The Southern House Spider, also known as the Southern Black Widow, is a species of spider that is native to the southeastern United States. These spiders are known for their distinctive black body with a red hourglass shape on their abdomen, and are considered to be one of the most venomous spiders in North America.
Despite their fearsome reputation, Southern House Spiders are generally not aggressive and will only bite humans in self-defense. Their venom is a powerful neurotoxin that can cause severe pain, muscle cramps, and breathing difficulties, but it is rarely life-threatening.
Southern House Spiders are found throughout the southeastern United States, and are commonly found in homes, basements, and other dark, secluded areas. They are nocturnal, meaning they are most active at night, and are skilled at hiding in small spaces and avoiding detection.
One of the most interesting things about Southern House Spiders is their unique web-spinning behavior. These spiders spin a characteristic “cobweb” style web, which is made up of a series of sticky threads that are designed to catch prey. The web is typically spun in a corner or along a wall, and the spider will often decorate it with a series of white, silk threads that reflect light and help to attract prey.
In addition to their venom and web-spinning abilities, Southern House Spiders are also known for their complex social behavior. Female Southern House Spiders are known to be highly territorial, and will often fight with other females to defend their web and territory. Males, on the other hand, are generally smaller and more docile, and will often wander in search of females to mate with.

Life Cycle of Southern House Spiders
Southern House Spiders undergo a complex life cycle that involves several different stages. The female spider will typically lay a sac of eggs in the spring or summer, which will hatch into tiny spiderlings after several weeks. The spiderlings will then disperse and start their own webs, eventually growing into mature spiders.
The life cycle of a Southern House Spider can be broken down into the following stages:
- Egg sac: The female spider lays a sac of eggs that can contain up to 900 individual eggs.
- Spiderlings: The eggs hatch into tiny spiderlings that are about 1⁄16 inch (1.5 mm) in length.
- Juveniles: The spiderlings grow and molt several times, eventually reaching a length of about 1⁄4 inch (6-8 mm).
- Adults: The juveniles reach maturity and start spinning their own webs, eventually mating and starting the cycle over again.
Fun Facts About Southern House Spiders
- Southern House Spiders are related to the Black Widow spider: Both species belong to the same genus (Latrodectus) and are known for their venomous bite.
- Southern House Spiders can live for up to 3 years: This is unusually long-lived for a spider, and allows them to establish complex webs and territories.
- Southern House Spiders are important predators: They help to control insect populations and can be an important part of the ecosystem.
