Can Anyone tell me about a bee vac? Is this just a shop vac, or do you have to make modifications? How do you use it to recover a colonie from a structure? I just removed 3 colonies from a house that was being demolished, aaaand it was a total disaster for the bees. I lost all 3 colonies. I thought if I could vacumn the bees out before i cut the comb out i would have a better chance at saving the bees.
