Where Do Cockroaches Go in the Winter?

“Where do cockroaches go in winter? Do they migrate to warmer areas?”

Cockroaches do not go anywhere in winter except indoors. Common pests like American, German, and Oriental Cockroaches prefer warm weather and can struggle to survive in winter temperatures. Rather than migrating or hibernating, roaches will instead seek new sources of shelter.

In winter, roaches can be attracted by the warmth from:

• Central heating
• Heating ducts
• Boiler rooms
• Motors for appliances like fridges and washing machines
• Light fixtures
• Drains and sewers

Cockroaches can hitch a ride indoors during winter by hiding in piles of firewood or old furniture. Pipes that warp or crack from frost damage can also offer entry points, as can poorly sealed windows and other fixtures.

So, while winter makes outdoor conditions difficult for cockroaches, it also makes dwellings and businesses more inviting. Infestations can become more concentrated and visible, with a combination of heat, shelter, and access to food that can sustain continued breeding.

If you find evidence of cockroaches during winter, be sure to contact a pest control technician. They will be able to find where the pests are getting in and then help you remove them.
