In a recent study, the question “Can bed bugs withstand heat?” arose. Researchers conducted sub-acute and acute lethal temperature tests to determine how long it takes for bed bugs to die at specific temperatures. One study found that a 48 degC exposure to adult bed bugs and eggs was lethal. Another study found that an exposure of 45 degC for seven hours could kill the bed bugs and eggs.
The temperature range that bed bugs can survive depends on the species of bedbugs. Heat-resistant eggs need temperatures of 125 degrees Fahrenheit and above. Infested objects can be safely baked for three to five hours at temperatures that are high enough to kill the bugs. However, care must be taken to ensure that the treatment does not cause harm to the people or pets. Other methods of heat treatment include the use of frozen carbon dioxide sprays and heat distribution systems. These techniques require special equipment.
Heat treatment is one of the most effective methods for eliminating bed bugs. However, it should be used with caution as it may cause cold spots. This is because heat can cross over insulation and large objects. It is best to move furniture and other items out of the way so that the heat can penetrate the desired radius.
