Wolf Spiders in Rialto & Fontana — What Every Homeowner Needs to Know

You’re walking through your garage late at night and — out of the corner of your eye — something large and fast darts across the floor. No web. No warning. Just gone. Chances are, you’ve just encountered a wolf spider, one of the more intimidating pests in Southern California homes.

At TruPest Solutions, we’ve seen it all — and we know that ignoring wolf spiders can lead to bigger pest problems than you might think.

Why Wolf Spiders Shouldn’t Be Ignored

Wolf spiders aren’t looking to pick a fight, but if they feel cornered or threatened, they will bite. While their venom isn’t deadly, their bite can cause:

• Painful swelling and redness

• Itching or burning sensations

• Allergic reactions in sensitive individuals

The real danger? Wolf spiders are pest magnets. They go where the food is, which means if you’re seeing them, your home or yard probably has a healthy population of insects they’re hunting — crickets, roaches, ants, beetles, and more. In other words, wolf spiders might just be the visible tip of a much bigger pest problem.

Where Wolf Spiders Like to Hide

Wolf spiders are highly adaptable hunters. In Rialto and Fontana, we often find them in:

• Outdoors: Under rocks, firewood stacks, leaf piles, and thick mulch

• Indoors: Basements, garages, storage closets, and cluttered corners

• Transitional zones: Around doors, windows, and foundation cracks where insects slip in

They’re nocturnal, so you might not see them during the day — but you’ll often notice them scurrying across floors, patios, or driveways after dark.

What Wolf Spiders Eat (and Why That Matters)

Wolf spiders don’t spin webs to catch food — they stalk and pounce. Their diet in the Rialto and Fontana area includes:

• Crickets

• Ants

• Grasshoppers

• Beetles

• Cockroaches

While this might sound like free pest control, it’s actually a red flag. A yard or home full of insects means a steady buffet for wolf spiders, and without treatment, the population of both will keep growing.
