Bed bugs are a persistent and unwanted problem in nearly every home. Being tiny, stealthy insects that use human blood as their source of sustenance, they can infest bedrooms, furniture, and other areas of the home in a matter of minutes, causing discomfort and sleepless nights. To eliminate bed bugs, people think: Does cold kill bed bugs? The idea of applying freezing temperatures as a natural, chemical-free way of eliminating them sounds appealing, but does it kill them? In this blog, we are going to look at the science of cold treatment of bed bugs and what you should know if you are considering using this method for pest control.

Findings About Bed Bugs and Why They Thrive

Let’s first examine their biology and how they can survive under extreme conditions. Bed bug control vancouver are highly resilient insects that are capable of surviving a sequence of environmental stresses. Bed bugs hide during the day in crevices, mattress seams, and furniture and come out during the night to feed.

One of the key secrets to their survival is that they can place themselves in a dormant state called diapause, especially at cold temperatures. This allows bed bugs to lower their metabolism and survive for extended periods of time without feeding, even months in some instances. Thus, merely placing them in the cold for some amount of time may not be enough to kill them completely

How Cold Affects Bed Bugs

Cold will kill bed bugs, but the temperature and length of exposure are critical. Researchers say bed bugs start to die when temperatures are at 0°F (-18°C).

Bed Bug Mortality and Freezing Temperatures

 

  • Short Exposure: Temporary short exposure to freezing temperatures, e.g., several hours in a home freezer (most typically about 0°F or -18°C), will kill adult bed bugs but may not be sufficient to kill eggs or all stages of bed bugs. 
  • Prolonged Exposure: It has been shown through experiments that to kill 100% of bed bugs, bed bugs would need to be exposed to temperatures of or lower than 0°F (-18°C) for four days (96 hours). The prolonged freezing ensures that even eggs, the most resilient stage, are destroyed. 
  • Slightly Higher Cold Temperatures: Slightly above freezing temperatures (32°F / 0°C) will slowly decelerate bed bugs and will kill them in the long run, but it will take weeks or months.

Using Cold to Kill Bed Bugs: Practical Applications

For residents or pest control professionals, cold can be a useful tool for bed bug control burnaby under specific circumstances, especially as part of an integrated pest management strategy.

Freezing of Items

Small items that cannot be chemically or heat-treated, such as clothes, toys, books, or electronic devices, can be placed in a freezer to kill bed bugs.

Tips for effective freezing:

  • Set the freezer temperature to 0°F (-18°C) or lower. 
  • Store infested items in the freezer for a minimum of 4 days. 
  • Pack the items in plastic bags to prevent moisture damage.


Freezing is chemical-free would be a healthy contribution, but it won’t typically be sufficient for the treatment of an entire infestation of bed bugs alone.

Survival of Bed Bugs in Cold Weather

Some people believe that bed bug control maple ridge can be naturally killed by the cold winter air. However, bed bugs prefer to remain warm inside. Even in outdoor spaces, they can find insulated hiding spots that protect them from freezing temperatures.

Research confirms that bed bugs can survive short periods in cold outdoor conditions but will eventually die if temperatures remain below freezing for several days.  In point of fact, bed bug control by relying solely on the cold winter is neither practical nor reliable.

Integrating Cold Treatment with Other Bed Bug Control Methods

To effectively kill bed bugs, it is recommended to combine cold treatment with other treatments, including heat treatments, chemical insecticides, vacuuming, and mattress encasements.

  • Heat Treatment: Heat will kill all life stages of bed bugs faster and more effectively than cold. Bed bugs are killed by temperatures of 118°F (48°C) or greater, maintained for 90 minutes or more. 
  • Chemical Control: Use of EPA-registered insecticides can help eliminate bed bugs from cracks, crevices, and hidden places. 
  • Physical Elimination: Vacuuming the infested areas and encasing mattresses and box springs keeps bed bug numbers under control.

Freezing items like clothing or bedding can complement these methods by ensuring that infested belongings don’t reintroduce bed bugs.

Summary: Does Cold Kill Bed Bugs?

Yes, cold kills bed bugs, but only under extremely specific conditions. Cold will kill bed bugs if temperatures are at or below 0°F (-18°C) for at least four days. This works well for small items and as part of a program for larger bed bug control. Cold treatment is not the final solution for extensive infestations.

If you realize you have bed bugs, the best thing to do is to seek professional pest control that will use proven, effective methods heat, cold, chemical, and physical treatment, that will be tailored to your situation.

Frequently Asked Questions

1. Can I put my entire mattress in the freezer to kill bed bugs?
Due to size and practical limitations, freezing a mattress is generally not feasible. Instead, mattress encasements and professional heat treatments are better options.

2. For how long do bed bugs survive at low temperatures?
Bed bugs survive for a few days to weeks at temperatures over freezing but die after 4+ days at sub-0°F (-18°C).

3. Does freezing kill bed bug eggs?
Yes, but this requires prolonged exposure (a minimum of 4 days) to very low temperatures.
