I have a wasp problem. They have found a way into the boxing of my house under the overhang, behind the gutters. I can see them entering and exiting at 2 points. Both are very small cracks. I have sprayed an entire can of wasp killer at the cracks. I killed some, but still see many more. I even Wyatt Earped a few....knocking them out of the air with the spray as they were attacking me.
Being allergic to their stings, I really can't get "close" and spray the daylights out of them. I also have no idea how many I am dealing with. Maybe tens, maybe hundreds.
Any suggestions?
