Today I noticed a couple of yellow jacket bees in the Master bedroom where I have a small woodstove installed. I can't figure out how they got in. I'm wondering if they could possibly be coming down through the chimney (or making a nest there!)? Groan! If so, what's the best way to handle this? I thought of starting a fire but then I was afraid it might start a chimney fire if there happens to be a nest in there. Any suggestions would be appreciated. While we're on the topic if it turns out they're not coming down the chimney (or making a nest in it) is there any way to prevent this from happening in the first place?
