At What Temperature Do Roaches Die? Roaches’ Preferred Temp


Roaches, known for their resilience and adaptability, can thrive in almost any environment, including extreme temperatures. However, their tolerance has limits. In this blog, we will answer the question of at what temperature do roaches die and how temperature can be used in the battle against these pests.

Understanding the limits of roach tolerance can help you win the war against roach infestations. Whether you’re dealing with a small infestation or a full-blown roach invasion, understanding the limits of roach tolerance can help you develop an effective pest control strategy.

At What Temperature Do Roaches Die

What Temperature Kills Cockroaches? At What Temperature Do Roaches Die?

Cockroaches can tolerate a wide range of temperatures, but they do have a temperature tolerance threshold.

  • Temperatures below freezing or above 122°F (50°C) will kill them.
  • They will die if exposed to temperatures above 140°F (60°C) for more than a few minutes.
  • At temperatures below 50°F (10°C) or over 95°F (35°C), they may become less active.
  • They’re most active at temperatures between 70-80°F (21-27°C).
  • The specific temperature of death varies depending on the species and exposure time.

It is more effective to use temperature to deter or repel cockroaches, rather than trying to kill them outright. Weatherstripping and sealing cracks or crevices around doors and windows can prevent cockroaches from entering your home.

Using a dehumidifier to reduce humidity also helps, as cockroaches thrive in moist environments. By making your home less attractive to cockroaches, you can prevent infestations.

Will Cockroaches Survive the Winter?

Cockroaches can survive cold temperatures, but their ability to do so varies by species. The American cockroach, for example, is more tolerant of cold than others and can survive outdoors in cold climates. However, most cockroach species cannot withstand the extreme cold for long and will look for warm, moist environments.

  • Cockroaches are more likely to survive winter if they can find warm, moist shelter, such as inside a heated building.
  • They may reside in basements, crawl spaces, or under appliances where it is warm and moist.
  • While some cockroaches can survive winter outdoors, it’s more common for them to seek warm protection.

Prevent cockroaches from entering your home: Seal cracks or crevices around doors and windows, reduce humidity with a dehumidifier, and use weatherstripping or other methods to prevent entry through small openings. These steps can reduce the risk of a cockroach infestation and protect your home.

How Long Can Cockroaches Survive In Low Temperatures?

How Long Can Roaches Survive In Low Temperatures

Cockroaches can’t survive extreme cold for long and seek warm, moist environments when temperatures drop. The survival time depends on the species and temperature. American cockroaches are more tolerant of cold but most species can’t survive prolonged exposure.

To prevent cockroaches from entering your home, seal cracks and reduce humidity with a dehumidifier. Use weatherstripping to prevent cockroaches from entering through small openings. Taking these precautions can help reduce the risk of infestations and protect your home.

What Temperatures Do Cockroaches Prefer?

Cockroaches thrive in warm, humid environments with temperatures between 70-80°F (21-27°C). At these temperatures, they can move and forage efficiently. However, they can tolerate a range of temperatures but may become less active at temperatures below 50°F (10°C) or above 95°F (35°C).

To prevent infestations, keep your home cool and dry, especially in areas like kitchens and bathrooms. Using a dehumidifier can also reduce the humidity and make your home less attractive to cockroaches.

  • Can roaches be killed by heat?

    Heat is an effective way to kill roaches. They can’t withstand high temperatures for long periods. Most roaches will die if exposed to temperatures above 140°F (60°C) for more than a few minutes. However, the specific temperature varies depending on species and exposure time.

  • Can roaches survive in a cold house?

    Roaches can tolerate brief periods of cold temperatures but not prolonged exposure to extreme cold. They will seek shelter in warm, protected locations when the temperature drops.


Roaches can survive in a wide range of temperatures, but there is a limit to their tolerance. Generally, roaches can’t survive temperatures below freezing or above 122°F (50°C). However, the temperature at which roaches die varies depending on the species and the length of exposure to extreme temperatures.

While extreme temperatures can deter roaches, making your home less attractive to these pests is a more effective method. This can be achieved by sealing cracks and crevices, reducing humidity, and keeping the home cool and dry.

By understanding roach tolerance and protecting your home, you can effectively control these pests and prevent infestations.
