get in the joints of the beetles and kill them.
