Yeah, they usually just kind of mind their business and leave once a window is open. The whole prospect of having to go to the doctor and lose work time/fun time/learning time is what bothers me. That and of course my family's safety. I am going to have to look into to epi-pens. I am not allergic to bees that I know of (have been stung many, many times), but I am not sure about Isaiah and Miyuki.
