Termite Pressure Across the Inland Empire
The Inland Empire's hotter, drier climate produces a different termite picture than coastal Southern California. Without the marine layer humidity that drives drywood pressure at the coast, subterranean termites are the primary concern across the region — Rancho Cucamonga, Chino Hills, Ontario, and other heavily irrigated communities create the sustained soil moisture conditions subterranean colonies require. Our primary IE service area covers Chino, Chino Hills, Montclair, Ontario, Rancho Cucamonga, and Upland with free inspections; homeowners in other San Bernardino County cities — including Fontana, San Bernardino, Redlands, Rialto, and Colton — can schedule through our extended service area program. Across the IE, the species balance is typically reversed from coastal counties: subterranean is the dominant concern, drywood secondary.
The IE's hotter, drier climate produces a different termite picture than coastal Southern California. Without the marine layer humidity that drives drywood pressure at the coast, drywood activity is lower here. Subterranean termite pressure is the primary concern — Rancho Cucamonga, Chino Hills, and Ontario are heavily irrigated communities, and sustained soil moisture creates favorable conditions for subterranean colonies. Homes built in the 1990s and 2000s, which make up most of Rancho Cucamonga and Chino Hills, used pressure-treated lumber at foundation soil-contact points, but that treatment degrades over 15–25 years. A 1998 home in Rancho Cucamonga today has meaningfully reduced subterranean protection compared to when it was built.

Frequently Asked Questions About Inland Empire
Which Inland Empire cities does Ultimate Termite serve?
We serve six San Bernardino County cities as our primary Inland Empire service area — Chino, Chino Hills, Montclair, Ontario, Rancho Cucamonga, and Upland — with free inspections and standard scheduling from our Anaheim base. We also serve additional San Bernardino County cities including Fontana, San Bernardino, Redlands, Rialto, and Colton through our extended service area, where a $295 inspection fee applies and is fully credited toward any treatment you book. See our extended service area page for the full city list and how the two-tier service model works.
Are termites as prevalent in the Inland Empire as in coastal Southern California?
The IE's hotter, drier climate means drywood termite activity is somewhat lower than at the coast — the marine layer humidity that accelerates coastal drywood pressure isn't present here. But subterranean termite pressure is significant, particularly in newer communities with extensive lawn irrigation. Communities like Rancho Cucamonga and Chino Hills are heavily irrigated, and that sustained soil moisture creates favorable conditions for subterranean colonies. The species breakdown is typically reversed from coastal counties: subterranean is often the primary concern in IE inspections, drywood secondary.
Does the newer construction in Rancho Cucamonga and Chino Hills offer any termite protection?
Some, but limited. Homes built in the 1990s and 2000s — which make up most of Rancho Cucamonga and Chino Hills — used pressure-treated lumber at foundation soil-contact points, which provides initial subterranean protection. But chemical treatment in soil-contact lumber degrades over 15–25 years, so a 1998 home in Rancho Cucamonga has reduced protection compared to when it was built. Above-grade wood framing, eaves, and trim were never treated and remain susceptible to drywood termites. Age alone isn't a reliable indicator of risk.
How does the Inland Empire's summer heat affect termite activity?
Extreme summer heat can push termite activity underground or deeper into wood during the hottest months — termites avoid surface temperatures that exceed roughly 100°F. But colony growth doesn't stop; it just shifts timing and depth. For IE homeowners, this means visible signs of surface activity may be less obvious in July and August. Fall and spring inspections — when temperatures moderate — tend to surface more findings than mid-summer inspections. If you're scheduling an annual inspection, September through November or March through May are optimal windows in the IE.
