Because cockroaches are cold-blooded and unable to maintain their internal body temperature, they prefer warmer temperatures. Roaches prefer a warmer atmosphere ranging from 77 to 104 degrees  Fahrenheit. Coincidentally, this is about the same temperature as the average home (or attic) in the United States. When mercury levels drop during the winter period, roaches tend to disappear. They go in search of warmer turf.

What temperature kills roaches?

Roaches that venture outdoors during the winter cannot survive cold weather with temperatures of 15 degrees Fahrenheit or below. When cockroaches are unable to find a warm environment, they enter a state of diapause--a form of hibernation. In most cases, these drops in mercury levels will cause the roaches to reproduce at a lower rate. As a way of conserving their energy, roaches will slow down altogether. According to research conducted by the University of Massachusetts, cockroaches depend on the winter to develop.

What do roaches do during winter?

Cockroaches are arthropods that are cold-blooded, thereby, unable to coordinate their body temperature. These pests can adapt to practically any condition except for extremely colder temperatures (below 15 Fahrenheit).  When in an environment lower than 45° F or over 115 F, these creatures' metabolic rate slows, and their growth stops.

As the weather gets cooler, cockroaches begin to seek a warmer place. Often, they seek refuge within our warm home. So, how do cockroaches get in the house? They start heading indoors as a way to stay warm because their ability to develop and reproduce is hindered as the weather turns cold. In addition, many cockroaches will not survive for long in low temperatures.

Do cockroaches die off in winter?

Rather than die off, cockroaches go into a hibernation-like state referred to as diapause. While in this state, the cockroaches' rate of growth and metabolism is completely decreased. The cockroach will survive during the winter so long as they have plenty of water and food.

How do cockroaches stay warm in the winter?

When the temperatures start to get cooler, there are several places cockroaches go to seek shelter from the cold, such as:

The ventilation system of a home will attract roaches in their search of food and acquire access to the warmth inside.

• Often the best protection for roaches from rain, wind, and cold weather is decaying trees or stumps.
• Wall cracks and wood piles make excellent sources of warmth for cockroaches when the temperature drops. Cockroaches prefer wood piles that are left undisturbed for any period of time.
• Cracks in the walls and ceiling rafters. These spaces offer pests a place that is warm and insulated, quiet, and away from any danger or predators.
• A chimney top is another place that is warm and safe where cockroaches enter to hide inside.
• Plumbing drains and pipes are excellent sources of moisture that are attractive to oriental cockroaches in house. These pipes and drains also make great places to hide and tolerate lower temperatures.
• Another place cockroaches find safe and warm and a haven for lots of food sources are kitchen counters. They prefer hiding behind a kitchen counter to avert being noticed.
• All homes have electrical appliances with electric motors. These make excellent hiding spots for cockroaches attempting to find warmth. You might discover roaches hiding in coffee machines, microwaves, cookers, and washing machines, just to name a few.
• One of the most popular hangouts for a cold cockroach is in a warm, humid basement. The basement (or attic) of a home is often the best place for cockroaches to hide and hibernate year-round.

Where do roaches go in cold temperatures?

Roaches do not really “go” anywhere during cold weather. Because they are cold-blooded arthropods, they dislike environments that are below 15 Fahrenheit.

The temperature of their body mimics that of the surroundings they live in. Some roaches will go into a form of hibernation known as diapause, allowing their metabolism to reduce and halt growth.

What season do roaches like best?

Weather that is more humid is what roaches like best. This gives them the opportunity to thrive and reproduce quickly. Of all pests, a cockroach is the most resilient.
