I sprayed what I thought was a wasp with wasp spray and it didn't die?

Question

My shed is made of wood, and the sides there are cinder block at the base to keep from critters getting in. The inside of my shed is always getting wasps in it, I know this b/c they build these little paper honeycomb nests I spray and kill them with the wasp/horney spray. I believe they are wasps because they have those long dangling legs. Now on the side of my shed in the cracks between the cinder block I noticed another flying pest. It looks like a bee (solid yellow and furry like) but I am not sure. It could be a wasp but again I am not sure. I sprayed a could with the foamy spray and it didn't kill them. I sprayed the opening where they were flying in and out of and once the foam went away they kept flying in and out. Even the the cinder block still had the spray residue they were still flying and landing on it. What are these? Bees? Wasps? I am afraid to remove the block until it gets cold outside and I don't want to pay for removal. Does spray work on bees? Again didnt kill

Answer 1

This is a bad year for all kinds of wasps. I would get a pressure washer or just a hose end sprayer and look for their nest and knock it down if you can find it.
