But spiders have a number of other problems too. Firstly their looks, ugly buggers or what ? In history Ugly = Evil. It's common sense, if god is in everything beautifull & good then the devil is in everything ugly & bad. Their passion for sneaking up on people doesn't help either does it.
Myself I stopped killing spiders a long time ago so if you have more around you then you can blame me :-) I don't like them enough to invite them around for Sunday tea but I'm happy to share my space with them and even clean up after the buggers. Be nice to a spider today.
