This is the best Small Hive Beetle trap on the market! We have been using this for years and it really works! The product has a single center bay that will act as a bait. Baiting the trap is very important. You should use apple cider vinegar as a bait. The two side bays will hold mineral oil. The mineral oil will drown the small hive beetles when they enter the trap. The trap will need to be cleaned on a weekly basis.
