From Forum Garden:
"An article in the Daily Mail (UK) today, reported that the eight legged horrors are bigger this year, due to a mild winter last year, and a hot summer this year.
I always thought house spiders were big enough, so what size are they talking about? I'd dread to think!
The article in the Mail, however, seems to be praising the nasty critters! It concludes with 'If global warming means more, bigger and better-fed spiders, it is one consequence we should welcome. Bless their eight beautiful legs.' I don't think so! :("
Me, I don't mind too much, though I don't like spiders -- I know they are necessary and helpful critters -- just stay away from me!!
