Spiders are helpful outdoors because they eat many insect pests. Some spiders use webs to catch their prey, others chase and capture it. Most spiders are shy and harmless to humans. Although all spiders have venom, most cannot bite through human skin. However, a few can deliver very painful, poisonous bites, usually when cornered or agitated. If someone has been bitten by a spider, keep the person calm and contact the Poison Control center at 1-800-222-1222. If you would like help identifying the spiders in or around your home, you may consider contacting your local Cooperative Extension Service.
