Hey, I’m not touting nothin’. that would be unprofessional.
all I can say is that they’ve worked for me. we had a big wasp nest several years running under our porch, and nothing worked to get rid of it. then we tried the fake wasp nest by the porch and haven’t had wasps since.
we’ve since put them in our back yard as well. results haven’t been as dramatic there, because of the size of the yard, but we’ve definitely noticed an improvement.
I dunno, maybe wasps in Canada are just gullible or something.
