My new place has these little bug things that are called silverfish...http://en.wikipedia.org/wiki/Silverfish
if you don't know what they are. As far as being a tangible pest-they don't bite humans, eat wood, hurt the cat, etc....so really they are any pest ridden persons least nightmare.
But they are gross! And everywhere. I've been reading that they like moisture. I live in the northwest so this doesn't surprise me. Anyone ever encounter them or know what to do with them?
