Oh my, Aloha - 20 nests?! I've wondered if we might get them in our attic, too, as late last summer a piece of our vinyl siding fell off of the roof edge. We haven't put it back on yet as it's all the way to the top and we'll need a really tall ladder to get up there. We may have to hire someone for that job - neither one of us wants to, or should be, on a ladder that tall! I know what you mean, Skybird, about seeing old nests around and yet still see the wasps. Maybe they were their old nests?! I don't know. And I also thought that one fake nest looked like a chinese lantern - it's the same kind of fabric and wire frame. Also, you can't see it in the pic, but it has a hole in the side so it looks like a nest of sorts. But I kinda of wonder if the wasps would just go inside of it and make a nest of their own there! I know they did that in the bird houses I put up along our fence for decoration - I had to plug up the holes so they wouldn't do that any more. So I couldn't resist making my own version of the fake wasp nest, just to see if the concept would work. I recycled/upcycled items I had around the house already to make it - took two 5" peat pots and placed them together at the large end, then slipped a plastic mesh wrap (that they put over the glass bottle of wine I bought at Total Beverage) over them to hold them together, then glued the seam. I spray painted it black, but didn't like the looks of it. So I covered it all with paper mache, I then spray painted it black with a little gray. Now, it's not any prettier than the waspinator, and maybe even a bit uglier, but didn't really cost me anything to make! Maybe this is close enough in shape to fool the foolish wasps - we'll see! If it does, I'll make some more!! Here's my recycled/upcycled wasp nest decoy:

brendalynnsoer_shaw_ca, I have the exact same problem. There is a small bit of stucco broken away where the eavestrough (gutter) attaches to the side of the house. The wasps access their nest via that hole in the exterior wall. I imagine the nest is in the soffit. Somehow from there they can get into the bedroom below the soffit. I had the window company come out to see if they were getting in through the window, but the serviceman checked and said no. There is expandable foam all around the window so no wee chinks or holes for them to get in. For the life of me I can't figure out how they're getting in. It is the last week of October here in Edmonton, Alberta and it's getting pretty chilly out at night. We've had a couple of good hard frosts lately, but that doesn't seem to be impeding the wasps' access to the bedroom. I'm afraid the queen will overwinter in the nest. Given the heat that comes off from the house they may not die due to the cold. They may just become dormant. I dunno! I was going to get the hole closed off but now I'm afraid to, considering what you went through. What to do? What to do???

I hate to say it, Martha, but I would spray it. They do sting and they kill caterpillars in large numbers. In one sense the choice is more wasps or more caterpillars. I have seen these wasps kill very large caterpillars. It isn't pretty seeing what happens. (I won't describe it.) I try very hard not to kill anything in the garden. I don't kill cockroaches or pretty much any other insects other than fire ants and wasps. A wasp really hurt my dog--stung her in the nose. I have friends and relatives who are allergic to wasp bites. My brother had a severe allergic reaction after a bite. The people at the hospital said it could have been life-threatening had he not been take there very soon afterwards. In his case the wasp got tangled up in his hair and stung him as he was trying to get it out. No doubt these wasps serve a purpose in the natural order of things. You are presenting them with a banquet of eggs and caterpillars. I'm sure they really like your garden. I do respect your opinion and that of others to not kill them. I simply have another point of view.

Baldfaced Hornet. I wouldn't advise that anyone try to remove a nest themself; the risk for an attack is great unless you know exactly what you're doing. On the other hand, it might not pose a risk at all, depending on if the nest is located away from activity or not. Do some Googling to read about these insects so that you can make an informed and safe decision.
