I've tried conkers, they didn't work, I bought an electronic thingy off the internet (£30) and it seemed to work for a while but I saw a spider actually making a web dangling from it the other day! I've tried sprays, jars and jumping on them but nothing seems to work, then I acquired a cat, and there is nothing he likes better than a nice spidery hors d'oeuvre before a meal, just need him to be in at the right time.
I live alone so I have no DH to deal with the pesky things and although last year I managed to handle a tarantula at a petting zoo I am still irrationally afraid of our native species. I think it's because tarantulas move slowly whereas all the others seem to scuttle furtively so that they actually look like they are up to mischief.
