I installed 2 pkgs in new hives 3-27; one have is very strong and doing excellent. The other hive has seemed to be somewhat behind from getgo. Discovered SHB and larva in pollen patty last Thursday 4-22. Plan on going back in hive tomorrow to check it very close and install bettle traps. Should that work if larva is not observed in comb?? Any idea on how to strengthen the week hive??? Would it be a bad idea to consider taking a frame of brood out of my strong hive and put in the weak hive?? From everything I have seen posted, CheckMite seems to be the only chemical available for beetles other than various types of traps. I have a SBB on both hives and can put a corrugated sheet under it to check for mites. I'm not sure, but don't believe there is room for any type of tray on Brushy Mt. SSB's for oil trap?? Any ideas would be appreciated. FYI there seems to be at least a 6 to 1 ratio of bees coming back to strong hive vs weak hive. Bees w/ pollen seem to be more like 10-1 strong vs weak hive. I have been feeding both hives since installation of bees on 3-27. The weak hive has 6 of 8 frames drawn and the strong hive has had another 8-frame deep added. I'm not sure whether part of the problem is a slow laying queen in the weak hive or just SHBs... Hopefully after a close check tomorrow there will be some answers. Ideas and suggestions would be appreciated. Thanks.
