Anyone else have 'em? I've had an annual infestation here in SW Portland since I bought this place over a decade ago, some years worse than others. In the past, Dawn dish soap spray outside helped a little. And I did some serious caulking around a couple drafty window frames, which helped a lot. Will repeat both processes again tomorrow as this is the worst year by far. Usually gone by mid-December, they just kept multiplying this winter. This afternoon I came home to a swarm of hundreds in a room on the sunny end of the house. I called an exterminator one year and he basically said he wouldn't do business with me. Said I'd be pissed off and demanding my money back when they reappeared (not if) - he doesn't know of any lasting treatment. In fact, he's the guy who hipped me to the Dawn dishsoap idea. So besides Dawn and caulking, any other techniques you guys recommend?
