How to Keep Wolf Spiders Out of Your House

I’ve always been fascinated by the wonders of nature, but one creature that I’d rather admire from a distance is a wolf spider. These eight-legged arachnids may be harmless to humans, but their sudden appearances in my house still give me quite a scare. That’s why I’ve spent countless hours researching and experimenting with various methods to keep these creepy crawlers out of my living space. In this article, I’ll share with you some effective tips and tricks on how to keep wolf spiders at bay, ensuring a peaceful and spider-free environment in your home.

Identifying Wolf Spiders

Physical characteristics

Wolf spiders are easily recognizable due to their unique physical characteristics. They are typically medium to large-sized spiders, ranging from 0.4 to 1.4 inches in length. One of their distinguishing features is their two large, forward-facing eyes, which give them excellent vision. They have a stocky and robust body, covered in hair, usually brown or gray in color, with various patterns and markings, allowing them to blend in with their surroundings. Another characteristic is their eight long and agile legs that enable them to run quickly.

Behavioral traits

Wolf spiders are known for their hunting abilities and active nature. Unlike most spiders that weave webs to catch their prey, these spiders rely on their excellent eyesight and agility to chase and capture their victims. They stalk their prey, often pouncing on it when it least expects it. They are also solitary creatures, preferring to live and hunt alone rather than in groups. They are primarily nocturnal, becoming more active during the night and seeking shelter during the day.

Typical habitats

Wolf spiders can be found worldwide, except in extreme cold regions. They prefer a wide range of habitats, including grasslands, forests, deserts, and even urban areas. These adaptable creatures can be encountered both indoors and outdoors. In natural environments, they inhabit burrows or construct silk-lined retreats in leaf litter or underneath rocks. When they enter homes, they often seek shelter in dark and undisturbed areas like basements, garages, and attics.

Understanding What Attracts Wolf Spiders

Well-lit areas

Wolf spiders are primarily attracted to well-lit areas, especially during the night. They are drawn to lights around entry points such as doors and windows. Bright indoor or outdoor lighting can serve as a beacon, drawing these spiders towards your home. Cutting down on excessive or unnecessary lighting can help reduce their attraction.

Food sources

Like most spiders, wolf spiders are attracted to places where they can find an abundance of food. Common prey for wolf spiders includes insects like beetles, crickets, and ants. If your property has an abundance of insects, it will likely attract wolf spiders. Regular pest control measures to minimize the presence of their prey can help discourage these spiders from entering your home.

Moisture and humid conditions

Wolf spiders are also drawn to moisture and humid conditions. They prefer damp areas with high humidity levels, such as basements, crawl spaces, or areas prone to water leaks. Reducing moisture levels in your home by fixing leaks, improving ventilation, and using dehumidifiers can make your property less appealing to these spiders.

Sealing Entry Points

Identifying potential entry points

To prevent wolf spiders from entering your home, it is crucial to identify and seal potential entry points. Start by inspecting your property for gaps around windows, doors, pipes, utility openings, and vents. Look for cracks or holes in the foundation and gaps around screens and door frames. Pay close attention to areas where utilities like plumbing or electrical wires enter your home, as these are common entry points as well.

Sealing cracks and gaps

Once you have identified potential entry points, seal any cracks and gaps to prevent spiders from getting inside. Use a silicone-based caulk or weather-stripping to seal gaps around windows and doors. Fill cracks in the foundation with an appropriate sealant. Pay particular attention to smaller cracks and crevices, as wolf spiders can squeeze through remarkably small openings.

Repairing damaged screens

Inspect window and door screens for any tears or holes. Repair or replace damaged screens to ensure they remain an effective barrier against spiders and other pests. Even the smallest hole can be an open invitation for a determined wolf spider.

Installing door sweeps

One commonly overlooked entry point for spiders is the gap between the bottom of exterior doors and the floor. Install door sweeps to eliminate this space and create a tight seal. This simple addition can go a long way in preventing spiders from gaining access to your home.

Securing vents and utility openings

Check vents and utility openings around your property for any openings that could provide an entry point for spiders. Use appropriate covers or screens to secure these openings while maintaining proper ventilation and function.

Reducing Outdoor Attractants

Trimming vegetation and bushes near the house

One effective way to reduce the chances of wolf spiders entering your home is to trim vegetation and bushes near the house. Spiders often use overgrown plants and shrubs as launching points to access your home. Regularly trimming them and maintaining a tidy yard can discourage spiders from approaching your property.

Proper outdoor lighting

To minimize the attraction of wolf spiders, it is important to use proper outdoor lighting. Opt for lighting fixtures with reduced brightness that do not create unnecessary glare. Position lights away from entry points or use motion sensor lights that activate only when needed.

Removing woodpiles and debris

Woodpiles and debris provide shelter for insects, which in turn attract spiders like wolf spiders. Remove any unnecessary woodpiles, leaf piles, or other debris from around your property. Keeping your yard clean and free of clutter will make it less inviting for spiders to take up residence.

Clearing clutter and excess objects

In addition to maintaining a clean outdoor environment, it is equally important to keep the interior of your home clutter-free. Eliminate unnecessary objects and clutter that can provide hiding spots for spiders. Regularly declutter and organize storage areas, basements, and attics to minimize potential habitats for these spiders.

Effective Spider Repellents

Natural repellents

There are several natural repellents that can help deter wolf spiders from entering your home. Peppermint oil, vinegar, and citrus peels are known to repel spiders. Simply dilute them in water and spray the mixture around entry points or areas where spider activity is prevalent. Additionally, placing cedar chips or horse chestnuts in specific areas can also discourage spiders.

Chemical repellents

If natural repellents are not sufficient, there are chemical repellents available on the market specifically designed to repel spiders. These repellents typically contain synthetic pyrethroids, which are effective in repelling spider species like wolf spiders. Follow the instructions on the product label to ensure safe and proper application.

Essential oils

Certain essential oils are known to have a repelling effect on insects and spiders. Oils such as lavender, eucalyptus, and tea tree oil can be diluted in water and used as a spray to create a barrier against wolf spiders. Apply the mixture along windowsills, door frames, and other potential entry points.

Chestnuts and hedge apples

Odd as it may sound, placing chestnuts or hedge apples near entry points or in areas prone to spider activity can act as a deterrent. While the scientific evidence behind their efficacy is limited, some people swear by their success in keeping spiders away.

Regular Cleaning and Maintenance

Vacuuming regularly

Regular vacuuming is essential to eliminate spider webs, eggs, and potential food sources. Pay close attention to corners, ceilings, window sills, and baseboards. Use the vacuum cleaner’s crevice tool to reach into cracks and crevices. Empty the vacuum bag or canister outside to avoid spiders escaping back into your home.

Dusting and removing cobwebs

Dusting regularly with a microfiber cloth helps eliminate spider webs and keeps your home free of potential hiding spots. Pay attention to hard-to-reach areas, such as ceiling corners and light fixtures. Removing existing cobwebs reduces the chances of attracting spiders.

Organizing storage areas

Spiders, including wolf spiders, are attracted to dark and cluttered areas like basements, garages, and attics. Keep these areas organized, frequently declutter, and store items in sealed containers whenever possible. This makes it less likely for spiders to find suitable habitats within your home.

Maintaining cleanliness in dark and damp areas

Dark and damp areas, such as basements and crawl spaces, are particularly attractive to wolf spiders. Regularly clean and inspect these areas to minimize moisture, remove any potential food sources, and discourage spider infestations. Use dehumidifiers if necessary to control humidity levels.

Using Traps and Insecticides

Placing sticky traps

Sticky traps can be an effective means of capturing and controlling spiders, including wolf spiders. Place these traps near areas of high spider activity, such as entry points, windowsills, or corners. The adhesive surface of the trap will catch spiders as they walk over it. Regularly check and replace the traps as needed.

Applying residual insecticides

Residual insecticides can be used as a barrier treatment to prevent spiders from entering your home. Apply these insecticides along baseboards, window frames, and other potential entry points. Be sure to use a product specifically labeled for spider control and follow all safety instructions. If you have concerns about using insecticides indoors, consult with a professional pest control company.

Using natural insecticide sprays

If you prefer natural alternatives, there are commercially available insecticide sprays made from plant-based ingredients. These sprays are designed to repel spiders and can be applied to areas where spider activity is prevalent. As with any product, carefully follow the instructions provided by the manufacturer.

Utilizing Spider-Repelling Plants


The pleasant scent of lavender not only has a calming effect on humans but also repels spiders. Plant lavender in pots or in your garden near windows, doorways, or other potential entry points. The scent emitted by the plant acts as a natural deterrent.


Mint is another plant that spiders tend to avoid. Its strong aroma disrupts their sensory receptors, making them less likely to approach your home. Plant mint in pots or in your garden to help keep spiders at bay.


Known for its pungent scent, eucalyptus is an effective spider repellent. Plant eucalyptus trees or shrubs in your yard or place eucalyptus branches near entry points or areas of spider activity. The fragrance emitted by the plant acts as a natural deterrent.


Citronella is well-known for its mosquito-repelling properties, but it can also repel spiders. Plant citronella grass or place citronella candles near outdoor areas to minimize spider populations and reduce the chance of them entering your home.


Marigolds not only add vibrant color to your garden but also deter spiders. The strong scent of marigolds is known to repel several insect and spider species. Plant marigolds in your garden or place potted marigolds near windows and doors to create a natural barrier against spiders.

Employing Professional Pest Control

Assessment and consultation

If your efforts to control wolf spiders have been unsuccessful or if you have a severe infestation, it may be beneficial to contact a professional pest control company. An experienced technician can assess your property, identify potential hotspots, and offer tailored recommendations to address your spider problem.

Treatment options

Professional pest control companies have access to a range of treatment options that are typically more potent and effective than over-the-counter products. They can apply residual insecticides, perform targeted treatments, or utilize specialized techniques to eliminate existing spider populations and prevent future infestations.

Regular maintenance and follow-ups

By engaging a professional pest control service, you can benefit from regular maintenance and follow-up treatments. Follow-up visits ensure that any remaining spiders are dealt with and that preventive measures are in place. Regular maintenance can help provide long-term relief from wolf spiders and other pests.

Preventing Spider Encounters Indoors

Checking and shaking out clothing and shoes

Before putting on clothing or shoes, give them a quick check and shake to dislodge any spiders or other insects that may have taken refuge. This simple habit can help prevent unexpected encounters with wolf spiders.

Inspecting outdoor gear and equipment

Similarly, inspect any outdoor gear or equipment that could have picked up spiders during use. Shake out camping gear, gardening tools, or sports equipment before bringing them inside your home.

Keeping a tidy and clutter-free environment

Maintaining a tidy and clutter-free environment not only helps reduce potential hiding spots for spiders but also makes it easier to spot their presence. Regularly clean and declutter your living spaces to minimize the chances of encountering wolf spiders indoors.

Maintaining proper sanitation

Good sanitation practices are essential in keeping wolf spiders and other pests at bay. Clean up spills promptly, store food in airtight containers, and regularly dispose of trash. By denying spiders access to food sources, you make your home less appealing to them.

By implementing these measures, you can significantly reduce the chances of encountering wolf spiders in your home. However, it is important to remember that occasional spider sightings are not unusual, as they are a common presence in our environment.
