Am I creating a wasp hazard?
Hello, I am thinking of capping the top of my double-lap wooden privacy fence with sheet metal. This would result in 4" x 4" x 3/4" cavities every six inches. (There would be about 500 cavities.) The cavities would be closed at the top and sides and open at the bottom. My questions are: Would wasps build nests in a cavity only 3/4" deep, and would I be creating some of kind of an insect nuisance for myself and my neighbors? What is the minimum size cavity wasps will build nests in? Thank you!

Thanks for the information. I don't know that anyone nearby has a medical issue with the wasps, however, the many wasps already in the area are good at getting in homes, which terrifies some people.
ONE MORE QUESTION. Someone has suggested that in the summer it might be too hot inside these thin gauge sheet metal caps for wasps to live there. Does that sound likely? (The fence is mostly unshaded.)
A picture of one test section of the fence cap is attached. The final design would be a little shorter in height and sections would overlap to cover the entire fence. Much of the void at top could be eliminated.
Sorry, I guess the photo is misleading. If you zoom in you may be able to see that every 6 inches there is a 4 inch gap in which the wasps can enter. The beards are overlapped, they are not edge-to-edge. Thanks.
I don't believe the 3/4" width would provide a large enough space for a suitable nesting site.
