Does Cold Kill Bed Bugs?

Does Cold Kill Bed Bugs?

Do you remember that old saying, “Don’t let the bed bugs bite?” Well, what if they’ve already invaded your sacred sleeping space? Countless treatment methods claim to be the ultimate solution, but let’s focus on one that comes up time and again: cold temperatures. Specifically, we’re going to explore whether or not cold kills bed bugs and, if so, how to effectively use this treatment.

Will Cold Kill Bed Bugs?

The answer is both simple and complex - yes, but under specific conditions.

Contrary to popular belief, just opening your windows during winter won’t guarantee the death of bed bugs.

Types of Cold Treatment

The idea that cold can kill bed bugs isn't new, but the application of cold comes in various forms, each with its unique challenges and efficiencies. Let's delve into some of the most popular types:

Cryonite Treatment

This involves using carbon dioxide snow to freeze bed bugs instantaneously. The benefit of this method is that it’s chemical-free and can be applied on electrical outlets and other sensitive areas.

Deep Freezing

Items infested with bed bugs are placed in commercial freezers at extremely low temperatures. This is a more consumer-friendly approach but may not be practical for treating large areas.

Portable Cold Chambers

For larger items that can't fit into a freezer, such as furniture, portable cold chambers can be used. However, they may require specialized handling.

Liquid Nitrogen

Used primarily by professionals, liquid nitrogen can be applied to hard-to-reach areas. It’s extremely cold and can kill bed bugs on contact but is not suitable for direct application on most household items due to its extreme temperature.

Understanding the different cold treatments available can help you make an informed decision on the most suitable method for your situation.

How Cold Will Kill Bed Bugs?

The temperature has to plummet significantly.

Scientific Studies on Cold vs. Bed Bugs

Researchers indicate that a temperature of -18 degrees Celsius (0 degrees Fahrenheit) must be maintained for at least four days to ensure the extermination of bed bugs.

How Cold to Kill Bed Bugs?

The colder, the better, but there’s more to it.

Setting the Stage for Extreme Cold

How Long Does It Take for Cold to Kill Bed Bugs?

Time and temperature are critical.

The Duration Matters

A constant low temperature must be sustained for an extended period. Generally, at least 80 hours of exposure to -16 degrees Celsius (3 degrees Fahrenheit) is required for complete extermination.

How to Kill Bed Bugs with Cold

While the concept may seem straightforward, practically implementing a cold treatment to kill bed bugs is a multi-step process that requires careful planning. Below are some practical steps to guide you:

DIY vs. Professional Services

Costs Associated with Professional Services

Engaging a professional service ensures that the treatment is thorough and reaches all stages of the bed bug life cycle. However, it comes at a cost that may range from a few hundred to thousands of dollars depending on the severity of the infestation and the size of your home.


Before you engage in either DIY or professional cold treatment, preparation is essential:


The actual implementation of the cold treatment will depend on the method chosen:
