Personally, spiders don't bother me a bit. Roaches, on the other hand...... -=shudder=- I know, I know, roaches don't bite, spiders do, but... Roaches are just GROSS. And spiders are cute and hairy and only eat other insects.

I'm with you on this. Spotting a roach inside would literallycause me to move. Literally. Because if you see one... you've got a million in your walls.
(Pardon the MadTV reference.)

Spiders, on the other hand, experience unique evolutionary pressures in my household. I kill the big ugly hairy ones and let the cute little ones be. After a few years of this, I only have cute little spiders who I trust to keep all the other insects under control.

By the way, anyone else remember a children's book called "Be Nice to Spiders" which exhorted you leave them alone because they are good to have around?
