If you see a large, hairy spider scurrying across your garage floor at night, it is likely a Wolf Spider. While their size and speed can be alarming, they are actually beneficial hunters that keep other pest populations in check.
The Wolf spider is unique because it doesn't use a web to catch its dinner; it relies on pure athleticism.
The PounceLike a wolf, they hunt. They sit in wait and pounce on crickets, beetles, and even other spiders.
Maternal InstinctYou might see a Wolf spider that looks "extra fuzzy." This is likely a mother carrying her egg sac on her rear, or her hundreds of hatched "spiderlings" on her back.
The Basement ResidentBecause they are ground hunters, they love the cool, dark floors of Utah basements. They often enter through the garage or through gaps in the foundation.
Do they bite?Only if provoked or squished. While physically painful due to their size, their venom is not dangerous to humans.
Why are they in my house?They are often "accidental" guests who follow prey (like crickets) inside. They don't want to be in your living room, but they find Utah basements very comfortable.
Are they attracted to light?No, but the insects they eat (moths and flies) are. You will often find Wolf spiders near porch lights or glass sliding doors because that is where the food is.
