Last night we killed 14 yellow jackets inside the house. They had found a way in at a sliding glass door, but even after we shored up their entry point, they persisted. Trying not to use poison...employing many measures right now that include wasp traps, borax, and maybe fish or liver over a bucket of soapy water.
I think the snakes were more agreeable to me than having wasps invade the inside of my house. Mr. Nature was stung again last night while killing the swarm.
