Heat Treatment for Termites — Chemical-Free
Thermal heat treatment raises the structure to 130–140°F, killing all termite life stages without any chemicals or fumigants. No tenting, no residue, and you can return the same day. Ultimate Termite provides professional heat treatment across Southern California.

How Heat Treatment Works
Thermal remediation uses propane-fired heaters to raise the internal temperature of the structure to 130–140°F. At these temperatures, all termite life stages — eggs, larvae, nymphs, soldiers, reproductives — are killed within minutes. The heat penetrates into wall voids, attic framing, and other areas that chemical spot treatments cannot reach.
Temperature sensors are placed throughout the structure and monitored in real time to ensure all areas reach lethal temperature while staying within safe limits for the building materials. The entire process takes 6–8 hours for most homes.
What to Remove Before Heat Treatment
Heat Treatment vs. Fumigation
| Factor | Heat Treatment | Tent Fumigation |
|---|---|---|

| Tenting required | No | Yes |
| Re-entry wait | Same day | ~3 days |
| Whole-house coverage | Yes | Yes |
| Works on subterranean | No | No |
| Residue | None | None |
| Cost range | $1,200–$3,500 | $1,500–$4,000 |
Frequently Asked Questions
How long does heat treatment take?
6–8 hours for most homes. You can return the same day once the structure has cooled.
Can heat treatment damage my home?
Properly monitored heat treatment is safe. Technicians use temperature sensors throughout the structure to ensure wood reaches lethal temperature without exceeding safe limits for the home.
Does heat treatment work on subterranean termites?
No — heat treats only inside the structure. Subterranean termites live in underground soil colonies and require a soil-applied liquid barrier treatment such as Termidor.
Is there any residue after heat treatment?
No — heat treatment uses no chemicals whatsoever. There is no residue of any kind. You can re-enter the same day.
How does heat compare to fumigation in cost?
Heat treatment is typically similar in cost to fumigation, ranging from $1,200–$3,500 for a whole home.
