How Long Does It Take To Eliminate Bedbugs With Thermal Remediation?

For both residential and commercial property owners, bedbug infestations are a nightmare. These microscopic, bloodsucking vermin can grow quickly and are notoriously hard to get rid of. While there are various methods for bedbug extermination, thermal remediation has gained popularity due to its effectiveness and eco-friendly nature. An inquiry that frequently comes up is, “How long does it take to eliminate bedbugs with thermal remediation?” To help you comprehend the timeframe for bedbug elimination with thermal remediation, we will examine some important factors in this piece as we delve into this topic.

Pre-Treatment Assessment

Before the thermal remediation process begins, a thorough inspection of the affected area is essential. Pest control professionals need to assess the extent of the infestation, identify hiding spots, and determine the most suitable equipment and treatment plan. This assessment can take anywhere from a few hours to a day, depending on the size and complexity of the infestation.

Preparatory Measures

Once the assessment is complete, the next step involves preparing the area for bed bug heat treatment. This includes removing any sensitive items that could be damaged by high temperatures, such as electronics, artwork, and certain chemicals. It may also involve disassembling furniture and other items to ensure that the heat can penetrate every nook and cranny where bedbugs might be hiding. The preparatory phase can take several hours or even a day, depending on the extent of preparation required.

The Treatment Process

Where the magic happens is during the thermal remediation therapy itself. To kill bedbugs, high-powered heaters are utilized to boost the afflicted area’s temperature to between 120°F and 140°F (49°C and 60°C). The length of the treatment relies on several variables, such as the size of the area, the level of infestation, and the tools being utilized. The usual residential room or hotel suite requires approximately 6 to 8 hours to finish the treatment.

Monitoring And Safety

Pest control experts keep a careful eye on the temperature throughout the treatment to make sure it stays within the intended range. Safety is a paramount concern during thermal remediation, and trained technicians take precautions to prevent damage to the property. This monitoring and safety phase can add a few additional hours to the overall treatment time.

Cooling And Post-Treatment Inspection

After the treatment phase, the area needs to cool down gradually before it can be reoccupied. This cooling period typically takes a few hours. Once the temperature has stabilized, a post-treatment inspection is conducted to confirm the effectiveness of the thermal remediation. This inspection ensures that all bedbugs and their eggs have been eradicated. The duration of this phase depends on the thoroughness of the inspection and may take a few hours.

Multiple Treatment Sessions

In some cases, a single thermal remediation treatment may not eliminate the bedbug infestation, especially if it is severe or if bedbugs have spread to adjacent rooms or areas. Pest control professionals may recommend multiple treatment sessions spaced several weeks apart to ensure complete eradication. This can extend the overall timeline for bedbug elimination.

Follow-Up And Prevention

To prevent recurrent infestations, preventive measures must be put in place even when thermal treatment is effective.  Pest control experts may provide recommendations for ongoing maintenance and vigilance. This includes sealing cracks and crevices, using bedbug-proof mattress covers, and maintaining a high level of cleanliness. Following these guidelines can help prevent a resurgence of bedbugs in the treated area.


Several variables can affect how quickly bedbugs can be eradicated using thermal remediation, such as the size of the infested area, the intensity of the infestation, and the thoroughness of the treatment. On average, it takes around one to two days from the initial assessment to the completion of the treatment and post-treatment inspection for a typical residential room. However, it is essential to understand that bedbug eradication may require multiple treatment sessions and ongoing preventive measures.
