Black widow spiders are most recognized for the red hourglass shape
on the back. Contrary to legend, female black widow spiders rarely
devour the male black widow spider after mating. Black Widow Spiders
can be found in All 50 States.
Habits
Black widow spiders spin their webs near ground level. They often
build their webs in protected areas, such as in boxes and in firewood.
Habitat
Black widow spiders are often found around wood piles and gain entry
into a structure when firewood is carried into a building. They
are also found under eaves, in boxes, and other areas where they
are undisturbed.
Threats
The venom of a black widow spider is a neurotoxin and is used as
a defense. Black widow spiders do not bite humans instinctively.
The black widow spider bite can cause severe pain. Young children
and the elderly are especially susceptible to a severe reaction
to a black widow spider bite.
Prevention
Avoid black widow spider bites by wearing heavy gloves when moving
items that have been stored for a long period of time. Spiders often
hide in shoes, so check shoes and shake them out before wearing.
When spider webs are visible, use caution before putting your hands
or feet in that area.
