How to Identify and Control Wolf Spiders

Wolf Spider
Discovering that spiders have made their way into your home can be quite disconcerting. You can’t just ignore the problem, as these tiny creatures are able to reproduce and lay 100 eggs every couple of weeks. One spider common to the state of Michigan is the wolf spider. This article will teach you how to identify this specific spider species and keep it out of your home. 


The first thing you need to know about wolf spiders is that they do not build webs. Instead, they hunt their prey during the evening hours. Although these spiders are most active at night, you can still spot one during the day. 
In addition to using vibrations to locate prey, wolf spiders rely on their eyesight. If you get a chance to examine the spider up close, you'll notice their distinctive eye pattern. They have an upper row of two large eyes and two small eyes, and a lower row of four small eyes.  
Perhaps the best way to identify a wolf spider is by its larger size (up to 2 inches in length) and its hairy body. If you come across a mother wolf spider, you'll find her egg sac, filled with as many as 100 baby wolf spiders, attached to the top of her abdomen. Even after the babies are born, they will still attach themselves to the mother wolf spider's abdomen.
Should you determine that you are indeed dealing with a wolf spider, proceed with caution.  

Wolf Spider Bites

Although wolf spiders are typically shy and will run away when they spot a human or an animal, they can bite when they feel scared or cornered. Wolf spiders do release venom when they bite, and this venom is poisonous. While the venom isn't lethal, the bite does require medical attention, especially in small children, the elderly, and anyone with serious health issues. 
The Mayo Clinic recommends cleaning the spider bite with mild soap and water as soon as possible and using a cold compress to help with any pain or swelling. Afterward, you'll need to keep an eye on the bite to make sure it doesn’t become infected — if it does, make sure to get it treated right away. An infected bite would require a round of antibiotics. 


A professional pest control expert knows how to safely remove wolf spiders from your home, as these critters often hide behind houseplants and furniture, down in a dark basement, or inside a closet.
There are different methods of eradication, such as releasing an aerosol bomb, sprinkling a powder like boric acid, or spraying a chemical specifically listed as effective against spiders. Each of these methods requires uncovering all of the wolf spider's hiding places before application can begin, which is why it is so important to seek the assistance of a pest control expert.


Once an exterminator has treated your home and removed all wolf spiders, you'll need to take a few steps to exclude any spiders from coming in and causing a new infestation. Start off by sealing window and door frames, and then move on to adding weather stripping. Take extra care not to leave any doors or window screens open, as the wolf spiders may simply walk in when you aren't looking.
