AR, hello buddy, see ya at the next bee meeting.
Mr. Ben, consider using a can of freeze spray. Available at amazon or local office supply stores as it?s used to blow dust off delicate computer parts. The spray is also used in doc office to freeze warts, moles, precancerous (spots) in skin. It is non flammable, non toxic and minus 62 F.
Mr. Ben, when a beek opens a hive, the beetles make a jail brake and typically 5-7 days later a beek opens the hive again to see slimed frames. This happens all the time in the South, even to yours truly.
So, I got tired of this jail break scenario and tried freeze spray. It is like this: now I open a hive, the beetles scatter and run into the bottom of the comb cell, I insert the tube that comes with the can of freeze spray into the cell, pull the trigger on the spray can and that beetle is a goner. The tube I am talking about is the same as used on WD-40 and inserts into the nozzle of the spray can. This tube directs the freeze with pin point accuracy, even blocks the beetle into the cell and a honey bee 1/2 inch away is unharmed. If there is an egg or larva on the opposite side of the frame, yes, it will be frozen, but a small price to pay.
Usually the beetle jail is in the outer frames, 1,2 or 9,10 where food is stored so freezing the opposite cell is of no harm. If bees are in the way, hold the can 8?10 inches away and give the bees a quick
blast of cold air. The bees willl scatter away from the beetles giving you a clear shot.
When I open a hive, every beetle is sprayed, I leave few survivors, as on occasion a beetle flys off, but I get him/her sooner or later leaving Van with a big smile.
Blessings
These beetles are very susceptible to freeze, drops them dead.
