How Common Are Black Widow Spiders?
WouterBlack widow spiders are the most venomous spiders in North America. They are commonly found in the southern United States and Canadian provinces.
They are most easily identified by the distinctive red hourglass markings on their abdomen. The venom is 15 times stronger than rattlesnake venom. It affects the central nervous system. It may cause a person to experience abdominal pain, nausea, cramping, and sweating.
Although black widow spiders are not aggressive, they can be an uncomfortable and irritating nuisance. They build webs in out-of-the-way areas. The best way to keep them away is to vacuum or sweep the area. You can also try smashing the web.
Black widow spiders are not only dangerous to humans, but to small dogs as well. The bite can be fatal to a dog, and it can also hurt a child or an elderly person.
The black widow spider is a common pest in homes. Their webs are commonly seen around porch lights and patio furniture. The female black widow spider is known to cannibalize the male after mating. The female spider has an egg sac that lays more than 200 eggs. The eggs are protected with silk. The venom is neurotoxic.
Black widows are also known for their ability to cannibalize smaller spiderlings. The black widows molt about six to nine times before becoming an adult. They can be mixed in colour and usually measure about half an inch in length. They can live for up to three years.
