I know my greenhouse is infested with small spiders, I think they love the
warmth. However you only really notice them when disturbing the gravel
bed,
or when you place a large plastic sided tray in there, since they then
fall
in it and have trouble getting out again. It's not just that is it ?

Probably. That's why you find spiders in the bath. Nothing to do with
climbing up the plughole - they fall in and can't get out again.
