“Don’t use wasp spray...”
I use Safer brand wasp spray.
The mint oil in it kills wasps but is safe for humans...
I don’t have bear spray but I do have a new bear-proof garbage can...
“...but I do have a new bear-proof garbage can...”
So...just drag the perp’s body to, and place in, your new bear-proof garbage can. Set it out at the curb on pickup day.
