Re: Shb ?
As per my state bee inspector, and common sense, it is the bee numbers that will keep the SHB from ruining your hive(s).
I agree with him obviously but his position is having any frame that has resources that the SHB could possibly find interesting covered with bees. This, to me, put a hive either on the verge of swarming due to lack of room, or in immediate danger of being slimmed.
I have also had weather very friendly to SHB and have found several hives with an alarming number of SHB in them. On those with huge SHB populations I used 6 beetle traps that go between the frames and have a section in the middle for a bait. I baited with pollen and dead SHB which was a recommendation from the inspector. I used soapy water in the traps. I came back to the hives with the big SHB problem and the traps were jammed with SHB and maybe had 5% of the original numbers scurrying around so I let the bees handle it.
I swore I wasn't going to use traps and that I was just going to let the bees take care of the SHB this year but I couldn't keep my word to myself. I had a fellow beek loose a three story 10-frame deep hive this year with about 100 lbs of honey in it. That is $600.00 to this person and it happened in a matter of a week. It was a site that would make a buzzard puke.
When a hive goes queenless and there is a flow on the hive looses 2000 bees per day according to what I've read. With a honey super to cover with dwindling bee numbers the SHB take over.
By & large I try to ignore SHB unless they look like they are just stressing the hive toward collapse.
Full sun helps a lot but makes for a hot hive for the bees. Avoid equipment that provides hiding places such as some plastic frames and metal frame spacers. I found a lot of beetles in the bottom groove of my frames and will fill these grooves in as I clean the frames of wax etc. Sort of like a putty application into the groove.
Between the varroa and these SHB bastards it is amazing we get ANY honey nevermind hives that live.
One good thing about the rain is that it will keep more bees inside to hopefully chase the SHB.
Very frustrating situation indeed.
