Poisonous Spiders and Black Widow Spiders

Almost all spiders are venomous. However, there are some spiders that are notorious for the toxicity of their venom. These U.S. species include the brown recluse and the black widow. Spiders are capable of administering bites with their fangs, which are designed to catch prey and devour food. Fangs are also used in self-defense, at which time poisonous spiders inject venom into the flesh of the victim.

Are Black Widow Spiders Poisonous?
The black widow spider delivers the most toxic spider bite in the United States. Black widows are most prevalent in warm, southern areas, although they have been identified as far north as Canada. The black widow spider’s venom is a neurotoxin.

Brown Recluse Spiders
Brown recluse spiders administer venom that can cause severe tissue damage. Also known as the violin or fiddle-back spider, the brown recluse is easily identified by a violin-shaped design on its back which must be coupled with having three pairs of eyes. Like black widows, brown recluse spiders tend to dwell in dark, remote locations. Caution should be used when cleaning or even reaching into dark, infrequently visited places.

If you suspect that one of these spiders has bitten you, seek a medical professional. Try to take the spider along to the medical facility for proper identification.
