Are bed bugs wreaking havoc in your home? Wondering if cold temperatures can help get rid of them? Let’s investigate! While chilly weather might be a promising solution for eliminating these pesky pests, it’s important to weigh the pros and cons before giving it a try. Keep reading to learn more about how bed bugs survive and thrive, and whether cold temperatures could be the key to finally getting rid of them.

What Temperature Kills Bed Bugs?

Heat Treatment

Look, heat treatment is the most effective way to kill bed bugs. Temperatures of no less than 120°F (48.8°C) must be sustained for a minimum of 60 minutes to effectively kill all stages of bed bug life cycles through heat treatment. Heat can penetrate into cracks and crevices where bed bugs hide, making it an ideal method for treating infestations that have spread throughout a home or building.

Cold Treatment

Cold treatments involve using freezing temperatures to kill bed bugs. Temperatures must reach 0°F (-17.7°C) in order to be effective against all stages of the life cycle; however, this type of treatment may not always work as some bed bugs can survive low temperatures by entering a state known as diapause or hibernation until conditions become more favorable again. This means that cold treatments may need to be repeated multiple times before they become completely successful at eliminating an infestation problem.

Key Takeaway: Heat treatments are the most reliable way to eliminate bed bugs completely. Still, it is essential to comprehend how bed bugs can endure in cold conditions and what alternate techniques may be employed for extermination.

Instead of Temperature, What About Insecticides?

Applying insecticides such as pyrethroids and neonicotinoids to target pests, which act on the nervous system of insects leading to paralysis and death when ingested or absorbed through their exoskeleton membrane, can be effective against adult populations. While these chemicals are highly effective against adult populations, they do not affect eggs so additional chemical applications will likely be necessary if there is evidence of egg-laying activity present in the area being treated with pesticides.

How Do Bed Bugs Survive in the Cold?

Bed bugs are resilient creatures and can survive in a wide range of temperatures. They can endure colder conditions by moderating their metabolic rate, enabling them to persist in chillier areas. Bed bugs try and seek out warmth from any source, such as people or other warm-blooded creatures, to stay heated. But when unable to do so, they can enter a dormant state in winter when temperatures dip, becoming sluggish and conserving energy until conditions become more suitable for survival.

Furthermore, they can seek shelter from the elements in places such as cracks and crevices found within walls or furniture where they can remain safe from sudden temperature fluctuations while still having access to food sources. By doing so, bedbugs are able to weather any kind of storm that Mother Nature throws at them without freezing over due to drastic changes between day/night temps.

Key Takeaway: Bed bugs are able to tough it out in the cold by slowing down their metabolism and seeking warmth from any available source.

Can You Use Cold to Get Rid of Bed Bugs?

Chilly temps can be employed to do away with bed bugs, but it is not always the most reliable strategy. Freezing infested items is one way to eliminate bed bugs, as temperatures below zero degrees Celsius will kill them. Nevertheless, this approach is only effective when all infested items are frozen simultaneously and for a prolonged duration. Lowering room temperature is another option; however, this approach takes a long time and may require special equipment above the normal air conditioners or dehumidifiers.

Freezing infested items requires that all affected objects be placed in a freezer set at -20°C (or lower) for several days or weeks depending on how cold it gets inside the appliance and how thick each item is.

Finally, Cryonite treatment can be used to freeze individual bed bugs with liquid carbon dioxide spray which has been shown to be more effective than simply lowering the room temperature. Cryonite treatment uses liquid carbon dioxide sprayed through nozzles onto individual pests, freezing them instantly while leaving behind no residue unlike chemical treatments do sometimes. So you don’t have to worry about any potential staining either afterward, plus it is safe to use around humans, animals, and pets alike since CO2 itself isn’t toxic whatsoever yet still very effective in killing both adult nymph and larvae stages dead upon contact.

Unfortunately, it is not really practical to treat large-scale outbreaks with a single unit as it does come at a bit of a pricey cost compared to the rest of the methods discussed above; this is the only real downside here despite being highly efficient overall.

Key Takeaway: Bed bugs are not fans of the cold, and while freezing-infested items are one way to kill them, it can be difficult if dealing with larger objects. Lowering room temperature takes longer but may still provide relief from an infestation. Cryonite treatment is a pricier option but highly efficient for killing individual bedbugs instantly without leaving behind any residue.

What Are the Pros and Cons of Using Cold to Kill Bed Bugs?

One of the main pros of using cold to kill bed bugs is that it’s a non-toxic method of control. Unlike chemical treatments, there are no toxic fumes or residues left behind when you use cold treatment on infested items. This makes it safe for humans and pets alike, which is great if you’re trying to keep your family safe from any potential harm.

Another pro is that this method can be used in conjunction with other methods of control such as vacuuming and steam cleaning.

On the downside though, using cold isn’t always 100% effective against bed bugs since they have been known to survive even subzero temperatures by entering into a state called diapause where they essentially hibernate until conditions become more favorable again. Additionally, some materials may be damaged by freezing temperatures so care must be taken when treating them with this method – especially electronics and fabrics. Finally, special equipment may need to be purchased in order for this type of treatment to work properly which could add up over time if multiple applications are necessary for complete eradication.

Key Takeaway: Low temps can be an economical, safe, and successful approach to eradicate bed bugs but it is not guaranteed. While cold treatments may work in conjunction with other methods like vacuuming or steam cleaning, they’re not a silver bullet since the pests could enter diapause when exposed to extreme subzero temperatures and some materials might sustain damage from freezing too.


Ultimately, it appears that cold temperatures are not favorable for bed bugs, using the cold to get rid of bed bugs may be difficult since most homes are unable to reach such low temperatures for an extended period of time. Therefore, while cold treatment may be an option to consider in some cases, it is usually best to seek the help of a professional pest control service that specializes in heat treatments for more reliable results. Heat treatments will provide you with the best chance of eliminating them completely.

FAQs in Relation to Do Bed Bugs Like the Cold

What temperature do bed bugs hate?

Bed bugs can only tolerate temperatures between 46°F (8°C) and 113°F (45°C); beyond this range, they will usually perish.

Do bed bugs prefer heat or cold?

Bed bugs prefer warmth and are most active at temperatures between 70-80°F. They can survive in colder climates but become dormant and inactive until the temperature rises again.
