Spider Control

Many "poisonous" house and garden spiders pose no threat to people because they have mild venom, or fangs too small to break human skin.

Others, including most tarantulas sold as pets, deliver bites that result in moderate pain and swelling, comparable to bee stings.

Some people have severe allergic reactions, however. To eliminate risk, wisely avoid handling any spider.

Highly venomous species, such as black widows and brown recluses, cause illness and death; avoid trying to make these spiders into pets.
