Black Widow Spider Facts

Black widow spiders are venomous but because they only inject a small amount of venom, they are usually not dangerous, especially for adults. Most people are afraid of them, even though they will usually try to escape rather than bite.

The female sometimes eats the male after mating, giving rise to the nickname “widow”. The most easily recognized of the two is the female black widow. The black shiny body contrasts well with the red hourglass marks on her abdomen. The adult black widow males are about half the size of the female and have yellow and red spots and bands on their backs. The male’s legs are longer than the female’s and have a larger proportion of their body to them.

Black widow spider webs are often found near the ground (occasionally in dwellings), usually in the trash, rubble piles, or under or around homes, as well as outbuildings like sheds and garages. You can find them under eaves, under storage bins, beneath unused construction materials, and inside wooden toys, firewood boxes, and outdoor toilets. Black widow spiders are found under rocks, debris, plants, and other places where a web can be strung. These spiders may be driven into buildings by cold weather or drought.

The black widow female spider rarely leaves her web. Her web is made of coarse, irregularly woven silk. Depending on her needs, the same web can be rebuilt or modified continuously. The web is home to the female spider, where she spends most of her day. She can often be found upside down. The female catches her prey with her silk and wraps it around her body. The prey is then injected with venom after the silk has been wrapped around it. They can either eat the prey immediately or save it for later.

Black widow females stay close to their eggs mass and bite anything that might disturb them or their egg sacs. The egg sac is about 1/2 inch in length and oval in shape. They can hold 25 to 750 eggs and have an incubation time of 20 days. The first molts of newly hatched spiders will be predominantly white or yellowish-white. They gradually become more black as well as varying amounts of red and white. The female black widow stores the sperm and produces more egg sacs from just one mating. Female black widows have been known to live for more than 3 years.

If you are bitten by a black widow spider:

  • It may take some time to feel the bite.
  • A bite usually begins with small, local swelling.
  • Two small red spots may appear in the middle of the swelling.
  • Use soap and water to clean the area.
  • Use a cool compress to the bite. Keep the affected limb elevated above the heart.
  • Children under 5 years of age or adults suffering from severe symptoms may need to be treated in a hospital.
  • The bite will become more severe after three hours.
  • Common reactions include a general ache in the body and legs.
  • Other symptoms include dry-mouth and alternate salivation, paralysis of the diaphragm, excessive sweating, and swelling of the eyelids.
  • In extreme cases, headaches, high blood pressure, nausea, and sweating may occur.
  • The black widow’s poison can cause abdominal pain that is similar to appendicitis, as well as pain in the muscles and soles of your feet.
  • Most cases disappear within two to three days.
  • Calcium gluconate can be administered intravenously to treat muscle spasms caused by black widow venom.
  • A victim of a black-widow bite should immediately visit the doctor for treatment
