Heat Treatment — Quick Facts
Why Heat Treatment in Pasadena?
Many historic homes from early 1900s, very active drywood termite season.
Heat treatment works well in Pasadena'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 Pasadena 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 Pasadena: April–June. Don't wait for visible damage — early treatment costs a fraction of structural repairs.
Inspector Note — Pasadena
“Bungalow Heaven homes from the 1910s–1920s often have entire original attic framing packages — budget a full attic traverse, as large colonies can occupy 40–60% of the framing before any external signs appear.”

Termite Conditions in Pasadena
Pasadena is home to one of the highest concentrations of historic Craftsman bungalows in California, and the original old-growth Douglas fir and redwood framing in these 1900s–1930s homes carries some of the most substantial drywood termite infestations in the San Gabriel Valley. The combination of mature street trees, established garden landscapes, and aging infrastructure creates strong subterranean pressure beneath both historic and mid-century construction throughout the city.

Frequently Asked Questions
How much does heat treatment cost in Pasadena?
Heat Treatment in Pasadena 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 Pasadena?
Heat Treatment in Pasadena 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 Pasadena home?
Heat Treatment is best suited for drywood termite problems. Pasadena 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.

Yes — Ultimate Termite serves all neighborhoods in Pasadena and the surrounding areas of Los Angeles County. Whether you're near the center of Pasadena 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.
