The Black Widow's Tangled Rep

Often illusive, black widow spiders are some of L.A.’s most misunderstood animals. A few truths:

1. Black widows eat a wide variety of prey, from small insects to vertebrates such as lizards, snakes, and small mammals. 

2. They are venomous, but not aggressive and rarely bite unless they are pinched or squished.

3. Rule of thumb—safety first! Don't reach your hands into spaces that you can't see.

4. They like to hide away in crevices and holes during the day, but they will be more exposed at night, often hanging upside-down in their webs. While it is possible for the occasional widow spider to come indoors, they much prefer to be outside.
