I do that, Boxy. There's one in my shower room at the moment. I keep rescuing it from the shower tray. It seems to like that area. There are obviously lots of insects in there for it to eat.....................?
At the bottom of the stairs this morning there was a massive spider on the wall. I'm not frighten of them so when I say massive I mean it. I put a pint glass over it and a post card across the wall and when it was in the glass took it outside. Thinking it may return I took it about 50 yards away.
