We stood outside a house, trying to figure out where the wasps were coming from. As we talked, a wasp landed on the wall in front of us, and crawled up under a sheet of plastic that had been nailed to the wall to keep the rain out. I squished it through the plastic using a weird metal implement I held in my hand, like a door handle. When I did that it moved the plastic closer to the wall and I saw a couple more wasps under the plastic further up, so I squished those too. That revealed a dark spot under the plastic, which was the wasp nest. It was the size of a basketball. I could see the blurry blobs of hundreds of wasps under the plastic starting to move around, so I frantically started running my implement back and forth over the plastic to squish them all, and the nest.
