Hive beetles are intetesting annoyances.
Ive not found anything that Ive tried really do any good.
But, it seems with me and my bees, text book or others experience does not apply! I seem to be the odd ball.
I have 7 hives. Out of the 7, one this year hive and one last year hive are heavily infested. Those two hives are the hardest working and most active hives I have. The flip side, which goes against things stated, I have a hive that has struggled all year. Queenless, have put in many frames of brood, egg, larvae (they never did make a queen), currently they have been dying off and for a while they do nothing. No forage flights nothing. Just hang around the entrace and stand there like statues. That weak, dying hive, has hardly no beetles. Ya gotta hunt hard to find one. My other 5 hives, the beetles are there, but not too bad. Im still learning and trying and hoping for a solution with these pests.
