We've not experienced the "swarms"....just the pesky things clinging to the windows. I'd not fret or panic over them as they don't seem to do anything nasty. We've not seen them flying around in the house at all. Haven't seen what the originator of this thread has experienced. We are in FL (semi-tropical) and there are all sorts of critters we haven't seen "up north". Exterminators are a must!!! Good luck in getting rid of these in your home!!!
