Temperatures below 32° or above 120° Fahrenheit will kill bed bugs on contact. However, temperature alone is not enough to get rid of the infestation completely.

How hot does it have to be?

It takes at least 30 minutes of exposure to very high temperatures like 120°F to kill bed bugs. Sustain temperatures that are more comfortable for you. Wait until at least an hour to get rid of these parasites. Signs of heat treatments include browning and crispiness on exposed parts of the insect’s body.

Although temperature affects them negatively, they can still hide in other places. This is despite the significant temperature rise. There are many other ways to keep them away.

What Cold Temperature Kills Bed Bugs?

One of these ways is temperature. However, you do not need to place them in a freezer. Very cold temperature itself does not kill bed bugs and their eggs completely. You can still use temperature to control them without letting them get too cold.

Room temperature that is between 65° and 80° Fahrenheit will kill up to 70% of these bugs after two hours of exposure. It may take more time for effectiveness in some areas. Examples are inside hidden crevices or underneath objects that insulate heat.

Can Bed Bugs Live in Cold Temperatures?

The temperature range of 40° to 50° Fahrenheit will kill up to 90% of these parasites within 30 minutes. This temperature range is also considered safe for you. However, temperature alone does not control infestations adequately. Bed bugs are resilient creatures that can survive temperature changes. Eggs can even withstand cold temperatures for several months.

What Temperature of the Steam Is Necessary to Kill Bed Bugs?

A temperature of 120° Fahrenheit is required for bed bugs to die. The steam temperature that is too low will not kill these parasites. For this reason, you must get a steamer that has an adjustable temperature setting. You can start with the lowest temperature and gradually raise it until the infestation is gone.

Which Temperature Kills Bed Bugs Instantly?

The temperature required to kill bed bugs completely is between 122° to 126° Fahrenheit. This temperature range kills 100% of these parasites after 30 minutes of exposure.

The most number of days for this coating to wear off under normal temperature conditions is 10. However, there are other ways for you to ensure your safety from these pests. This is without turning up your home’s temperature too high or too low.

Caution of Using High Temperatures for Killing Bed Bugs

It is important to know that temperature does not kill bed bugs through contact alone. Maintain the temperature for a longer period to take effect. You may also need further help after temperature treatment, like vacuuming or laundering fabric. 

Caution of Using Low Temperatures for Killing Bed Bugs

The extreme temperature that is too low may damage your belongings. The temperature also needs other factors to kill bed bugs through contact.
