BLACK WIDOW SPIDER (L. hesperus) - ©NTI for the Daily Mail
Not uncommon in our neighborhood, but still surprised to find THREE of them decided to make a nest under my dish drainer this week - EEEEEEEK!
Sadly, the click through is to an article from 2008, reporting their expansion into the U.K.
- Black Widow spiders inhabit most of the warmer regions of the world to a latitude of about 45 degrees N. and S.
- They occur throughout all four deserts of the American Southwest.
- The female black widow spider is the most venomous spider in North America
- Her bite seldom causes death as it injects a very small amount of poison
- Reports indicate human mortality at well less than 1% from black widow spider bites. [A Black Widow bite did kill one of my cats several years ago]
- Anyone bitten by a black widow spider should seek medical care
- Cold weather and drought may drive these spiders into buildings —bingo!
- Adult male Black Widows wander in search of females but do not feed or bite.
- Females may occasionally kill and eat a male after mating but this is more the exception than the rule.
