Most spiders are small, inconspicuous arthropods which are harmless to
humans. Very few of the nearly 900 species of spiders in Alabama can hurt
people. Only two groups--recluse spiders and widow spiders-- are considered
poisonous to humans.
Tarantulas, jumping spiders, wolf spiders and some other spiders worry people
who mistakenly believe they are seriously poisonous. Although these spiders are
often large, hairy and formidable-looking, their bite is typically less harmful
than a bee sting. People who are extremely allergic to spider venom, though,
react severely to any spider bite.
Many people have a phobia of spiders. However, knowing how to distinguish
harmless from dangerous spiders, how to prevent them from entering the home and
how to control those that do enter can prevent needless concern and reduce the
chances of harm to humans.
Relieve local swelling and pain by applying an ice pack, ammonia or alcohol
directly to the bite area. In case of severe reaction, consult a doctor
immediately and, if possible, take along the spider for positive identification.
Specific antivenin is available to treat some widow spider bites.
