Your most important objective should be preventing them from successfully reproducing. Hive Beetle larvae need to reach the soil under the hive in order to reach maturity. You can prevent this by placing the hive on a concrete pad, a gravel/baserock pad, or a 3″-4″ layer of chipped/shredded tree limb mulch.
Hive beetles love pollen substitute. Be judicious when feeding pollen sub. Recommendation: try a couple of 2″ square pieces. They should be consumed within a few days.
