How to Kill Bed Bugs With Cold Temperatures

Bed bugs often reside in the mattresses and beds of homes. They are generally quite small and flat. If you have bed bugs, you must take steps to get rid of them. Otherwise, they can live in your bedding for months, living off your blood and waste. Thankfully, there are a variety of different treatment methods available to get rid of bed bugs. Bed bugs cannot survive extreme temperatures, so you can employ the use of cold temperatures to kill them.


Step 1

Soak your bedding in cold water. Fill a tub with cold water and place your bedding in it. Add ice to lower the temperature more. While bed bugs have difficulty surviving in temperatures lower than 55 degrees Fahrenheit, they are most effectively killed at temperatures lower than 32 degrees Fahrenheit.

Step 2

Place your mattress, bed frame and bedding outside in the winter. If you live in a cold climate, leave the items outside on a cold, dry night. The freezing temperatures should kill any bed bugs.

Step 3

Freeze your bedding. Place bedding in the freezer for one week. If you have access to an industrial freezer, you can also freeze the mattress and bed frame to effectively kill the bed bugs.

Step 4

Keep the air conditioner on its lowest setting. While most air conditioning units don't get cold enough to consistently kill bed bugs, they can produce temperatures that thwart egg production. Bed bugs are generally unable to produce eggs at temperatures below 55 degrees Fahrenheit.

Step 5

Be aware that there are other more effective ways to kill bed bugs. The use of cold temperatures is a somewhat unreliable method for killing bed bugs. Bed bugs cannot survive extreme heat, so you could wash your bedding in hot water. You can also vacuum your home to remove eggs and actual bed bugs. If all your methods fail, contact a professional exterminator to kill the bed bugs.
