I think they like to be near water, although not in it. I find them in the shower and also in the kitchen sink now and then. I capture them gently and carry them outside. All except for the thick-bodied black ones, to which I show no mercy.
Spiders are mostly good guys, and I try not to wreck their garden webs (we have a big one on the front porch right now), but I don’t go into their houses and I prefer not to have them in mine.
Ants are another matter. I have no tolerance for them whatsoever. It’s just one ant? Don’t tell me that. A single ant is a plague.
