Do Pests Die Off in the Winter? Common Winter Pest Myths

Many homeowners assume that cold winter weather naturally keeps pests away. While it’s true that some insects become less active during freezing temperatures, the reality is more complicated. Understanding how pests behave in winter can help you prevent infestations and protect your home year-round.

Here are some common winter pest myths—and the facts behind them.

Myth #1: All Pests Die Off in Winter

The truth:Most pests don’t die off in winter—they simply find ways to survive. Rodents, spiders, cockroaches, and even some insects seek shelter indoors where it’s warm and food is available. That means your home can become an inviting winter haven for unwanted guests.

Myth #2: Insects Are Completely Inactive During Winter

The truth:While many insects slow down or enter a dormant state, others remain active inside your home. Silverfish, ants, and cockroaches often continue foraging for food and reproducing in hidden spaces such as kitchens, basements, and attics.

Myth #3: You Don’t Need Pest Control in Winter

The truth:Winter is actually one of the best times to address pest issues. Rodents and insects are concentrated indoors, making it easier for pest control professionals to locate and eliminate infestations. Preventing pests now can save major problems come spring.

Myth #4: Only Old Homes Have Winter Pest Problems

The truth:Pests are not picky about home age. Newer homes can be just as vulnerable if there are gaps in siding, foundation cracks, or improperly sealed doors and windows. Winter can reveal weak points where pests can enter.

Myth #5: Sealing Up the House Alone Will Keep Pests Out

The truth:While sealing entry points is important, pests can still find ways inside. Professional inspections can identify less obvious vulnerabilities, like vents, crawl spaces, and utility penetrations, which are often overlooked by homeowners.

Protect Your Home from Winter Pests

Even during the coldest months, pests are looking for warmth, water, and food—and your home can meet all three. The best way to prevent infestations is a combination of inspection, prevention, and professional treatment.

A pest control professional can:

• Identify common entry points

• Eliminate active infestations

• Recommend long-term prevention strategies
  

Don’t wait until spring to notice the signs. Taking action in winter ensures your home stays pest-free year-round.
