I "located" a nest of ground nesting yellow jackets yesterday while while weedwacking a path to one of my ladder stands. Only got stung 3 times but damn them things hurt!! Went back last night and sprayed a whole can of expanding foam ground hornet spray into the hole. After about an hour went back out and sprayed a good bit of charcoal lighter fluid down hole and lit it. The flame flickering out the hole for near 10 minutes was quite satisfying!!!
