How To Kill Wolf Spiders and Keep Them Out For Good

Wolf spiders are the type of arachnids you don’t want to mess with. They don’t pose threats like the brown recluse and black widow, but killing them in the wrong way will cause the start of another spine-chilling infestation. Learn how to kill wolf spiders the right way using the three strategic methods we will discuss in this post. 

As homeowners, the sight of a spider will trigger our immediate reflexes to squash and stomp them immediately.

However, doing that to wolf spiders, especially to the female ones will add more fuel to the fire. Learn more about the behavior of these palm-sized spiders so you won’t be wasting your time and energy on unproductive pest control measures.

Why You Should Not Squish Wolf Spiders?

Wolf spiders carry their spiderlings on their back. After the eggs hatch from the lower abdomen of the mother wolf spider, the baby spiders will climb on top of their mother for the first few days or weeks. Once the hundreds of spiderlings are ready for the world, they will eventually detach from their mother. 

A video from the National Geographic wolf spider feature shows how killing a mother wolf spider sends hundred of its spiderlings to run across the room below.

How To Kill Wolf Spiders Without Causing Another Infestation

Now that you know something about the parental behavior of wolf spiders, you can now gear up for a more careful approach in pest control. While you can hire professionals to do the job for you, you can save so much money by doing the following methods yourself:

#1 Set Up Wolf Spider Traps

Glue traps are a fool-proof method for sneaky wolf spiders since they catch their prey by running. It is the best step if you want to steer clear from using chemicals inside your home.

The trusted glue trap brand by most homeowners is the Catch Master Pest Trap. A lot of people swear by this wolf spider trap due to the following benefits:

  • Easy-to-use
  • Strong glue that can catch anything from small insects, palm-sized spiders, roaches to snakes. 
  • Easy to dispose 
  • Peanut butter scent
  • Catch anything that runs around their house

Pro tip: Do not spray any insecticide or spider repellent before placing the glue trap. Otherwise, it will lose its purpose since there’s a high chance that the critters have fled from your house before your place the raps.

If you want to save some dollars and love the DIY stuff, you can also make your wolf spider trap using the good old duct tape. Here’s how:



  1. Cut two 12-inch duct tape and place the sticky part away from the cardboard. 
  2. Attach them in place by sticking two pieces of duct tape on both ends. 
  3. Place it next to the suspected wolf spider nests or under some appliances where they can scurry around. 

The only challenge in using glue traps is placing them where there is a high spider or bug traffic. This means you have to observe where they frequent.

#2 Spray Insecticides

Wolf spiders have three pairs of eyes, no wonder why they have one of the sharpest eyesight among the types of spiders. If some saw how you captured some of their friends using your glue traps, they will probably look for another nest. With that, you’ll need to use a pesticide.

Pyrethrins and pyrethroids are two effective pesticides that can kill wolf spiders and other insects. Pyrethrin is a botanical pesticide derived from chrysanthemum flowers. It is toxic to insects but degrades fast when exposed to sunlight. 

Pyrethroid, on the other hand, is a chemical that mimics the structure of pyrethrins. It is more toxic than pyrethrin and lasts longer in the environment, providing a longer residual effect. 

Bifenthrin, deltamethrin, and cypermethrin are all types of pyrethroids that are used by commercial manufacturers as active ingredients for their insecticide brands in the market. Here are some of the best wolf spider killers that you can try:

#3 Spread Insecticide Dust

Wolf spiders are different from other spider varieties because they play their hunting game on the ground. You can use this advantage by placing insecticide dust where you usually see them running around. Try using Delta Dust and spray it in cracks and hard-to-reach areas using a duster. 

In most cases, one out of the three methods mentioned in this post can already deal with a mild wolf spider infestation. However, if they already grew a community of spiderlings in your house, you better use all three measures to ensure that you can stop their growing population.

How To Keep Wolf Spiders Out For Good

Once you reclaim your home from your unwanted crawling tenants, you should not neglect the most crucial part of pest control – wolf spider prevention.

There are two reasons why spiders are attracted to your house. First, they seek warmth and protection during the cold fall and winter seasons. Second, they found some delicious snacks crawling around your house. 

Focus on what you can control before the seasons change by doing the following prevention tips:

#1 Block Their Entry Points

Placing mesh in cracks makes it harder for pests to create another holes

Keep the sneaky spider out by sealing every crack, crevice, or hole in your house. Since wolf spiders are good at burrowing into weather strips or other light covers, you should add a mesh before covering the holes.

You can use old steel wool or a copper mesh to serve as another layer of protection in case they succeed in removing the first layer of caulk.  

If wolf spiders always come into your house when the seasons change, they are probably entering the tiny space under your doors or windows. 

Make sure to weatherstrip your windows and add a door seal under the door to keep them out. Door seals are not only a solution for pest problems but also for keeping the cold air out during the cold season.

#2 Get Rid of Their Food Source

The competition for food outdoors is very high for arachnids like wolf spiders. So, when the opportunity knocks and they see a single bug entering your house, their hunting instinct comes in full alert.

The main diet of wolf spiders include:

  • Roaches/ water bugs
  • Beetles
  • Ants  
  • Worms  
  • Insect eggs
  • Earwigs
  • Pillbugs  
  • Aphids  
  • Millipedes or centipedes
  • Flying insects

If you have an infestation of roaches, beetles, or ants in your home, expect that the next infestation will be that of wolf spiders. To get rid of these critters out of your house, you must deal with the bugs by doing the following steps:

  • Turn off your porch lights that attract flying insects at night
  • Improve the ventilation of your basement because most bugs love a moist and humid environment.
  • Fix leaking gutters, drain pipes, and faucets
  • Cover open sewage pipes and sewers
  • Remove stagnant water in your bathroom and sink

Improve the drainage around the perimeter of your house using a french drain

#3 Clean up, clean up, clean up

We can’t stress enough how sanitation greatly affects the efficiency of pest control for wolf spiders. Cleaning and decluttering your space will discourage bugs and wolf spiders from staying in your home.

Here are some tips for a bug-free garage, basement, or storage area:

(1) Bugs love staying in cardboard boxes. Roaches, in particular, love sticking their egg capsules on boxes, and wolf spiders may use them as shelter. Prefer using plastic containers with covers for a cleaner look. 

(2) Take advantage of your wall space and hang your tools and gym equipment to reduce the clutter on the ground. 

(3) If you have so much stuff, adding a rack and pegboard may increase the space in your house and make it look more organized.

(4) Organize your tools by function and frequency of use. Place the ones you usually use in a location where you can immediately see them. That seasonal stuff should be stored in a cabinet or at the highest level of a rack.

#4 Cover Cracks and Holes on The Walls

The presence of bugs and wolf spiders in your house is a sign for you to keep up with your home repair and maintenance. Cement the holes and cracks on your concrete walls and fix your sidings. Replace rotten wood and get rid of any water damage around your house, and you’ll surely save a lot more from doing it today than later. 

#5 Plant Wolf Spider Deterrents Around Your House

While we love the fresh scent of herbs like peppermint, wolf spiders and most soft-bodied insects hate them. To keep bugs and spiders off for good, plant peppermint around your house to keep them away. Other herbs that you can plant are:

The good thing about planting herbs is you’re not dealing with your pest problem, you’re also adding a refreshing smell around your home.

If you don’t have a green thumb and find it hard to grow some herbs, you can spray a diluted vinegar solution in your home to deter spiders.
