Wasp nests, should I collect them
Specifically yellow jackets, I have a friend who has a bit of an infestation of nests. He used some spray to kill them, and I wanted to see if I should collect them for use.
I know if I leave it outside for a good hot minute in the weather or rinse it myself, the residue from the spray will lessen and but still be there in small amounts.
My question is mostly about the spray and if it would affect any work I did with the nest. Has anyone used wasp nests that were treated? Did it affect your working?
