Uncovering the Truth: Do Spiders Hibernate in the Winter?

Spiders are one of the most common animals on the planet, and they have been around for millions of years. But do spiders hibernate in the winter? This is a question many people ask, and the answer is surprisingly complex. In this article, we’ll uncover the truth about spider hibernation, including what it is, if spiders do it, and how they survive the winter.

Introduction to spider hibernation

When the weather gets cold, many animals slow down their activity and go into hibernation. Hibernation is a natural process when animals become dormant in order to survive the winter. They reduce their body temperature, slow their metabolism and conserve energy during the cold months. But do spiders hibernate in the winter?

What is hibernation?

Hibernation is a natural process used by many animals to survive the winter. It is when an animal slows its activity and its metabolism in order to conserve energy. During hibernation, animals are in a state of dormancy and their body temperature is lowered. Some animals, such as bears, hibernate for several months. Other animals, such as hummingbirds, may only hibernate for a few weeks.

For animals to hibernate, they must have a suitable place where they can stay warm and safe. This is often underground, where the temperature is more stable. This is why many animals, such as bears and groundhogs, build dens underground.

Do spiders hibernate?

The answer to this question is not straightforward. While some spiders do hibernate in the winter, others do not. It depends on the species and their environment. Generally, spiders that live in cold climates are more likely to hibernate than those that live in warmer climates.

Spiders that hibernate usually do so in sheltered places, such as inside cracks in walls or under stones. They may also build a silken web or burrow underground to protect themselves from the cold.

Common myths about spider hibernation

Although some spiders do hibernate, there are many myths about spider hibernation. One of the most common myths is that spiders hibernate in people’s homes during the winter. This is false. Most spiders that live in homes are indoor species and do not hibernate.

Another myth is that spiders can hibernate for years. This is also false. Spiders typically do not hibernate for more than a few months at a time.

Temperature and spider hibernation

Temperature is one of the most important factors in determining whether a spider will hibernate. Generally, spiders are more likely to hibernate if the temperature is below 50°F (10°C). If the temperature is too high, spiders will not hibernate.

Another factor is humidity. Spiders are more likely to hibernate in areas with low humidity, as this helps them retain body moisture.

Adaptations that help spiders survive the winter

Spiders have several adaptations that help them survive the winter. One of the most important is their ability to reduce their metabolic rate. When spiders hibernate, their metabolic rate slows down and they conserve energy. This helps them survive the cold months.

Spiders also have an exoskeleton, which helps them retain body heat and moisture. Spiders also produce a waxy substance on their bodies that helps protect them from the cold.

Studies on spider hibernation

There have been several studies on spider hibernation. One study found that orb-weaving spiders were more likely to hibernate in colder temperatures. Another study found that some species of spiders were able to survive temperatures as low as -4°F (-20°C).

These studies show that spiders have adapted to survive the cold and they can hibernate in the winter if necessary.

Strategies to reduce spider populations in homes during the winter

Although spiders can hibernate in the winter, it is still possible to reduce their populations in homes during this time. One of the best ways to do this is to keep the house clean and free of clutter, as this will reduce the number of places for spiders to hide.

It is also important to seal any cracks and crevices in the walls or floors, as this will prevent spiders from entering the home. It is also a good idea to use insecticides or sticky traps around the house, as this will help reduce the number of spiders.


In conclusion, spiders can and do hibernate in the winter. It depends on the species of spider and the environment they live in. Spiders have adapted to survive the cold and can reduce their metabolic rate to conserve energy. It is still possible to reduce spider populations in homes during the winter by keeping the house clean and free of clutter and by sealing cracks and crevices.

So the answer to the question “Do spiders hibernate in the winter?” is yes, but only in certain cases. With the right strategies, you can reduce the number of spiders in your home during the winter months.
