I doubt there is any harm in most of that, except for the bees maybe

I don't think there is any chance of him getting parasites from it. I know in some parts of the world, people eat insects too. They are apparently loaded with protein .

I've worried about Tasha getting stung by yellowjackets in the late summer and fall, she snaps at anything that buzzes around her face whether it be a fly or a wasp, and she's pretty fast. She has gotten several flies in the house before. I try to just distract her when she is snapping at bees/wasps.
