they went through a little hole in my covered front porch. they even started a second nest nearby. I tried a spray bomb of foam for them, but that just foamed up around the hole where they are going in, then it dssipated by morning and it was a waste of 8 bucks. there is sort of a 8 inch thick wall and they are inside so I can't see where the nest is nest or the bomb would work. I think if I plug the hole they will find another way in.
I then came up with the crackpot idea that I might be able to heat up wood chips on a hotplate and ,using a computer fan blow smoke in there for a period of time, I started a prototype, but my smoke machine went up in smoke during it's initial test run out back. The fan melted and fell in the wood chips and they started a little fire on the hotplate, figured that would probably just make them subdued anyway, or someone might call the fire department. so that plan is out the window..
Now I am stewing over the idea of hooking up my shop vac with about 2 inches of water inside and sticking that by the hole where they fly out. maybe I could have them take a detour into the vac when they get up in the morning ? they seem to retire to the hive at night.
maybe I could spray something in there that they would hate the smell of ? I have a gallon can of really old old bolt loosener? I don't want to go ripping the porch apart, it is very old covered with cedar shingles. Where they are isn't really an exterior wall, I think the cavity is a bit big for expanding foam..
These little buggers are gettin the best of me. I hate going near them ever since I stepped on a nest as a kid. I thought maybe I could ignore them but they seem to be flocking to my front porch in ever increasing quantities .. ideas?
