As winter approaches and temperatures drop, many creatures prepare for hibernation. But what about our eight-legged arachnid friends? Do spiders also hibernate during the colder months?

If you’re worried about spider activity in your home this winter or are an outdoor enthusiast wondering if their presence will dwindle, you’re in good company. In this article, we will explore whether spiders hibernate, along with other seasonal behaviors.

Adaptations for Winter Survival

Like other insects and arachnids, spiders are ectothermic creatures. This means their body temperature is determined by their environment. As the temperature falls, their metabolic rate slows, causing them to become less active.

However, unlike some animals that enter a true state of hibernation, spiders have unique ways of dealing with the harsh winter conditions. Over time, they’ve developed various survival strategies to use during the colder months. Let’s explore some of these fascinating adaptations:

Seeking Shelter

Spiders seek shelter in protected areas like small crevices, cracks, and even inside homes when temperatures fall. These hiding places provide insulation and protection from harsh weather. So, encountering a spider in your house during winter is not uncommon!

Lowered Activity Levels

Spiders become less active during winter because the amount of available prey insects decreases dramatically. Some conserve energy by staying in their shelters until warmer weather returns, and some reduce movements like web-building activities.

Instead of constantly building new webs, these spiders often repair and maintain their existing webs during winter. By minimizing unnecessary energy expenditure, they can focus on survival until better hunting conditions return.

Antifreeze Production

Certain species of spiders have developed an impressive survival mechanism that involves producing an antifreeze-like substance. This substance prevents ice crystals from forming within their bodies, allowing them to withstand freezing temperatures without damage.

Other Spider Activity During Winter

Contrary to popular belief, spiders don’t entirely disappear during winter. They might remain active throughout the season, albeit in less noticeable ways. Here’s what you need to know:

Indoor Spider Sightings

It’s not uncommon for homeowners to spot spiders indoors during winter. The warm conditions and abundance of prey inside homes make them attractive shelters for spiders seeking refuge from the cold. So, don’t be surprised if you come across a few eight-legged guests!

Outdoor Web Presence

Despite reduced activity in winter, some resilient spider species continue spinning webs outdoors even when temperatures fall. These hardy creatures catch unsuspecting insects, like hibernating flies or other small arthropods, in their intricate traps. So keep an eye out for snow-dusted spider webs!

Bottom Line: Do Spiders Hibernate or Not?

While spiders may decrease their activity levels, seek shelter, and adopt survival strategies, they don’t enter a true state of hibernation. Unlike mammals, spiders don’t experience prolonged periods of dormancy but do adjust their behavior according to seasonal variations.

Maintenance to Prevent Spiders Seeking Shelter in Your Home

Because spiders won’t be hibernating, there are steps you can take to discourage them from seeking shelter in your home during winter (or any time, really):

  • Caulk cracks and crevices around your home’s exterior to seal off potential entry points. This action can deter spiders by removing access to warm indoor temperatures.
  • Trim back vegetation touching your home’s exterior walls. This eliminates protective hiding spots near your residence.
  • Vacuum and dust regularly to remove spiders and their webs. This eliminates their food source.

When to Call a Professional

Most spiders you encounter in winter are harmless and merely seeking shelter, but in some cases, you might need professional help. Contact a licensed exterminator if you have an extreme spider infestation with excessive webs and spiders in your home. Also, call for help if you spot potentially dangerous spiders like black widows or brown recluses.

If spiders inhabit your house year-round rather than just occasionally in winter, professional pest control is recommended. Lastly, if you have health concerns about spiders, such as allergies, an exterminator can help identify and safely remove hazardous spiders. They have the necessary tools, products, and expertise to eliminate infestations effectively.


While spiders tend to reduce their activity in frigid winter temperatures, they have adapted unique behaviors to survive seasonal changes without hibernating.

As temperatures drop, expect to see spiders in search of warmth, but know they do not vanish. Understanding their winter adaptations allows us to marvel at their resilience and coexist safely during the colder months.
