Cockroaches are one of the most resilient pests, but what happens to them when temperatures drop? Many people assume that cold weather eliminates cockroaches, but that’s not entirely true. Let’s explore where cockroaches go in winter and how they survive the cold months.
Some species, like the American cockroach, slow down their activity in colder months, but they don’t completely disappear. Others, like the German cockroach, are more dependent on human environments and remain active year-round.
Do Cockroaches Die in Winter?
Cockroaches are cold-blooded insects, meaning they rely on external temperatures to regulate their body heat. While they struggle in extreme cold, most species don’t simply die off in winter. Instead, they seek warmth, food, and shelter to survive.

Where Do Cockroaches Go in Winter?
During winter, cockroaches look for warm, humid places where they can thrive. Here are some of the most common places they hide:Inside Homes and Buildings
Roaches seek warmth in kitchens, bathrooms, basements, and attics.Behind Appliances
Warm areas near refrigerators, ovens, and water heaters are ideal hiding spots.Inside Walls and Pipes
They use gaps in walls, drains, and plumbing to travel and stay warm.Sewers and Drains
Some cockroach species remain active in underground sewer systems.How to Prevent Cockroach Infestations in Winter
Since roaches move indoors during colder months, it’s important to take steps to keep them out:Prevention Tips
-
Seal Cracks and Gaps: Check for openings around doors, windows, and pipes, and seal them with caulk. -
Eliminate Food Sources: Store food in airtight containers, wipe down counters, and clean up crumbs.
-
Reduce Moisture: Fix leaks, dry out damp areas, and use dehumidifiers in basements and crawl spaces.
-
Keep Your Home Clean: Declutter and vacuum regularly to remove potential hiding spots.
Do cockroaches die in winter?
No, cockroaches do not hibernate in the traditional sense. Instead of entering a deep, inactive state like some animals do, they slow down their activity and seek warm, sheltered environments to survive cold temperatures.How Do Cockroaches Survive Winter?
- Indoor Species Stay Active – German cockroaches, for example, thrive in heated homes and buildings, staying active all winter.
- Outdoor Species Become Less Active – Some species, like the American cockroach, may slow down their metabolism in colder temperatures but do not fully hibernate.
- Nymphs Can Go Dormant – In extreme cold, cockroach eggs and young roaches (nymphs) may enter a period of slowed growth until warmer conditions return.
