General Information

Spiders are almost always unwelcome guests in the home, but perhaps none more so than the wolf spider. This large, hairy, quick-moving arachnid is found throughout the United States, and the world, and loves to sneak up and scare people in their homes. Learn about these unusual spiders, how to identify them, where they live, and how to get rid of them in your home.

What Are Wolf Spiders?

Many people fear wolf spiders, and they don’t seem to look or act like other spiders out there. Unlike the majority of their brethren, wolf spiders don’t spin webs to catch prey. Instead, they hunt insects (like the wolves for which they’re named), using their excellent eyesight and superior speed. Wolf spiders are part of the Lycosidae family. There are over 2,300 various species of wolf spiders, 200 of which live in the United States.

While they’re terrifying for smaller arachnids, they really pose little threat to humans. They might bite if provoked, but for the most part, they focus on hunting for food.

What Do Wolf Spiders Look Like?

Wolf spiders have a very distinct appearance. They are most often confused with tarantulas, but they have multiple distinguishing characteristics that set them apart. They are very hairy and have distinct markings on their backs that some people say look like the British flag.

Each spider has eight eyes, which are prominent and often seem to glow in the dark. They have eight legs, like all spiders, which have bands the same color as the markings on their backs. They can range in size from a half-inch to over two inches in size depending on the specifics of their genus and species.

Where Do Wolf Spiders Live?

Wolf spiders live all over the world, including in the United States. While their landscape preferences include flat, grassy areas, like meadows and grasslands, wolf spiders are very adaptable and can live in nearly every type of landscape, including deserts, rainforests, and mountains. They do prefer warmth, so people tend to find wolf spiders indoors when the weather turns cooler.

Problems With Wolf Spiders

Wolf spiders can bite when they feel scared or threatened. While they are venomous, their bites won’t do lasting damage. Most people experience some itching and swelling that resolves within a few days. Despite this, wolf spider bites are not ideal, so it’s best to keep them out of your home whenever possible.

Then, consider calling a professional pest control company to help eliminate the wolf spider population in your house and any other insects that may be there as well.

Keep exterior landscaping trimmed and away from the structure of the house. Any lawn waste or supplies like firewood should be kept off the ground and at least 5 feet away from the walls of your home.
