“Don’t let the bed bugs bite” is a familiar bedtime phrase, usually meant in a playful context. Unfortunately, bed bugs are on the rise in the United States. These irritating pests are surprisingly hardy and can survive in extreme conditions, including freezing temperatures.
Can bed bugs live in the cold?
Yes. Bed bugs have a high cold tolerance. They can remain active at temperatures as low as 46 degrees Fahrenheit, and they can survive at even lower temperatures. They’re able to lower the freezing point of their bodily fluids, allowing them to live in the cold for a few days. Research published in the Journal of Economic Entomology found that some bed bugs survived short exposure to temperatures as low as -13 degrees F. However, if they’re exposed to extreme cold (below 0° F) for several days, they will die.
>Can bed bugs freeze?
Yes. The Journal of Economic Entomology study found that bed bugs freeze when exposed to 3.2 degrees F for 80 hours. It's a function of time and temperature. The lower the temperature, the shorter period of time it takes to freeze a bed bug. For example, at 32 degrees F, it could take weeks. At 30 below 0 F it could be minutes. Terminix's RapidFreeze treatment instantly takes the bed bugs to minus 60 to 80 degrees below 0 F and kills them instantly.
Will freezing bed bugs get rid of them?
Yes. Freezing bed bugs can kill them. However, you have to use a very low temperature (0 degrees F or colder) for at least four days for cold treatment to work. Your freezer may not even be cold enough. The center of the item, such as bedding, being frozen must reach 0 degrees F. Use a remote thermometer to measure the temperature of the items you’re freezing. Begin counting the four days as soon as the center reaches 0 degrees F.
Is freezing bed bugs the best way to get rid of them?
Yes and no. You can try to freeze bed bugs, but the best way to control bed bugs is through Integrated Pest Management—a combination of prevention, monitoring and treatment. Some bed bugs have become resistant to common pesticides, meaning many bed bug sprays are no longer effective. Heat and steam, using professional equipment, can also be used to treat bed bugs.
Many professionals do freeze bed bugs effectively, but in a much different way. They use specialized equipment that generates tiny particles of "snow" from carbon dioxide, the same material that puts the "fizz" in soft drinks. For bed bugs, these tiny ice crystals are deadly. The "snow" leaves no harmful residue on clothing, bedding or other sensitive items, so thorough treatment can be performed.
