Can cold kill bed bugs?

Yes, cold can kill bed bugs. In fact, temperature-related bed bug control is becoming a popular solution for those looking to eliminate these pesky insects without the use of pesticides. Freezing temperatures can be particularly effective in killing bed bugs, as it dehydrates and ultimately kills them. Here are some key facts to know about using cold temperatures to get rid of bed bugs:

  • Place infested items in a sealed plastic bag – To effectively kill bed bugs with cold temperatures, you’ll need to place the infested item(s) in a sealed plastic bag first. This helps to prevent bed bugs from escaping or spreading to other areas of your home.
  • Set your freezer to 0°F – Your freezer should be set to 0 degrees Fahrenheit in order to properly kill bed bugs. Lower temperatures don’t necessarily guarantee success, so make sure you keep the temperature at or below 0°F.
  • Leave items in the freezer for at least 4 days – To kill bed bugs with cold temperatures, the infested items need to be left in the freezer for at least 4 days. This ensures that all bed bugs and their eggs are killed.
  • Use caution when removing infested items – Once the items have been frozen, be sure to handle them carefully when removing from the freezer. Bed bugs can still be alive but sluggish, so it’s important to avoid spreading them to other areas of your home.
  • While cold temperatures can be effective in killing bed bugs, it may not be practical for larger infestations or hard-to-treat areas. It’s always best to consult with a pest control professional who can provide guidance on the best course of action for your specific situation.

    Can Cold Kill Bed Bugs?

    Understanding the Bed Bug Infestation: A Brief Overview

    Bed bugs are tiny parasitic insects that feed on the blood of humans and animals. They usually infest bedding, furniture, and other household items, making them difficult to detect and eliminate. Bed bugs multiply quickly and can cause significant discomfort and embarrassment.

    An infestation starts with a few bed bugs, which then multiply and spread throughout the house. Bed bugs are highly resilient and can quickly develop resistance to pesticides, making it difficult to control them. Common symptoms of bed bug bites include red and itchy welts that can lead to severe allergic reactions.

    What is Temperature-related Bed Bug Control?

    Temperature-related bed bug control involves using hot or cold temperatures to eliminate bed bugs. Pest control professionals use several methods, such as heating up a room or freezing infested items, to eradicate bed bugs effectively.

    Freezing is a simple and cost-effective way of controlling bed bugs. It eliminates pests without the use of harmful chemicals, making it an environmentally friendly solution. Freezing involves placing infested items in a sealed plastic bag and freezing them at zero degrees Fahrenheit for about four days.

    How does Cold Kill Bed Bugs: The Science Behind It

    According to research, bed bugs can’t survive in extreme temperatures. When exposed to freezing temperatures, bed bugs’ bodies go into shock and eventually die off. The low temperature reduces the insect’s metabolism rate, causing them to become lethargic and die due to cell damage.

    The freezing process targets bed bugs at all stages of life, including eggs, nymphs, and adults. Because freezing is a non-chemical approach, bed bugs cannot build up resistance to it, unlike pesticides.

    Practical Steps for Freezing Bed Bugs: A Guide to Cold Treatment

    Freezing is an effective bed bug control method for items that are small enough to fit in a freezer, such as clothing, bedding, and pillows. Here are some practical steps to follow when using cold treatment to eliminate bed bugs:

    Step 1: Seal the infested item in a plastic bag and squeeze out all the air.

    Step 2: Place the sealed bag in the freezer set at zero degrees Fahrenheit.

    Step 3: Leave the item in the freezer for about four days to ensure all the bugs are dead.

    Step 4: After four days, remove the bag from the freezer and let it come back to room temperature before opening it.

    Step 5: Launder the items immediately to ensure that any dead bed bugs are removed.

    Advantages and Disadvantages of Cold Treatment: When is it Effective?

    Like any bed bug control method, cold treatment has its advantages and disadvantages. Below are some pros and cons of using freezing to eliminate bed bugs:


    • Non-toxic method of insect control
    • Environmentally friendly
    • Effective against all stages of bed bugs
    • Bed bugs cannot build up resistance to freezing
    • Cheaper than other bed bug control methods


    • Some items may be too large to fit in a freezer
    • Requires a specific temperature and duration of exposure to be effective
    • Takes longer than other bed bug control methods
    • May not reach bed bugs in hidden cracks and crevices
    • Not effective for large bed bug infestations

    Safety Precautions to Consider when Freezing Bed Bugs

    While freezing is a safe method of bed bug control, there are still some safety precautions to consider:

    1. Avoid Overcrowding: Avoid overcrowding the freezer by placing too many items in at once. Overcrowding can prevent the temperature from reaching zero degrees Fahrenheit, which can render the process ineffective.

    2. Avoid Damaging the Items: Protect your items from damage by sealing them in a plastic bag first. Also, avoid exposing the items to moisture before or after the treatment.

    3. Avoid Ingesting Frozen Food: Keep food away from the freezer to avoid any cross-contamination with the frozen items. Bed bugs may have been living in the item, and consuming the food can lead to health risks.

    Alternative Pest Control Methods: Comparing Cold Treatment to Other Options

    There are several other pest control methods for bed bugs, such as pesticides, steam treatments, and heat treatments. Below are a few comparisons between these methods and cold treatment:

    Pesticides: Pesticides are the most commonly used method for bed bug control. However, bed bugs can quickly develop resistance to pesticides, making them less effective. Additionally, pesticides can be costly and may pose health risks to humans and pets.

    Steam Treatments: Steam treatment is an effective method of bed bug control, as the high temperature kills bed bugs at all stages of life. However, steam treatments can be expensive and may not reach bed bugs hidden in crevices.

    Heat Treatments: Heat treatments involve raising the temperature of a room or an item to kill bed bugs. This method is effective, but it may be costly and may require professional equipment.

    Conclusion: Can Cold Control Bed Bugs?

    Cold treatment is an effective and non-toxic method of bed bug control. It kills bed bugs at all stages of life and does not contribute to chemical resistance. Freezing is also a cost-effective solution compared to other bed bug control methods.

    However, cold treatment may not be suitable for large bed bug infestations or items that are too large for the freezer. Additionally, proper safety precautions must be considered before and after the treatment.

    Overall, cold treatment can be effective in controlling bed bugs and is a valuable tool in the fight against bed bug infestations.
