Don't like 'em, to put it mildly.
The last few years, I've kept ahead of them with pre-emptive application of poison
around the foundation. This spring they got the jump on me, and established a beachhead in the attic, from which they were dropping through a tiny crack in the ceiling tiles onto the HEAD OF MY BED. Stopped that with caulking, but they will undoubtedly find another way to torment me. Hoping the insecticide will help this time.... surely they have to go outside at some point.
To top it all off, Ward Churchill is here in Spokane today.
Bad day at Dry Gulch.
[Much later: These were not ants, they were termites. That's why they didn't go outside. Finally had them exterminated in 2008. Ashamed that I didn't figure it out earlier, didn't stop to ask what's wrong with this picture.]
