I know a lot of folks find wasps when they buy a truck. I was driving my 1969 3/4t panel home from Charlotte NC to Raleigh NC when I opened the drivers side floor vent. Out came the little buzzers ALIVE! They seemed woozie and I shut the vent and pulled off the road in a hurry. I stomped and brushed with a rag until I had them out and drove the rest of the way home with hot but unstung feet! I gave the remaining wasps a good shot of wasp spray when I got home and vacuumed out the bodies later.

Best wishes and Merry Christmas,

Les
