Where the bugs play, the wolf spiders will stay for their prey. Like most animals and insects, spiders live in a survival instinct to go where the food is. Sadly, these places can be your house, your room, or your closet.
If you’re in search of the best pesticides for wolf spiders, we select the efficient solutions to keep those small crawlers away for good.
Wolf spiders are soft-bodied insects that do not cause infestation like insects but can be dangerous to have at home. They are bigger than insects which can cause a painful bite. If you catch them in the wrong method, you’ll only spread more spiderlings in your house than eliminating them.

What Are Wolf Spiders?
Wolf spiders look like one of the scary creatures you’ll find in a horror-fiction movie. Despite their appearance, they are shy, introverted, and harmless types of arachnids. They play an important role in the ecosystem and are an ally to homeowners when it comes to bug control.
They feed on the following pests:
Wolf spiders are also called hunting spiders because of their efficient hunting abilities. They have sharp eyes that can see even the slightest movement from the bugs. When the situation calls for it, they can pounce their prey until it dies.
The distinct features of wolf spiders are their three rows of eyes. The light from a light source reflects on their eyes in the dark, making them easy to detect at night time. They have shorter legs than other spiders and do not spin webs to catch their prey.
Due to their role in the environment, it is best to leave one or two wolf spiders alone. However, if their numbers are growing on your property, they can be a nuisance rather than a dangerous threat. You can eliminate them using different pest control methods.
Let’s admit it, it would be kind of freaky to have so many eyes looking at you while you sleep or when you’re doing some chores. Their bite can also be stingy and its venom might cause allergy to some people. Their venom is non-lethal and may only cause temporary symptoms, such as:
- Mild pain
The impact of a wolf spider bite eventually subsides and can only last for minutes to a few days. However, if the rash or swelling moves away from the treated area and the patient has fever or nausea, it’s best to call a medical professional.

How To Get Rid of Wolf Spiders For Good?
Most of us are afraid of spiders simply because of their multiple legs and an unusual number of eyes. They stare at you like you’ll be crushed with a wrong move.
However, they only visit your humble home because their stash of food is also around the nooks and crannies of your house.
Pest control will be smooth sailing if you know what you’re targeting. Are you sure you’re dealing with wolf spiders?
The first step for pest control is proper identification.
1. Identify The Type of Spiders in Your Property
Most pest control service providers use three parameters in identifying the kind of spiders they have at home.
Unless you’re willing to stare at them and observe, here are some of the essential features to look for:
- No. of eyes: If you get a glimpse of their teeny weeny eyes, wolf spiders have three rows of eyes where two large-sized ones are at the top row, two medium-sized eyes in the middle, and four small eyes at the bottom. They have the third-best eyesight among other spiders.
- Size: A wolf spider measures around 1 inch to 2 inches. It has short legs and a stout body and has markings on its body for camouflage reasons.
- Color: Wolf spiders don’t have flashy colors and mimic the colors of their habitat. If you found their nest in your yard, they will likely have brown markings.
- Behavior: They have unique behaviors that set them apart from other types of spiders. These behaviors are:
- Unlike a typical spider, they do not spin webs and attack their prey by running too fast. They hold their prey on their legs before eating them.
- They are not aggressive and won’t jump at you at any given minute. They only bite when provoked like sweat bees.
- As a solitary type, they burrow their nest in the soil or any gaps and crevices in your house.
- As parents, wolf spiders carry their egg sacs at the end of their abdomen. Once the eggs are hatched, they still carry the spiderlings on their back until they’re old enough to protect themselves.
2. Find Their Hideout
Once you confirm that you are dealing with wolf spiders, it’s time to find their hideout. You won’t find them busy spinning their webs.
Instead, you’ll find them in places with high bug traffic. Their favorite hideouts include:
- Gaps and holes in the wall
- Cluttered areas
- Under leaves and plants
- Under rocks
- Inside or under logs
3. Controlling The Wolf Spider Population
Before you use any pesticide to clear these elusive but intimidating arachnids, you must first try to get rid of their food source.
Here are the step-by-step control measures that you can do to keep wolf spiders out of your house:
(1) Declutter your house: Bugs love to crawl and nest on skimpy spaces between cluttered boxes and materials. They can hide in any location that subsequently invites their predators-wolf spiders.
Try decluttering your home by sending excess equipment for donation or selling them online. Also, bugs and spiders love cardboard boxes, so make sure to get rid of them as soon as possible.
(2) Apply any best pesticides for wolf spiders: Select one of the pesticides from our list above and spray it in areas where they will likely stay. Spray fervently around the house when the weather is about to change.
Wolf spiders love to stay indoors when the weather’s getting colder or when it’s rainy. In some cases, they also spread like wildfire during summer.
- Place spider traps where you usually see bugs or spiders around. One of the homeowner favorites is TERRO Spider & Insect Traps.
- Clear out webs whenever you see them. Though wolf spiders do not spin webs, other spiders may still be around your house. You may use a cobweb duster to clean out-of-reach ceilings like the Extend-A-Reach Cobweb Duster Head Brush.
You can also wipe down the walls with a solution to permanently rid them off with cobwebs. These include:
4. Prevent Future Wolf Spider Infestation
Once your house is squeaky clean from bugs and spiders, your next goal is maintenance. Otherwise, you’ll be dealing with another set of wolf spiders around your house. The best prevention tips include:
- Seal any crevices and holes around the house. It will not only keep spiders away but also other possible pests around like skunks or bees.
- Apply preventive pest control once in a while. Make it a part of your annual home maintenance.
- Get rid of bugs around your house. Always remember that when there is a food source, predators like wolf spiders will keep coming.
Pro Tip: Dos and Don’ts in controlling wolf spiders: Unlike other insects, avoid taunting a wolf spider to prevent it from being aggressive. You should also avoid swatting or squishing them to avoid spreading hundreds of their spiderlings.
The best pesticides for wolf spiders are solutions containing pyrethrin and its type like bifenthrin, cypermethrin, etc. Wolf spiders also hate the smell of peppermint essential oils.
