Can yellow jackets build in the wall of a house and how do you kill them?

Answer 1

I'm from British Columbia, Canada and we have the odd year where we are over-run with yellow jackets. Yellow jackets hatch out in grassy areas so go to your local nursery and ask them what environmentally safe product you can put on your grass to safetly get rid of them. It's doubtful they do build in a wall of a house (they are hatched in the grass) but anything is possible. They are actually delicate in nature and like a daddy long legs. They are harmless, but nonetheless bothersome. Yellow jackets are ground dwelling stinging hornets that look like bees and are quick o attach whatever bothers them. They are far from harmless and can kill large animals if provoked. IF they are yellow jackets - I suggest getting expert advice ASAP. I have had yellow jackets do this exact thing, build in the wall of my house. Since they do not fly at night, you need to seal up the entrance they are using to get in and out. I used caulk for this purpose. They will starve to death rather quickly once they are sealed in. Are you sure you have yellowjackets. I had a similar problem, but they ended up being paper wasps. Yellowjackets are close in appearance to bees. Paper Wasps like walls, eaves of your home, etc. Easily identified by the honeycombed paper nest. Wasp sprays through holes and seal the entrance will get rid of them. Do a search for paper wasps for more info. Answer I have the same problem and they do appear to be Yellow Jackets. They are NOT paper wasps but they are in the wall behind my front porch light.
