These handy small hive beetle (SHB) traps fit between the top bars of your brood box frames, and are filled with vegetable oil. Since hive beetles love small, dark spaces, they enter the trap through the holes on top, and are drowned in the oil below. It's best to use two of these traps per hive, and place them between the outer frames. Fill about 2/3 full of oil.
Had a weaker hive that I put these in and both traps were loaded in less than a week. Stronger hives had no beetles in the traps. Leaving them in anyways. Very easy to use. Highly recommend. Will definitely be getting more on my next order.
