How heat treatment works
Bed bug heat treatment uses specialized heaters and fans to raise the air temperature of an infested room or entire home to 135-145°F and hold it there for several hours. Bed bugs die at sustained temperatures above roughly 120°F, and unlike chemical treatment, heat penetrates cracks, seams, and furniture where eggs are hidden — killing eggs as well as adult bugs in the same visit.
Why it's often preferred
The main appeal of heat treatment is speed and thoroughness: most jobs are completed in a single visit, typically within a few hours, with no waiting weeks for a multi-visit chemical plan to run its course. Because it works by temperature rather than pesticide, there's no chemical residue left behind afterward, which matters to households with young kids, pets, or anyone sensitive to pesticide odors.
Heat treatment typically runs $1 to $3 per square foot. In practice that works out to:
- A one-bedroom apartment: roughly $300-$650
- A whole single-family home: roughly $1,500-$6,200

Is heat treatment right for your situation?
Heat treatment tends to make the most sense when you want the problem resolved in one visit — for example, before a move-out date, in a rental with a tight turnaround, or when a household member reacts strongly to pesticide. If cost is the bigger constraint and you have more flexibility on timeline, chemical treatment may be worth a look too.
