Fumigation doesn't guarantee to get rid of huntsman or daddy long legs spiders - sorry hun, you'd be paying out big bucks and not solving the problem!

try natural alternatives (like the citrus that was recommended) - but don't go the chemical option - it simply doesn't work! we've seen a few around home (gets worse at change of season) - if DH is home, he will usher them outside (where they usually get nabbed by the birds) - if it's just me, i do what i can to move them out, but if i can't get to them, i will trap them and let DH deal with them when he gets home. i'm not a fan (after waking with one on my face as a kidlet) but i can't bring myself to resort to chemicals...
