They have been in my house this year, by the hundreds. They only seem to like my bedroom (it's on the west side of the house) and they come in one window. I have re-sealed and caulked, but they are still getting in. I take at least a dozen off of one window about 3 times a day. I am looking forward to freezing weather, but I figure we will still be killing them.
We use a pencil and flick them into a large cup with soapy water in it, then dump them down the toilet. That keeps them from releasing their "STINK" and it stinking up the place.
