Tent Fumigation — Quick Facts
Why Fumigation in Ontario?
High subterranean risk from agricultural soil history and irrigation.
In Ontario, drywood termites commonly establish multiple colonies across different structural members. When infestation is widespread or located in inaccessible areas like attic framing, tent fumigation eliminates everything in a single treatment.
All tent fumigation 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 valley homes experience extreme seasonal temperature swings that drive drywood termites deep into wall and attic framing during summer. Fumigation is particularly effective for these widespread, heat-driven infestations that span multiple structural members.
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.

Tent Fumigation in Ontario takes approximately 3 days. 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 tent fumigation the right choice for my Ontario home?

How long do I need to be out of my home?
Typically 3 days (2 nights). You drop off a house key, we handle the rest. You return once our inspector confirms safe clearance levels.
Is Vikane gas safe?
Yes — Vikane (sulfuryl fluoride) is a registered pesticide used in millions of California fumigations. It leaves zero residue after the required aeration period and is tested by EPA and CARB.
Do I need to wash everything after fumigation?
No. Food items in hard-sealed containers (cans, bottles) do not need to be removed or washed. Items in soft packaging (chips, bread) should be bagged or removed per the prep checklist.
Will fumigation prevent termites from coming back?
Fumigation eliminates the current infestation completely but leaves no residual barrier. Annual inspections are recommended to catch any new colonies early.
