My BIL is a bee-keeper in Sante Fe, NM. He is starting to have a problem with aggressive queens taking over his hives. He tries to remove them and replace them with less aggressive ones that he imports, and is having some success. But. . .
I am severely allergic to bee stings (4+) and try to avoid them, but I wanted to be a part of him tending his hives. So I gown up with protective clothing, hat, gloves and screened mask. When he opens the hive, he says OH-OH, and says: You should probably leave now, which I did. They were very aggressive, trying to attack him (us). He was unscathed, as was I but things are apparently changing for him?
