Termite Inspection — Quick Facts
Why Inspection in Ontario?
High subterranean risk from agricultural soil history and irrigation.
In Ontario, both drywood and subterranean termites are active, but they require completely different treatments. An accurate inspection identifies exactly what species are present, where the infestation is concentrated, and which treatment will resolve it — so you don't pay for treatment you don't need.
All termite inspection services in Ontario 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 homes are inspected with special attention to attic framing, garage sill plates, and any wood-to-soil contact — areas most vulnerable to the combined subterranean and drywood pressure common in inland valley microclimates.
Peak termite swarm season in Ontario: March–May. Don't wait for visible damage — early treatment costs a fraction of structural repairs.
Inspector Note — Ontario
“Historic Ontario homes near Euclid Avenue often have original citrus-era irrigation channels converted to drainage beneath the property — these channels maintain chronic soil moisture and require special attention during the subterranean assessment.”

Termite Conditions in Ontario
Ontario is one of the Inland Empire's oldest cities, and its historic downtown district contains 1890s–1930s homes with original framing that carries significant drywood risk. More broadly, the city's agricultural soil history — once part of the Ontario Model Colony irrigation system — left a legacy of high soil moisture that sustains above-average subterranean termite pressure across virtually all residential areas, including newer development built on former grove land.
