Spiders get some bad publicity. These creepy insects move quickly without warning in any direction. They have sticky webs. Yet, almost all types of spiders do not pose a threat to humans.
Normal house spiders are the Common House Spider, Jumping spiders, and the Wolf Spider.
There are two species in the southern United States that can cause serious harm when disturbed: the black widow and the brown recluse spider.
Prevention
In any situation removing clutter and harborage sites would help prevent spiders in the home, garage and attics. Still they may come into your home, uninvited.
