Over the summer I noticed yellow jackets flying in and out of a little spot above a window in my house were the caulk had been worn away. I wasn't really concerned because I figured they were nesting behind the siding, but still outside of the house. In the last couple of weeks I have been finding many of them inside of my house, mostly in a bedroom which is located right above where I see them flying in and out. Everyday I usually find a couple of dead ones in my sinks as well. I didn't mind them living in my siding, but now that they are entering my house I am a bit concerned as I have two dogs (who eat insects) and a wife who has had a history of bad reactions to bee stings. Any suggestions on a humane way to deal with this? My wife is at the point where she wants to call an exterminator, but I'm definitely against that. Any suggestions would be great.
You could hire a professional to remove the siding and physically relocate the nest to somewhere else on your property (a hollow in a tree perhaps, or just anywhere where they have shelter form the elements)
I'm not sure if there is a cheap or inexpensive way to do this humanely, other than keeping your house really cold. But that can get expensive in the long run, and it doesn't really solve your problem; it just postpones the inevitable.
