Why Is My Home Full of Spiders During the Cold Months?

Indoor spider common in the winter months, perfect for Schendel Pest Control services.

When fall turns into winter, spider sightings often increase inside Kansas, Missouri, Arizona, & Arkansas homes. Cooler temperatures push both insects and spiders to seek shelter indoors. The main reason is a change in food availability as outdoor conditions worsen. As insects outside die off or become inactive, indoor insects become far more appealing to spiders.

Spiders are especially attracted to pests like cluster flies, fungus gnats, and beetles. These insects move indoors to escape the cold and quickly become a food source. Once insects settle in, spiders are never far behind.

Seasonal breeding patterns also play a role for Kansas, Missouri, Arizona, & Arkansas homeowners. Many spider species mate during the fall and winter months. This behavior results in increased spider activity throughout homes in Kansas, Missouri, Arizona, & Arkansas.

Where Else Can Spiders Be Found in Winter?

Indoor winter spiders are usually not new arrivals from outdoors. Most house spiders have lived inside your home long before temperatures dropped. Cold weather simply changes their behavior and movement. As they become more active, they are easier to spot while hunting prey or seeking mates.

Many ground-dwelling spiders spend winter buried in soil or hidden within tree bark. Web-building spiders commonly shelter in areas like hollow logs, under siding, or inside stacked firewood. Other spiders rely on silk-lined retreats that insulate them from cold temperatures.

Do Spiders Seek Shelter Indoors in Winter?

Yes, but not all spiders need to come inside to survive winter, as many can handle freezing temperatures outdoors.

Many species have natural defenses against the cold. Some create antifreeze-like substances in their bodies to prevent freezing damage. These adaptations allow them to remain dormant until warmer weather returns. Others survive by hiding under bark, in leaf piles, or underground, where the cold is less severe.

How Long Do Spiders Stay Hidden During Winter?

In regions with mild winters, spiders may only remain inactive for a short period. In colder climates, they can stay inactive for several months, often from late October through early April. While this is often called hibernation, spiders do not truly hibernate. Instead, they enter a state known as diapause, where their metabolism slows, they stop eating, and movement becomes minimal.

Shorter days and falling temperatures signal spiders to prepare for winter. This pushes them to seek protected spaces where conditions are more stable. These locations can include homes, but also loose tree bark, rock crevices, and other sheltered outdoor areas.

How Do Spiders Survive the Winter Months?

Spiders inside your home survive by feeding on the insects they find. This can include fruit flies near the kitchen, pantry moths, and other small pests that thrive in indoor environments. As long as these food sources are present, spiders remain active throughout winter.

Spiders that stay outdoors eat far less during the cold months. They may catch an occasional insect on warmer days, but mostly survive using fat reserves stored from summer and fall. To manage spiders during winter, follow this multi-step process:

  • Control Moisture: Lower indoor humidity by using dehumidifiers and repairing any leaks. A dry home is less appealing to both spiders and the insects they feed on.
  • Limit Outdoor Lighting: Reduce outdoor lighting near windows and doors. Lights attract flying insects, which can then draw spiders inside.
  • Regular Cleaning: Stick to a regular cleaning routine. Vacuum at least once a week, focusing on baseboards, window frames, and ceiling corners.
  • Use Natural Repellents: Apply natural deterrents in problem areas. Spiders tend to avoid strong scents like peppermint, eucalyptus, and citrus.
  • Hire Professionals: Bring in professional exterminators. They can assess your situation and provide solutions tailored to your home.
