Bed bugs are resilient pests that can survive in the tiniest of crevices, making them notoriously difficult to eradicate. One of the most effective solutions is heat treatment, a method that utilizes lethal temperatures to eliminate these pests in all life stages.
Unlike pesticide treatments, heat penetrates hard-to-reach areas and provides a thorough cleanse without harmful residues. In this blog, discover how heat treatment can be the ultimate solution against bed bugs.
How does heat treatment for bed bugs work?
Heat treatment for bed bugs involves using electric or propane heaters to elevate room temperatures to around 135°F. The process includes blowing hot air into the room for several hours, monitored by sensors to reach at least 113°F in all areas, which is the appropriate temp to kill bed bugs. Most electronics can withstand high temperatures used in heat treatments.
To effectively kill bed bugs with heat, the lethal temperature must be maintained for over 60-90 minutes to exterminate the eggs successfully. Fans create convection currents, amplifying heat distribution and killing the pests.
Heat treatments are non-toxic, chemical-free, and suitable for commercial spaces like schools and hospitals where the use of chemicals may not be allowed. The entire thermal bed bug treatment process takes approximately 6-8 hours from setup to completion.
How to treat bed bug-infested items?
Treating bed bug-infested items can be challenging since insecticides aren’t suitable for most household objects. However, heat therapy principles used for rooms also apply to smaller items like bedding, clothes, and footwear.
For effective treatment, use a dryer on the high setting for 30 minutes or more to kill all bed bugs and their eggs. For delicate items such as leather shoes, handbags, and books, use a dryer with a removable shelf. Adjust the drying time as needed to reach the thermal death point for guaranteed eradication.
How much does bed bug heat treatment cost?
Expect to pay $1200 or more, depending on the size of the infested area and the extent of work required to solve the pest infestation problem. The bed bug thermal treatment cost will always depend on the specificities of each project, and no two jobs will likely cost the same.
Pricing for residential and commercial applications will also vary, mainly due to the size of the treatment area. Potential clients or homeowners should consult with professional bed bug heat treatment exterminators to get the best price match for their needs.
Pros and Cons of Heat Treatment for Bed Bugs
Similar to steam and chemical treatments, heat extermination for bed bugs also has its own benefits and potential drawbacks. However, it’s currently the safest and one of the most effective treatments, especially for serious infestations. Knowing its pros and cons can help you decide whether or not heat therapy for bed bugs is the right option for you.
| Pros | Cons |
| Non-toxic and chemical-free | Relatively expensive compared to other treatments |
| No need to remove or bag most belongings | Time-consuming process (6-8 hours) |
| Cures most infestations with a single treatment | No residual treatment activity; possible reinfestation if not done properly |
| Effective against pesticide-resistant bed bugs | Limited availability of professional exterminators carrying specialized equipment |
| Safe for electronics if managed correctly | Combustible and heat-sensitive food items must be removed from the treatment area |
| Suitable for sensitive environments like schools | Older buildings may have heat sinks requiring complementary chemical treatment methods |
Preparation for Heat Treatment
Without proper preparation of the infested space, the chances of reinfestation soar. Before exterminators begin the heat treatment, home and building owners are expected to do a few things to maximize the potency and effectiveness of the treatment.
Declutter the Area: Remove clutter from the infested areas to allow heat to penetrate all spaces effectively. This includes under beds, inside closets, and behind furniture.
Move Sensitive Items: Remove heat-sensitive items such as food, medication, candles, crayons, and cosmetics. These items can melt or be damaged by the high temperatures used during treatment.
Secure Electronics: Unplug all electronics and make them accessible for the treatment process. Temperatures generated during the treatment process will not damage electronics, but it’s best to monitor them closely.
Laundry: Wash and dry all bedding, clothing, and fabrics at high temperatures. Set the dryer on high for at least 30 minutes, using heat to kill bed bugs present.
Open Furniture and Storage: Open drawers, closets, and other storage units to ensure heat can reach inside. This includes dresser drawers, nightstands, and other furniture.
Remove Pets and Plants: Remove all pets and plants from the treatment area. High temperatures can be harmful to living organisms not involved in the treatment process.
Monitoring Equipment: Technicians will place temperature sensors throughout the area to monitor the heat distribution. Make sure they have clear access to place and check these sensors.
Clear Out Combustible Items: Remove all combustible items, such as lighters, oxygen tanks, and aerosols, to prevent potential hazards.
Keep Bed Bugs Away for Good
Post-treatment steps are essential to prevent bed bug reinfestation. Start by using bed bug-proof encasements for mattresses and box springs to trap any surviving bugs and block new ones from infesting your bedding.
Permanently seal any cracks and crevices in walls, floors, and furniture to eliminate potential hiding spots, and exercise caution when introducing second-hand furniture, mattresses, or clothing into your home.
Finally, schedule a follow-up inspection with your exterminator to confirm the treatment’s success and handle any remaining issues. Many companies offer warranties or money-back guarantees with follow-up services free of charge for added assurance.
