Wasps contained by my garage-can I catch close to the nest contained by winter weather w/o protection? I discovered yellowjackets in my garage this summer but be never able...

I discovered yellowjackets in my garage this summer but be never able to find the nest. I deduce it might be in the wall. It's winter here surrounded by WI, so I was wondering if I needed to verbs about them swarming me if I try to find and remove it in a minute?
Why my hopt sea doesn't run?
Answers:    You bet you can get rid of them contained by the winter. Wasps will be dormant anytime the temperature drops below 40 degree. Grab the nest, and toss it. Better yet, burn it.
Is it still risk-free to use an appliance...
Call your local exterminator and ask. The best piece of it is that the call is free and you'd be getting proposal from a professional!!
