As I posted in another question, I had wasps entering my fireplace exhaust in my backyard. When I turned the fireplace on, I got a distinct burning smell; and then it went away.
Then I saw them crawling into a small space between two bricks in my front overhang. So I sealed it up with silicon. The next day, I saw a dead wasp there.
Now, I have a feeling (not 100% sure) that I saw a wasp fly into that front overhang area, and not fly out. I'm concerned that there's a wasp nest, and that they're not dead yet.
How can I find out for sure? Do I need to call a professional? (I looked everywhere in my house, but I couldn't find any signs of them.)
And, how do I find their new entrance to the nest, if there is one and there is a nest?

I would buy a lot of wasp spray and and spray it all around the overhang area. You might eventually start seeing dead wasps in one general area and be able to find the entrance that way. Of course, you may need to wait until summer since it's winter time now.
