How Long Does It Take For Heat Bedbug Treatment To Work?


Managing an infestation of bed bugs may be an upsetting and stressful situation. Fortunately, there are various methods to eradicate these pests, one of which is thermal remediation or heat treatment. While this method is highly effective, one common question that homeowners have is: How long does bed bug heat treatment take to work? In this article, we will delve into the process of bed bug heat treatment, the factors influencing its duration, and what to expect during and after the treatment.

Understanding Bed Bug Heat Treatment

An environmentally benign and non-chemical method of bed insect extermination is bed bug heat treatment, which is sometimes called thermal remediation. To kill bed bugs while keeping people, pets, and property safe, the temperature of the contaminated area is heated to a certain point. To eradicate bed bugs and all their life phases, including eggs, nymphs, and adults, the temperature is usually increased to about 120-140°F, or 49-60°C, for a few hours.

Factors Influencing Treatment Duration

The duration of bed bug heat treatment can vary depending on several factors:

  • Infestation Severity: The length of time the treatment takes is mostly determined by the amount and intensity of the infestation. Smaller infestations may be resolved more quickly than larger, more extensive ones.
  • Room Size: The size of the room or area being treated directly affects the time required. Larger spaces may take longer to reach the desired temperature and maintain it uniformly.
  • Temperature Settings: The chosen temperature and the time it takes to reach and maintain it are essential considerations. Higher temperatures may work faster but require careful monitoring to avoid damage to sensitive items.
  • Preparation: Preparing the space before treatment is crucial. Removing clutter, sealing cracks and crevices, and ensuring proper insulation can help expedite the process.
  • Technician Expertise: The experience and expertise of the pest control technician conducting the heat treatment can also impact its efficiency and speed.

Typical Duration Of Bed Bug Heat Treatment

Heat treatments for bed bugs might take anywhere from six to twelve hours to finish on average. It’s important to remember that this time can vary greatly depending on the previously listed circumstances. This is an outline of the standard course of treatment:

  • Preparation: Before the heat treatment begins, the homeowner or Pest Solutions Termite and Pest Control professionals will prepare the area. This involves removing or covering items that could be damaged by high temperatures, sealing cracks, and ensuring the room is ready for treatment.
  • Heating: Once the preparation is complete, the heating process commences. Powerful heaters are strategically placed throughout the space, gradually raising the temperature to the lethal range for bed bugs. This phase can take several hours.
  • Maintenance: Maintaining the high temperature is critical to ensure the effective extermination of bed bugs. Technicians will continually monitor the temperature and adjust the heaters as needed. This phase can also take several hours.
  • Cooling Down: After achieving the desired temperature for a sufficient duration, the heaters are turned off, and the space is allowed to cool down. Cooling may take a few hours.
  • Post-Treatment Inspection: Once the room has cooled down, a post-treatment inspection is conducted to confirm the elimination of bed bugs. If necessary, follow-up treatments may be recommended.

What To Expect During And After Treatment?

During a bed bug heat treatment, residents must vacate the treated area, along with any pets, plants, and heat-sensitive items. Heat-resistant items, such as electronics, may need to be removed or appropriately protected.

During the treatment, you may experience some discomfort due to the elevated temperature, but it should not be unbearable. The process is safe when performed by experienced professionals who follow proper protocols.

After the treatment, it is crucial to follow the recommendations of the pest control team. They may advise on cleaning and reorganizing the space, as well as potential follow-up inspections to ensure the infestation is completely eradicated.


One non-chemical option for getting rid of bed bug infestations is bed bug heat therapy. It works quite well. Treatment times range from six to twelve hours, though this might change based on variables including the size of the space and the intensity of the infestation. Success hinges on being well-prepared and utilizing the knowledge of skilled specialists. Seeking the advice of a professional pest control firm that specializes in heat treatment can be an effective and long-term solution to the problem of bed bugs in your house.
