Black Widow Control

black widowHow do I know the spider in my house is a Black Widow?

Not all adult black widows exhibit the red hourglass on the ventrum underside or top of the abdomen — some may have a pair of red spots or have no marking at all. Female black widows often exhibit various red markings on the dorsal or top side of the abdomen, commonly two red spots. However, black widow young are believed to have at least some sort of marking on their abdomens. Adult male black widows are half the size of the females, and are usually gray or brown rather than black and red; while they may sometimes have an hourglass marking on their ventral abdomen, it is usually yellow or white, not red. Variation in specifics by species and by gender is great; any spider exhibiting a red hourglass or a pair of large red round spots on the ventral abdomen with an otherwise black shiny body is an adult female black widow. The bright red hourglass and spots are never located on the dorsum, which is the more visible aspect; the identifying features are on the underside, anatomically known as ventrum; i.e., the spider must be lying on its back to reveal the markings.

Nowadays a lot of people have heard about the black widow, mainly thanks to Scarlett Johansson Black Widow. Keep in mind they’re both really dangerous.

Facts about Black Widow:

  • Their deadly poison is said to be 15 times stronger than rattlesnake venom.
  • Black widows use a silk-like substance to weave tangled-looking webs, typically close to the ground in covered or dark places, such as near drain pipes or under logs.
  • The tips of the black widow’s legs are coated with an oily substance that prevents the black widow from getting caught in its own web.
  • The female black widow lays approximately 200 eggs. The eggs incubate for some 20 days in a small, round papery sac that’s attached to the mother’s web.
  • The name “black widow” comes from the female’s habit of eating the male after mating.
  • While the black widow’s poison is rarely fatal to humans, it can cause severe pain and nausea.
