I've found a few other things that kill them too. Unfortuneately, when you have thousands and thousands of them swarming around your house and trying to get in, or at least behind the vinyl siding, it seems pointless to try and kill them all. I'm wondering if anyone knows of anything they truly "don't like", and that would repel them. It would be OK if it killed them too, but mostly, I'd just like to keep them away.
