Nobody likes spiders in their house, and while these pesky critters can be among the more helpful, the wrong varieties can have highly toxic bites. Are spiders active in winter? Learn why you see spiders in your home and what you can do to keep them out.
Are Spiders Active in Winter?
There’s a common myth that spiders enter homes in the fall to get away from the winter cold. In fact, spiders are no more active in winter than any other time of the year. If you see a spider scurrying about your house in the winter, it’s probably been there all year long. According to the University of Washington, less than 5% of spiders seen in your home have ever set foot outside.
How Do Spiders Stay Warm in Winter?
There are over 40,000 species of spiders in the world. Some spiders hibernate through the winter, but you’re unlikely to encounter these in your house as they hide in sheltered areas. Some, however, remain active all winter, and if it’s a mild season, they’ll be hunting all year long.
Spiders are cold-blooded insects that aren’t affected by the cold; they simply adapt. Those that stay active actually produce glycol, a natural antifreeze in their blood.
Where Do They Like to Hide During Winter?
In the winter, spiders prepare nests in shaded, dark, sheltered, and damp places. These nests provide a level of warmth. Some spiders burrow into the ground, while others build little snow igloos. Spiders already in your home don’t need any special winter place to hide because they’re moving around your house all year long.
If you see them scurrying around more, it may be because they’ve gotten comfortable and feel safe moving around, not because there are more of them. On the other hand, it could be that you have an infestation and that they are breeding fast. The more comfortable they get, the more offspring they produce.
Preventing Spiders From Entering Your House
Most house spiders are pretty harmless. They won’t bite you unless they feel threatened. They are usually more concerned with eating other bugs in your home. In this sense, they can be beneficial. Most outdoor spiders won’t come into your home, and those in your home have evolved to live there. That’s why they’re called house spiders.

However, some species, like the brown recluse and black widow spiders, can live outdoors or indoors, and they can be dangerous to you and your family. You can use natural repellents like white vinegar, citrus, mint, diatomaceous earth, cedar, and horse chestnuts to repel spiders. You can also dust your home regularly and keep things neat and tidy to clear out their webs. This makes your home a non-welcoming place.
