Heat Treatment — Quick Facts
Why Heat Treatment in Orange?
Mix of old and new construction, active drywood season in spring.
Heat treatment works well in Orange's climate because the entire structure can be brought to lethal temperature in a single day. It's especially valued by homeowners with pets, organic gardens, or chemical sensitivities who want a zero-residue solution.
All heat treatment services in Orange are performed by our CA-licensed inspector (License #PR7791) and come with a written report, warranty documentation, and a free inspection before any treatment is recommended.
Inland valley homes that already experience extreme summer heat are natural candidates for heat treatment. The process is highly effective in these climates, and same-day turnaround means minimal disruption even for larger inland homes. Pre-1970 homes often have plaster walls, original hardwood floors, and vintage finishes that some homeowners prefer not to expose to fumigation gas. Heat treatment provides whole-structure coverage with no chemical concern — though heat-sensitive items must still be removed.
Peak termite swarm season in Orange: April–June. Don't wait for visible damage — early treatment costs a fraction of structural repairs.
Inspector Note — Orange
“Old Towne Orange homes often have original basement or raised-foundation construction — always inspect the crawlspace fully and note any evidence of historical fumigation (secondary bolt holes, old staining) to gauge prior treatment history.”

Termite Conditions in Orange
The city of Orange has one of the oldest preserved historic downtown cores in OC, and Old Towne's Craftsman and Victorian homes from the 1890s–1920s represent the highest-risk structures in the city. Original old-growth Douglas fir framing in these homes supports large drywood colonies, while the flood control channels bisecting older neighborhoods create subterranean entry points near aging foundations.

Frequently Asked Questions
How much does heat treatment cost in Orange?
Heat Treatment in Orange typically costs $1,200–$3,500. The exact price depends on the size of your home, the extent of infestation, and accessibility. We provide free on-site inspections with a no-obligation written estimate before any work begins.
How long does heat treatment take in Orange?
Heat Treatment in Orange takes approximately 6–8 hours. You will need to vacate the property during treatment and may re-enter once our inspector confirms clearance. We schedule promptly and work around your availability.
Is heat treatment the right choice for my Orange home?
Heat Treatment is best suited for drywood termite problems. Orange homes face year-round termite pressure from both species. After your free inspection, our licensed inspector will confirm whether this is the right treatment for your specific situation.
Do you offer heat treatment throughout all of Orange?
Yes — Ultimate Termite serves all neighborhoods in Orange and the surrounding areas of Orange County. Whether you're near the center of Orange or on the outskirts, we can schedule a free inspection and treatment promptly. Call (714) 240-2800 or schedule online.
Can I return home the same day?
Yes. Unlike fumigation, heat treatment is completed in 6–8 hours and you return home the same evening. No overnight stay is required.
What items need to be removed before heat treatment?
Remove candles, aerosol cans, medications, plants, and heat-sensitive electronics. We provide a full prep list — most homeowners find it much shorter than fumigation prep.
Is heat treatment as effective as fumigation?
Yes — when performed correctly, heat treatment achieves 100% termite mortality throughout the structure. Temperature sensors verify that all areas reach lethal exposure levels.
Does heat treatment work for subterranean termites?
Heat treatment is primarily effective for drywood termites. Subterranean termites in soil around the foundation require Termidor liquid barrier treatment.
