I know what I would do if it were mine. (not telling you to do like wise)
I would make sure the LP was turned off and all lines emptied out. Just in case there was a leak. Which I don't have.
Then after it got good and dark out, I would get my little butane bottle with the torch on it. Get it fired up, open the door real easy. and point the flame at their comb/nest. it won't take much time or heat to burn the wings off them. Then just knock the nest out of there and step on them.
It doesn't take much to burn the wings off any bug that flies.
