Wolf Spider Activity During Winter

If you own a home, you’ve no doubt encountered wolf spiders before, and as winter approaches, you may feel like you’re noticing an increase in wolf spider sightings. The good news is they’re nothing to worry about – they’re in your house hunting bugs for you like mini pest control agents. But if you don’t like the sight of them, never fear – understanding why these arachnids remain active during the colder months can help you manage their presence more effectively.

In this article, we’ll delve into the unique behaviors and adaptations of wolf spiders that enable them to thrive even in the winter and offer practical advice on how to keep them at bay.

Why Do You See So Many Wolf Spiders in the Winter?

While most spiders remain dormant throughout the winter months, the unique characteristics of the wolf spider allow it to stay active in even the coldest temperatures. 

Reflectors in its eyes, a unique characteristic of this species of arachnid not seen with others. Though there are many different varieties of wolf spiders, all possess eye reflectors.

This spider species is known for its use of a burrow instead of a web-like structure. This adaptation is especially important for survival in the winter. By burrowing below ground level, wolf spiders aren’t as exposed to the elements as a web-dwelling spider would be. By burrowing extra warmth can also be achieved.

Wolf spiders eat small insects that can be found throughout the winter months, making hunting viable during this period. This nocturnal spider will emerge from its burrow during the night to hunt for prey. The wolf spider will often travel long distances during the night in search of food, often stalking their next meal.

Where Do Wolf Spiders Live in the Winter?

Because wolf spiders are a burrowing spider species, they are unlikely to find a home very hospitable. It is possible, however, that they will burrow in the garden of a home and wander inside occasionally in search of food.

Wolf spiders do produce venom that can be injected with the use of their fangs. This particular species of spider will often pounce on their victim and immediately envenom them, inducing paralysis or death. The wolf spider will immediately eat their prey after hunting.

Where Can You Find Wolf Spiders Hiding?

• Basements and Garages: These areas provide dark, cool, and undisturbed environments that wolf spiders prefer.
• Crawl Spaces: The dark and secluded nature of crawl spaces makes them ideal hiding spots.
• Behind Furniture: Large pieces of furniture that are rarely moved, such as sofas and cabinets, offer good hiding places.
• Underneath Appliances: Spaces under appliances like refrigerators, stoves, and washers are dark and often overlooked.
• Closets: Cluttered or rarely used closets can be inviting for wolf spiders.
• Attics: Attics offer a quiet, undisturbed environment that spiders can find attractive.
• Storage Boxes: Cardboard boxes and other storage containers provide enclosed spaces where spiders can hide.
• Window and Door Frames: Small gaps and crevices around windows and doors are common entry points and hiding spots.
• Bathrooms: Wolf spiders may be attracted to bathrooms due to the presence of water and humidity.
• Under Sinks and Cabinets: Areas under sinks, especially in kitchens and bathrooms, offer dark and secluded spots.
