When dealing with a bed bug infestation, we tend to try all sorts of home remedies to get rid of these pesky critters. One such remedy is leaving your belongings outside under the hot sun for a few hours, hoping that the high temperatures would kill off the bed bugs. But, will it actually work? This burning question has been the subject of many debates among homeowners and pest control experts alike. In this article, we will explore the science behind this theory and find out whether the hot sun is indeed a bed bug killer. So, sit tight and be ready to have your mind blown.

Will the hot sun kill bed bugs?

Many people wonder if exposing bed bugs to direct sunlight is a feasible method for eradication. Well, the answer is yes! Exposing bed bugs and their eggs to direct sunlight can indeed kill them. Here’s how it works:

  • Firstly, if you have any objects that are infested with bed bugs and can be removed from your home, like clothing, bedding, or small furniture, you can place them outdoors in direct sunlight.
  • Make sure to cover the objects with black garbage bags to prevent the bed bugs from escaping and to intensify the heat.
  • Depending on the weather conditions, the sun’s rays can raise the temperature within the bags to a sufficient degree to kill bed bugs as well as their eggs.
  • It’s important to note that this method may not be effective if the weather is cloudy, overcast, or too cold.
  • Additionally, this method may not work if the objects are too large or numerous as there needs to be enough direct sunlight to penetrate and heat the objects thoroughly.
  • In conclusion, exposing bed bugs and their eggs to direct sunlight can be a useful tool for eradication, but it should be used in conjunction with other methods such as vacuuming, steaming, and professional pest control services.

    Pro Tips
    1. Use heat treatment to kill bed bugs in your belongings: While the hot sun may not be enough to kill bed bugs in your home, heat treatment can be an effective way to eliminate them from your belongings. Place items in a dryer on high heat or use a specialized heat treatment device to ensure all bed bugs are eliminated.

    2. Don’t rely on the hot sun as the sole means of bed bug control: While the hot sun may be effective in killing bed bugs in certain situations, it cannot eliminate an entire infestation in your home. Use additional methods such as vacuuming, pesticides, and professional pest control services for a comprehensive approach.

    3. Avoid leaving items outside in the hot sun: Bed bugs can survive extreme temperatures and may simply move to another area of your belongings if they are left in the hot sun. Additionally, leaving items outside can attract other pests and increase the chances of further infestations.

    4. Be cautious of bringing infested items into your home: Whether it’s thrift store finds or items from a friend’s home, bringing in infested items can lead to a bed bug infestation in your own home. Carefully inspect any used items before bringing them inside, and consider heat treating them before use.

    5. Seek professional help for a bed bug infestation: If you suspect a bed bug infestation in your home, seek professional pest control services. Bed bugs can be extremely difficult to eliminate, and a professional can provide effective treatment methods and advice for keeping them out of your home in the future.

    Myth or Fact: Will the hot sun kill bed bugs?

    There is a popular belief that exposing bed bugs to direct sunlight will immediately kill them. However, scientific evidence suggests otherwise. The truth is that bed bugs are resilient pests that can survive in a range of environments and temperatures. While sunlight can harm bed bugs, it is not a foolproof method for eliminating them. Therefore, it is essential to explore the efficacy of sunlight exposure as an effective treatment method for bed bugs.

    Can sunlight exposure be an effective method for eliminating bed bugs?

    Sunlight exposure can be a useful method for eliminating bed bugs, but it is not a standalone solution for complete eradication of bed bugs from your living spaces. Research shows that exposing bed bugs to temperatures above 113°F for more than 90 minutes can kill both adult bugs and their eggs effectively. As such, using direct sunlight to heat bed bug-infested items can be a viable method of treatment if the correct precautions are taken.

    Advantages and disadvantages of using direct sunlight to kill bed bugs


    • Sunlight exposure is a natural and eco-friendly pest control solution that doesn’t require the use of chemicals or harmful pesticides.
    • It is cost-effective since sunlight is free and readily available in most areas.
    • Sunlight exposure can kill bed bugs and their eggs in a matter of hours which can limit the spread and recurrence of an infestation.


    • It requires clear and sunny weather conditions to be effective, and prolonged exposure to sunlight is not always possible.
    • Bed bug-infested items must be left outside, which can result in property damage, theft, or exposure to other pests or elements.
    • Sunlight exposure may not penetrate deep into the crevices where bed bugs often hide, which can lead to incomplete elimination of the infestation.

    How does direct sunlight kill bed bugs and their eggs?

    Direct sunlight can kill bed bugs and their eggs by raising the internal temperature of the infested items to a lethal level. Bed bugs and their eggs cannot survive temperatures above 113°F for more than 90 minutes. When objects are left outside in direct sunlight, the temperature inside can exceed 140°F, killing bed bugs effectively.

    Tips for using direct sunlight as a bed bug treatment method

    Step 1: Identify the infested objects that can be exposed to direct sunlight without being damaged.

    Step 2: Cover the objects with black garbage bags, ensuring that there are no holes or gaps that allow sunlight to escape.

    Step 3: Place the covered objects in a location where they receive direct sunlight for several hours.

    Step 4: Check the temperature of the objects periodically using a thermometer to ensure that they have reached at least 113°F for 90 minutes.

    Step 5: After treatment, inspect the objects to ensure that there are no live bed bugs or eggs remaining.

    Will weather conditions affect the efficiency of using sunlight to kill bed bugs?

    Yes, weather conditions can significantly affect the efficiency of using sunlight to kill bed bugs. Exposing bed bug-infested items to direct sunlight works best on clear and sunny days. The temperature inside covered objects must reach at least 113°F for at least 90 minutes to be effective in killing bed bugs. If the weather conditions are cloudy or overcast, direct sunlight exposure may not raise the temperature high enough to eradicate bed bugs.

    How to safely and properly expose bed bug-infested items to direct sunlight.

    When using direct sunlight to eliminate bed bugs, it is crucial to take steps to ensure your safety and avoid damage to your property.

    Step 1: Wear appropriate protective clothing, including gloves, long-sleeved shirts, and pants to avoid direct contact with bed bugs.

    Step 2: Handle infested items with care to avoid spreading bed bugs to other areas of your residence.

    Step 3: Cover infested items with black garbage bags to ensure that direct sunlight exposure can penetrate deep into crevices where bed bugs hide.

    Step 4: Position the exposed bags in direct sunlight, ensuring that the temperature inside reaches at least 113°F for at least 90 minutes.

    Step 5: After treatment, inspect the objects for live bed bugs or eggs. Dispose of infested items that cannot be effectively treated outside or inside your residence.

    In conclusion, direct sunlight exposure can be an effective pest control solution for eliminating bed bugs and their eggs. However, it is essential to follow the correct procedure, take the necessary precautions, and understand its advantages and disadvantages to maximize its effectiveness. If you continue to have bed bug problems, contacting a pest control professional is always recommended.
