Cockroaches are pests that enjoy warm weather and moisture, but have you ever thought about cockroaches in cold climates? So, they cannot stand cooler temperatures. Yet, they find ways to survive and adapt to their surroundings. Some roach types can survive lower temperatures, but some cannot.

Most roaches will try to find different dwellings to stay in the cold weather, such as basements, attics, garages, water collection systems, or any damp areas with the preferred temperature.

Can Roaches Survive In The Cold?

Cockroaches will begin to die when temperatures are below 15 degrees Fahrenheit, and if the temperature is below 0 degrees, they definitely will die. Along with this, when the temperatures get below 40 degrees Fahrenheit, cockroaches lose their ability to breed.

Overall roaches much prefer warm and humid climates and will actively avoid any cold climates.

Will Cockroaches Die In Winter?

No matter if you are dealing with German cockroaches, American roaches, or Oriental ones, they will survive the winter if you leave pet food around your entire house and if they find warmth, heat, and water.

If left outside, these species will die in the cold winter months. However, if cockroaches enter your house and manage to avoid the temperature drops, you will see them in all the small holes in your home. That’s why you might find an uptick in roach activity around your home right when the weather starts to drop because roaches are looking for warmth!

Cockroaches are cold-blooded insects that hate cold winters. These species can live without food and water for a month but cannot regulate their temperature. Therefore, they need a warm temperature.

Should You Expect Cockroach Infestation In Winter?

Although not very often, cockroach infestations can happen even in winter. That is because roaches will find the warm spots in your house to avoid the low temperatures. Warmth is one of the main things that attracts roaches to your home, so you might find an uptick in roach activity when the weather cools off.

Because of the warm conditions in your home, most species will try to find a way into your home in Late Fall and into Winter.

Will You See Dead Roaches If The Temperatures Drop?

Since cockroaches prefer warmer weather, they could freeze if they face harsh temperature falls. If you’re wondering if you’ll constantly find dead roaches around your home in the winter, the answer is, you probably won’t. Generally, if roaches made it into your home during the winter, they’ll either be hibernating or they’ll be warm enough to resume normal activity.

However, most roaches hibernate state (diapause) in winter. In this inactive state, their growth stops, and their metabolic rate slows too. That is why going into your house where they can find food and water is the perfect thing for a cockroach.
