Re: I used Check mite for SHB...
I just attended a class on SHB in Frankfort KY during the yearly bee school. Here are a few control measures I heard aboutfrom long time beekeepers in the class.
Put dense grade gravel beneath hives, it works like diamaceous earth killing the larva.e. Let it come out about a foot around the hive.
Agricultural lime will do the same.
Put 4-6 drops of wintergreen oil on a piece of cardboard or pollen patty. DON'T OVERDO IT!! The beetles will run from the hive but if you overdo it the bees will go with them.
I plan to try the wintergreen oil this year.
