Black Widow Spider Bite

Prevention

Because black widow spiders bite if they are disturbed, care should be taken in reaching into dark areas. This includes sitting down in an outhouse without first checking for other inhabitants. In areas where spider infestations are a problem, the use of a pest control service may also be useful.

Outlook

Complications in healthy adults are uncommon. If the black widow spider bite is not treated with antivenin, symptoms may last for several days but are seldom life threatening.
