Black Widow Spider

Black Widows be gone!

The black widow spider gets its name from the popular belief that the female black widow spider eats the male after mating… but this rarely happens. That said, you should not consume a black widow spider! – not that its your intention too – as they are poisonous within the first 17 days of their life.

Black widows are active in room temperature conditions or higher, but can still survive in lower temperatures. They spin nonuniform webs at night close to the ground, and hang upside down from them.

Females can be aggressive, especially when guarding their eggs, and may bite in defence. The bite is unlikely to be fatal, as long as proper medical treatment is sought in a timely manner. Symptoms may include: fever, sweating, nausea, and increased blood pressure. For more on black widows, click here.
