Spiders in the Home

Spiders are predatory arthropods of insects. Unlike the horror movies, spiders do not attack humans unless provoked to bite by handling, whether intentionally or not. All spiders have 2 body regions like ticks: an unsegmented abdomen and a cephalothorax. Unlike ticks, a spider's abdomen is constricted at the base, but, like ticks, spiders have 8 legs and no antennae. So, if your bug has 8 legs and a constricted abdomen, it's a spider.

Spiders of Little Concern

These spiders pose no serious health risk to people, although a few people do have an allergic reaction to their accidental bites.
