COMMON ARIZONA PESTS
Black Widow Spider
These spiders get their common name from
the popular belief that the female eats the male after mating, a
phenomenon which rarely happens in nature. Female is glossy
black, with a red hourglass on the underside. Males are much
smaller and are gray in color with stripes or spots. They are
found in rock crevices, wood piles, overhangs, dark garages,
basements, stables, and abandoned rodent holes. Spins an
irregular web of silk strands, which are heavy and strong.
This spider is not an insect but a predatory arachnid that feed
on insects. Highly venomous – a bite can be, but rarely is
fatal. The black widow’s neurotoxic venom affects the nervous
system. In humans, a bite can cause systematic pain, nausea,
muscle spasms, and respiratory paralysis. There is no first aid
procedure for bites. Consult a physician immediately.
