Trying to deal with a wasp nest, that is inside a wall, without cutting a hole in said wall. I doubt we will be successful, but I really don't have the extra moolah for an exterminator. Frickin stupid wasps. Ya got a forest full of trees and stumps and shit, stay outta my house!
(100% sure they are wasps and not bees)
@Evereigh Localize the nest. Drill a small hole a foot or so from the top, assuming it doesn't go to the top, and spray insecticide with a small nozzle or hose, if possible. Downside: fumes and toxic chemicals.
Alternative solution: Again, drill a small hole in the sheetrock and pump in CO2. Be sure to seal all cracks so 1) the wasps can't leave and 2) so the gas will remain in place long enough to suffocate them. Be especially sure you, yourself, have adequate ventilation.

@Evereigh You're more than welcome. 😊
