How much heat does it take to kill bed bugs

Resistant pests and bed bugs can be a source of stress and restless nights for both companies and homeowners. Although there are several ways to deal with these unwanted visitors, using heat has shown to be one of the most successful strategies. 

It is crucial to know the temperature at which bed bugs die to eradicate infestations effectively. We’ll get into the details of how much heat is required to kill bed bugs in this post, along with some techniques.

How much heat do you need to heat to kill bed bugs?

Research indicates that bed bugs die after 90 minutes of being in an environment over 113°F (45°C). This temperature is the tipping point where the viability of the pests is seriously endangered. Higher temperatures and longer exposure times increase the efficacy of heat treatment.

A temperature chart to help with the eradication process is provided here:

  • In 90 minutes, bed bugs begin to die at 113°F (45°C).
  • 118°F (47.778°C): 20 minutes of effectiveness.
  • At 100°F (37.778°C), bed bugs start to suffer harm.
  • -13°F: Over several days, kills bed insect eggs and adults alike.

How do you use heat to kill bed bugs?

The heat treatment must be customized to the particular situation to effectively eradicate bed bugs. Depending on the size of the area or the goods you are working with, you may need to use different techniques.

Small objects

Heating smaller objects to 118°F (47.778°C) for 20 minutes works well for those that can tolerate greater heat. This guarantees that bed bugs will be eradicated without causing harm to personal belongings.

Big goods

A more temperate technique may be needed when working with larger furniture or goods that cannot resist extremely high or low temperatures. To make sure that everything is completely eradicated, you might use a temperature of 113°F (45°C) for at least ninety minutes.

Whole Space

It is advised to heat a room or living area to a temperature of 120 to 140 degrees Fahrenheit for a minimum of four hours to address the entire space. Bed bugs and their eggs are targeted throughout the room by this all-encompassing strategy, which ensures that these hardy parasites have nowhere to hide.

The importance of exact temperature control and duration cannot be overstated when it comes to effectively eliminating bed bugs. If the specified temperatures or exposure times are not followed, bed bugs may not be eliminated, giving them a chance to survive and possibly re-infest the space.

What devices can used for heat treatment to kill bugs?

Electric Heaters

The most popular kind of heater used to cure bed bugs for heat is an electric heater. Usually, these are big, strong appliances that can heat a space fast to the desired temperature.

Propane heaters

Another alternative for heat treatment is a propane heater, particularly in larger spaces or situations with limited electric power. Because there is a chance of carbon monoxide poisoning, they should only be used by trained professionals and should be used carefully.

Radiant heaters

Instead of heating the air, radiant heaters directly heat items using infrared radiation. This may be a useful method for concentrating bed bugs in particular locations, like bedding or furniture.


A brand of heaters called ThermaPure was created especially to treat bed bugs with heat. These machines heat a space rapidly and evenly by combining forced air with radiant heat.


Another brand of heaters used to treat bed bugs with heat is called Temp-Air. These devices work similarly to ThermaPure, although they can heat bigger surfaces and are usually more powerful.

What temperature kills bed bugs instantly?

While 113°F (45°C) kills them eventually, 118°F (47.8°C) for 20 minutes ensures instant death.

Can I use a space heater to kill bed bugs?

No, space heaters lack the power and control for even heat distribution, potentially leaving survivors.

How long does it take to heat treat a whole room for bed bugs?

At least 4 hours at 120-140°F (49-60°C) to ensure all hiding spots are reached.

Can I heat-treat my belongings myself to kill bed bugs?

For small items, yes, at 118°F (47.8°C) for 20 minutes. Consider professional help for larger items or valuable possessions.

Is heat treatment safe for my pets and belongings?

Consult a pest control professional for guidance on pet safety and temperature tolerance of your belongings.

How much does heat treatment for bed bugs cost?

Prices vary depending on infestation size and chosen method. Contact local professionals for estimates.


Heat therapy has become a powerful tool in the fight against bed bug infestations. Success depends on knowing the precise temperature at which bed bugs die and adjusting the strategy according to the quantity and type of infected goods or space. 

Together, homeowners and pest control experts may successfully eradicate bed bugs and take back control of their living areas by making sure that the temperature limits are followed and that exact control is maintained.
