Moderate RiskTermite Control in Chino Hills, CA
California-licensed termite inspectors serving Chino Hills and all of San Bernardino County. Free whole-structure inspections, honest treatment recommendations, and every method available — from orange oil to tent fumigation.
Chino Hills was incorporated in 1991 and its newer master-planned construction generally carries lower termite risk than adjacent older cities. However, the hillside topography creates HOA irrigation runoff that keeps soil moisture elevated near foundations throughout the residential corridors, and the city's proximity to the OC/LA county lines means it sits in a zone where drywood swarming activity from neighboring coastal and inland cities regularly introduces new colonies.

Termite Risk in Chino Hills
Chino Hills was incorporated in 1991 and its newer master-planned construction generally carries lower termite risk than adjacent older cities. However, the hillside topography creates HOA irrigation runoff that keeps soil moisture elevated near foundations throughout the residential corridors, and the city's proximity to the OC/LA county lines means it sits in a zone where drywood swarming activity from neighboring coastal and inland cities regularly introduces new colonies.
Warm Climate Year-Round
Chino Hills's mild temperatures allow termite colonies to remain active throughout the year — unlike colder climates where activity slows in winter. There is no "off season" for termites in Inland Empire.
Aging Wood Structures
Chino Hills homes average 20–35 years old, with common construction including Master-planned hillside single-family homes and condos, 1990s–2010s construction. Older wood framing, fascia, and eaves are more susceptible to drywood termite infestation, especially where paint or sealant has deteriorated.
Irrigation & Soil Moisture
Lawn irrigation and landscaping around Chino Hills homes keep soil moisture high near foundations — ideal conditions for subterranean termites, which travel through soil to reach wood. Foundation areas, crawlspaces, and soil-to-wood contact points are especially vulnerable.
Dense Housing
In densely-developed areas like Chino Hills, termite swarmers from neighboring properties can easily establish new colonies in your home. A neighbor's treatment can even push colonies into adjacent structures.
Inspector Note — Chino Hills
“Chino Hills hillside homes with canyon-facing rear yards often have subterranean activity at the downhill foundation wall — always probe the lowest-elevation foundation face first.”

Termite Activity Patterns in Chino Hills
Chino Hills homes — with an average age of 20–35 years — have construction features that create specific entry points for termites. Knowing the local patterns helps you catch activity before it becomes structural damage.
Frass / Droppings
Small hexagonal pellets resembling sawdust below eaves, window frames, or baseboards — drywood termite waste and a definitive sign of active infestation. In Chino Hills homes, this is one of the clearest visual indicators a colony is active inside the structure.
Mud Tubes
Pencil-width tunnels of mud along foundation walls, exterior surfaces, or pipes — subterranean termite travel highways built to maintain moisture from soil to wood. In Chino Hills, foundations and crawl spaces are a particularly important inspection target.
Hollow-Sounding Wood
Structural wood that sounds hollow or papery when tapped — termites have consumed the interior while leaving a thin shell. In Chino Hills, where typical homes are 20–35 years old, this test is a critical part of any thorough inspection — especially in attic beams, window sills, and floor joists.
Swarmers — Peak: April
Winged termites emerging from walls or near windows indicate a mature colony nearby. In Chino Hills, swarming typically peaks in April — shed wings on windowsills are a common early warning.
Also watch for: kickout holes (1mm holes where drywood termites push frass out of galleries) and blistering paint (subterranean tunneling through wall framing introducing moisture). Schedule a free inspection — most active infestations are confirmed within the first 30 minutes on site.
Termite Treatments Available in Chino Hills
We offer every proven treatment method. After a free inspection, our licensed inspector recommends the right approach for your specific infestation and home type.
Tent Fumigation
The most thorough drywood termite treatment. The entire structure is tented and fumigated with Vikane gas, eliminating all drywood termites throughout the home. Required for severe or whole-house infestations.
Tent fumigation details →Orange Oil Treatment
A no-tent alternative using d-limonene (orange oil) injected directly into termite galleries. Effective for localized drywood infestations. No need to leave home. Eco-friendly and low-odor.
Orange oil treatment details →Heat Treatment
The structure or specific areas are heated to 135–150°F, killing all termites and eggs without chemicals. Effective for drywood termites and can treat the whole structure without tenting.
Heat treatment details →Termidor / Liquid Treatment
A perimeter soil treatment using Termidor (fipronil) that creates a protective zone around the foundation. Highly effective for subterranean termites. Long-lasting and transfers through the colony.
Termidor liquid barrier details →Dry Rot Repair
Licensed dry rot inspection and repair — moisture source diagnosis, structural and cosmetic wood replacement, and optional Bora-Care protection for repaired areas.
Dry rot repair details →Bora-Care Treatment
Long-lasting preventive protection for wood framing using Bora-Care. Guards against termites, wood-boring beetles, and decay fungi — ideal for new construction, remodels, and post-fumigation protection.
