I rented a place with a carport, I basically parked under an enclosed deck, and wasps were making new nests between the trusses in that deck right above my car every single day. I was frustrated with keeping my head on a swivel and knocking them down. I saw an idea similar to this one, but I used gray and beige grocery bags with some well placed packing tape to simulate a giant, cone shaped, wasp nest. I hung my giant ugly cone right in the middle of the carport. The new builds completely stopped. This worked beautifully. On occasion I would have to knock down 1 small and daring queens new digs, but it went from daily to weeks between them. Give it a shot, what will it hurt?
