House spiders prefer to live both outdoors and indoors. But why do we see more house spiders in winter than in summer? There are a variety of reasons for this question. They do this because they’re looking for a warm place to survive, and they can be very successful in their search.

Houses provide plenty of places for them to hide, and many homeowners never even realize that they’ve got spiders living in their homes until the weather starts to get cold. One reason is that some species hibernate during the winter while others remain active.

Additionally, many spiders migrate indoors to escape the cold weather. This can lead to an increase in the number of spiders seen inside houses and other buildings.

Why do we see more house spiders in winter? 

Spiders are able to sense when the weather is changing and prepare for the winter. Interestingly, spiders prepare for winter in different ways.

Why do we see more house spiders in winter?

In the late summer, adult spiders will mate and lay eggs. The eggs will hatch in the spring, and the baby spiders will survive the cold winter temperatures.

Female spiders typically lay their eggs before winter sets in so that the eggs are not prone to freezing. They will also search for a safe and dark place to deposit the egg sac. Other spiders will find a sheltered spot and curl up into a ball until the weather warms up again.

In addition, spiders seek out warm places to live and look for food that will last throughout the winter. Some other species will not hatch their eggs until the spring, while others will hatch baby spiderlings that will live together in the egg sac.

Some spiders will migrate to a warmer climate, while others will stay and hibernate throughout the winter.

Food supply in the winter

Spiders are resistant to the cold because they have a higher metabolic rate than most other creatures. This means that they generate more heat internally and can tolerate colder temperatures.

On the other hand, Insects do not fare as well in the cold, and thus there is a decreasing food supply for spiders in winter.

When the temperature starts to drop and food becomes scarce, some species of spiders go into a dormant stage called diapause. This is where they hibernate and wait for food to become available again.

As a result, we see more spiders in the winter since they are not as active when there is less food around.

The colder months usually bring a reduction in the food supply, which in turn leads spiders to conserve their energy and not go into diapause. Thus, they are more likely to be seen inside people’s homes as they search for food.

Do spiders hibernate in the winter?

There are many different types of spiders, and some will hibernate during the winter months, while others will not.

Spiders that live for more than a year, like the fishing spider and the tarantula, will typically hibernate during the cold winter months. Like the house spider, other spiders will not hibernate but instead stay active all year long.

Both adult spiders and their spiderlings will find a sheltered spot to hunker down. This might be under tree bark, rocks, between the ground and the snow, or even burrowed into the soil like wolf spiders.

A few species take specific measures like spinning a web in their hiding place, while others will wrap themselves in a silk cocoon.

How do spiders survive winter without hibernating?

Spiders are able to survive the winter by going into a dormant state called hibernation. However, many common household spiders do not hibernate.

Instead, they find warm places to hide where they can wait out the cold weather. This is why we see more spiders in our homes in the winter months; they are looking for a place to stay warm.

In colder weather, spiders enter a state of torpor. This is called lethargy, in which the spider consumes less energy and lowers its body temperature to conserve energy. This allows the spider to stay alive during winter without having to hibernate.

Spider antifreeze

Spider antifreeze is a glycoprotein that helps to prevent ice crystals from forming inside their bodies during winter.

The spider’s antifreeze, which is produced in the summer, decreases in production as the weather warms up. The cold weather forces the spiders to produce more of this antifreeze so they can survive.

Spider activity in winter

Spiders that live in colder climates are active during the summer. This is because they need to find food and shelter during this time.

Though spiders are typically thought of as creatures that live in warm weather, common house spiders have learned to adapt to their lifestyle and survive the winter. This is done by living with humans and taking advantage of the warmth that they provide.

Additionally, many house spiders will go into a state of hibernation during the colder months to help them get through them.

Of the spiders you may encounter indoors, five percent of them have never been outside. This is because many spiders migrate in search of food or shelter, and during the wintertime, there are fewer insects for them to eat.

So, if you’re seeing more spiders indoors this winter, don’t worry-they’re just doing what comes naturally to them!

Do all spiders die in the winter?

Two types of spiders are found in homes- those that live for one season and those that will die in the winter.

The spiders that live for one season are the ones you typically see in the summer as they come out to mate. The spiders that will die in the winter are usually the ones that stay hidden all year long.

Though spiders that only live one season will die in the winter, their eggs and young will be taken care of. In fact, many species of spiders overwinter as eggs or juveniles. The adults die off in the cold weather, but their offspring have a higher chance of survival.

How to get rid of a spider in winter?

Removing spiders in winter is not recommended because it can actually do more harm than good. Spiders are beneficial to have around because they help to control the population of other pests.

If you do find a spider in your home, it is best to leave it alone and let it take care of the pest problem.

Spider removal can be a daunting task, as they often hide in hard-to-reach places. In the winter, spiders may be seen more often as they search for a warm place to stay.

Before attempting to remove a spider, it is important to be aware of the risks involved, such as the possibility of being bitten.

Spiders prey on other pests, such as mosquitoes and flies, so they help keep populations of those pests in check. Additionally, spiders play an important role in the food chain.

What You Should Do About Spiders In The Winter

While you may see more spiders in your home during the winter, it doesn’t mean that you have to live with them. House spiders are typically not harmful, but they can be a nuisance.

During winter, spiders tend to enter homes since they are looking for food. Maintain a clean home so the spiders don’t have an easy time finding sustenance.

To discourage these house pests, you should avoid leaving debris piles outside, seal up any cracks, and check for gaps and openings around windows where spiders can enter.

If necessary, seal all openings with caulk or spray foam. If you do see a spider inside, calmly capture it and release it outside.


Spiders prepare for winter in a variety of ways, one being by migrating into warmer climates. Another way they get ready is by building their webs close to the ground so that they can take advantage of the warm air rising from the earth.

And finally, spiders will often increase their production of silk in order to have enough web material to last through the cold weather.

In fact, many people think that there are more spiders in the winter than at any other time of year. However, this largely depends on the species of spider. Some species will die off during the cold winter months, while others will reduce their activity but remain alive.
