Oh wow, I hate any kind of bugs getting in the house, but yeah... wasps feel scary, even if they don't mean any harm. And, I don't know a good way to get them back outside without hurting them (sorry, wasps!)

I had one get in once. I vacuumed it. And, it got out again (if I remember correctly).

I think I had to vacuum it again, then take the vacuum out in a back room that is not part of my main house, and leave it out there for awhile.

I wish they'd create a vacuum cleaner that can act like a normal vacuum, but also have some special "eliminate the bug" mode, so that they can't come back out. My new one might work out... I think the bags have a little plastic seal that opens from the suction when it's turned on, but closes when you turn off the vacuum. It might do a better job of trapping the critters, but I'm not sure.
