Common Spiders in Houston

Spiders are an integral part of Houston’s natural ecosystem, contributing to pest control and maintaining balance in the local environment. Let’s take a closer look at some of the common spiders found in Houston:

Brown Recluse Spider

The Brown Recluse Spider, scientifically known as Loxosceles reclusa, is a venomous spider commonly found in Houston. It is recognizable by the distinctive dark brown violin-shaped marking on its cephalothorax. These spiders prefer dark and secluded areas, such as closets, attics, and basements. Although their venom can be harmful, Brown Recluse Spider bites are relatively rare and usually occur when the spider feels threatened.

Black Widow Spider

The Black Widow Spider (Latrodectus mactans) is another venomous spider species found in Houston. Females are easily identifiable by their shiny black bodies with a red hourglass-shaped marking on the abdomen. Male Black Widow Spiders are smaller and less venomous. These spiders tend to build their messy cobwebs in undisturbed areas like sheds, garages, and woodpiles. While their bites can be dangerous, fatalities are rare with prompt medical attention.

Garden Spider

The Garden Spider, also known as the Argiope aurantia, is a large and vibrant spider species commonly seen in gardens and fields throughout Houston. They have intricate yellow and black markings on their abdomens and build large orb webs to catch prey. These spiders are harmless to humans and play a crucial role in controlling the population of insects in the surrounding areas.

Wolf Spider

The Wolf Spider (Lycosidae) is a common sight in Houston’s outdoor spaces. They are robust and agile hunters known for their excellent eyesight. Wolf Spiders do not spin webs but instead chase and capture their prey. These spiders are usually brown or gray with various patterns on their bodies. While they may appear intimidating, Wolf Spiders pose no significant threat to humans.

Jumping Spider

The Jumping Spider (Salticidae) is a fascinating and colorful spider commonly found in Houston. With their excellent vision, these spiders can accurately judge distances and pounce on their prey with impressive agility. Jumping Spiders come in a variety of colors and patterns, making them visually striking. Unlike many other spiders, they do not rely on webs to catch their prey.
