Even though their is little danger of complications from spider bites, be advised that all spider bite victims should take the spider with them when consulting their physician. Under most conditions outdoors, spiders are considered beneficial because they feed on insects. However, they are undesirable to most homeowners when indoors, and the unsightly webbing spiders use to catch insect prey usually outweighs this beneficial behavior. Many spiders are associated with moisture and are found in basements crawl spaces, and other damp areas. Others live in warm, dry places so are found in subfloor air vents, in upper corners of rooms or in attics.
Most spiders hide in cracks, darkened areas, or areas where they can construct their web.
The Black Widows web is an irregular mass of fibers with a small central area which the spider waits until it's prey becomes trapped. They are usually found outside behind shrubs, along foundations, under boards, stones, and especially where wood siding or brick extends close to the ground. Black Widow spiders usually do not enter inside homes. The severity of a persons reaction to the bite depends on the area of the body where the bite occurs, the persons size and general sensitivety, the amount of venom injected, depth of bite, seasonal changes in venom potency, and temperature. The bite pruduces a sharp pain similar to a needle puncture.
