Seeing a wolf spider dash across your floor can be an unpleasant surprise. These fast-moving, hairy spiders are active hunters that typically live outdoors but may wander inside homes while searching for prey or shelter.
If you’ve spotted a wolf spider indoors, the most effective approach is to address the conditions attracting them such as other insects, outdoor hiding places, and gaps around the home rather than simply killing the spider you see.
So, how do you get rid of wolf spiders and keep them from coming back? The key is to combine indoor pest control, entry-point exclusion, and outdoor habitat management.
What Causes Wolf Spiders to Enter Your Home?
Wolf spiders typically live outdoors and hunt on the ground, under rocks, vegetation, and other sheltered areas. They may occasionally enter homes while searching for prey or shelter, particularly through gaps and openings around the building.
Common entry points include:
- Cracks in foundations
- Gaps around doors and windows
- Vents and utility openings
- Openings around pipes and other penetrations
Inside a home, wolf spiders may be found in garages, basements, storage areas, closets, and other quiet spaces.
Steps to Get Rid of Wolf Spiders Quickly
Find Their Hiding Spot
Use a flashlight to inspect baseboards, cluttered corners, closets, and utility rooms. Look for live spiders, shed skins, or egg sacs. They don’t spin webs to catch food, so you won’t find obvious signs.
Cut Off Their Food Supply
Wolf spiders eat small bugs like roaches, ants, and silverfish. If those pests are present, the spiders will stay. Set sticky traps, use insect growth regulators, and vacuum regularly to eliminate insect activity.
Use Targeted Insecticides
Contact sprays do little. Instead, apply:
- Residual insecticides along the baseboard.
- Pyrethroid dust in wall voids and outlets.
- Perimeter sprays outside doors and windows.
Always follow label instructions or call a licensed pest control pro.
Seal Every Entry Point
A gap the size of a pen is enough for a wolf spider to slip through. Seal cracks in concrete, gaps around utility pipes, and install door sweeps. Check at night: if light comes through, so can spiders.
Fix Outdoor Conditions
Wolf spiders migrate from outside. Clear leaf piles, store firewood away from the house, and trim back bushes. In Texas, watch for the Carolina Wolf Spider, which is the largest of its kind. These spiders often burrow in soft soil near buildings.
Wolf Spider vs. Brown Recluse: How Can You Tell the Difference?
Wolf spiders and brown recluse spiders can sometimes be confused, but they have important differences. Texas A&M AgriLife Extension notes that wolf spiders typically have dark stripes on the body, lack the brown recluse’s fiddle-shaped marking, and have a prominent pair of eyes on top of the head.
Key differences include:
- Wolf spiders: Usually larger, hairy, fast-moving hunting spiders with prominent eyes. They do not build webs to capture prey.
- Brown recluse spiders: Usually smaller and brown, with a characteristic violin-shaped marking and six eyes arranged in three pairs. They prefer undisturbed areas and are primarily active at night.
Wolf spiders are not considered dangerous to people, while brown recluse spiders are venomous and can cause medically significant bites. However, identifying a spider from a bite or a quick glimpse can be difficult.
If you are unsure what type of spider you have found, avoid handling it and consider having the spider professionally identified.
Final Words
If you want to get rid of wolf spiders and reduce the chances of them returning, focus on the conditions around your home that can attract or shelter them. That includes reducing other insect activity, sealing entry points, keeping outdoor areas clear of debris, and addressing potential hiding places.
If the problem continues or you’re dealing with recurring spider activity, professional pest control can help identify where spiders are entering and what conditions may be contributing to the problem.

Frequently Asked Questions About Wolf Spiders
Are wolf spiders dangerous to people?
Wolf spiders are not generally considered dangerous to people. They may bite if handled or threatened, but their bites typically cause localized pain, redness, or swelling rather than serious medical problems.
Why am I finding wolf spiders inside my house?
Wolf spiders normally live outdoors but may enter homes through cracks, gaps around doors and windows, vents, and other openings. Indoor spider activity can also be associated with the presence of insects that serve as their prey.
How do I get rid of wolf spiders naturally?
Start by removing clutter and outdoor debris, sealing cracks and entry points, reducing standing water and moisture where possible, and addressing other insect pests around your home. These steps can make your property less attractive to wolf spiders.
Do wolf spiders come back after pest control?
Wolf spiders can return if they continue to have access to outdoor shelter, prey, or entry points into the home. Sealing openings and reducing conditions that attract insects can help reduce recurring spider activity.
What is the fastest way to get rid of wolf spiders?
For an occasional spider, removing it safely and sealing nearby entry points may be enough. If you are seeing wolf spiders repeatedly, identifying and addressing the source of the activity—including other pests and outdoor hiding areas—is more effective than treating individual spiders.
How can I tell a wolf spider from a brown recluse?
Wolf spiders are generally larger, hairy, and active hunters with prominent eyes. Brown recluse spiders are usually smaller and brown, with a characteristic violin-shaped marking and six eyes arranged in three pairs. If you cannot confidently identify a spider, avoid handling it and consider professional identification.
