Understanding Cockroach Behavior in Winter
When the temperature drops, cockroaches ditch the outdoors for cozy indoor hideouts. It's this time of year when most of us stop seeing bugs crawling around due to insects' version of a hibernation-like state: a phase called diapause.
Diapause suspends cockroaches' normal activity, which means their reproduction and metabolic rate slow down. Many cockroaches take this time to find shelter so they can stay warm and stay fed if they need it. This is the time of year when cockroaches enter homes and use your wall voids and other areas as a hideout from the cold weather and any predators. Though roaches slow down a little, they do remain active during the winter months.
Winter doesn't slow these pests down; it centralizes them, making it the perfect time to tackle an infestation. Here's how they operate when it gets cold:
Home Sweet Home: Cockroaches, like unwanted holiday guests, seek warm refuges to survive the winter. Your heated home offers the perfect sanctuary.
The Usual Suspects: German cockroaches are especially notorious for thriving indoors during winter, hiding and reproducing in interior walls, rafters, and even sheetrock.
Basement-Dwellers: Oriental cockroaches are tough cookies that can survive lower temperatures, often making themselves comfortable in basements, crawlspaces, and floor drains.
Cold-Fleeing Cockroaches: American cockroaches can't handle temperatures below 15°F, so they actively seek shelter inside to avoid the winter chill.
Can Cockroaches Survive Freezing Temperatures?
Cockroaches have a tough exterior, but even they have their limits when it comes to the cold:
No Match for the Deep Freeze: Cockroaches can't survive long-term exposure to temperatures below 15°F. This forces them indoors, where they can continue their routines in warmth.
Hibernate to Survive: Some cockroaches enter a state of diapause when temperatures drop below 40°F, conserving energy until conditions improve.
Survival Basics: German cockroaches, as long as they have food and shelter, can easily ride out the winter months inside your home.
It's safe to say that though the weather has gotten colder, you aren't spared from a cockroach infestation. Depending on where you live, you may run into a brown-banded cockroach taking advantage of your crawl spaces or even German cockroaches around your garbage cans hunting for food scraps.
These persistent pests can survive year-round because they have the ability to tolerate lower temperatures than many other pests.
Winter Cockroach Prevention and Control
Common Infestation Areas
When cockroaches seek refuge from the cold, they gravitate toward dark, damp, and undisturbed areas. Here's where these sneaky pests might be hiding:
Basements and Crawlspaces: These cool, damp environments are a haven for many cockroach species. Basements with poor ventilation or cluttered crawlspaces can provide the perfect hiding spots for roaches looking to escape the chill.
Floor Drains and Sewers: Oriental cockroaches, also known as "water bugs," thrive in damp locations like floor drains, sewer lines, and sump pump areas. These spots provide moisture and easy access to food sources.
Decaying Trees and Wood Piles: Outdoor areas like rotting logs or stacked firewood can be attractive to American cockroaches. These pests may start outside but will quickly move indoors when temperatures drop, seeking warmer shelter.
Regular inspections of these areas, combined with proper cleaning and pest-proofing, can help you stay ahead of winter cockroach infestations.
Prevention Tips
The best offense against winter cockroaches is a strong defense. Here's how to make your home less inviting during the colder months:
Seal the Cracks: Use caulk to block all potential entry points around windows, doors, and baseboards. Install door sweeps to help avoid a draft as well as sneaky intruders!
Sanitation is Key: Keep your home spotless—cockroaches are opportunistic feeders, so crumbs and spills are their dream buffet.
Secure Your Snacks: Store food in airtight containers and avoid leaving pet food out for extended periods.
Keep the Sink Clear: Don't let dirty dishes pile up, and be sure to clean up crumbs and spills. You will definitely not want to leave anything in your kitchen sink overnight!
Perform Your Own Inspection: Things as minuscule as leaking pipes can look like a giant vacancy sign to roaches looking for resources to get them through the winter. They will search for warm and damp areas like bathrooms to help them survive.

Effective Control Methods
It's not uncommon for people to see cockroaches in their homes and decide they want to evict them A-S-A-P! Unfortunately, this can lead to bigger issues if not done properly.
At Greenix, we see cockroach control gone wrong all too often. Most people think they can bomb their house with a store-bought product, and it will fix all their problems. In reality, this only buys you a little time before a bigger infestation occurs.
Store-bought solutions are not powerful enough, and without knowing exactly where the roaches are hiding, it's nearly impossible to treat them yourself. That's why professional pest control is so crucial to protecting your home.
The best time to get professional pest control done is in the winter when these pests are centralized and unsuspecting. Because they all move indoors, our pest experts are able to target them more easily, ensuring that come spring, you don't have to worry about hundreds of these pests emerging after laying somewhat dormant during the cold months.
Though cockroaches thrive in warm environments, taking them out in the winter is the most effective strategy for keeping your home as pest-free as possible during other points in the year. Work with the pest nerds at Greenix to stay ahead of infestations no matter what season! Schedule your next pest control service today.
