Termite Treatment Methods

How do I know which treatment I need?

The starting point is always species. Drywood termites (confirmed by frass pellets near wood, or by inspection) call for fumigation if the infestation is widespread, or a localized method — orange oil, heat, spot treatment, microwave, or electro-gun — if it's contained. Subterranean termites (mud tubes at the foundation) almost always call for a Termidor liquid barrier in the soil. From there, the four questions higher on this page narrow it down: how widespread is it, can you vacate, any chemical concerns, what's your timeline. When in doubt, a free inspection gives you a written recommendation with no obligation to proceed.

Can I do a one-time treatment and be done with termites for good?

No treatment prevents future infestations indefinitely. Fumigation eliminates every termite inside the structure on treatment day but leaves no residual — a new colony can move in months or years later. Termidor liquid barrier has a 10+ year residual in the soil, which gives long-term protection against the same subterranean colony and new ones trying to cross the treated zone. Borate applied to bare wood during construction or remodel makes that wood inhospitable to termites for decades — but it has to be applied before drywall and paint go up. The honest answer: annual inspections are the only real long-term protection mechanism. They catch new infestations before they become expensive. Most of our clients combine a one-time treatment with an annual inspection for the ongoing coverage.

How long can termites stay in my wood if I don't treat them?

Indefinitely, and the damage compounds. Drywood termite colonies grow slowly — a new colony takes 3–5 years to produce its first swarmers — but an established colony can occupy your framing, eaves, and furniture for decades without visible structural failure, right up until it isn't. Subterranean termites are faster; a mature colony can consume a linear foot of wood per day. In Southern California, we regularly inspect homes where an untreated infestation has caused $20,000–$50,000 in structural damage. Treatment at early detection is almost always a fraction of repair cost later.

What if termites are in places we can't reach for spot treatment?

Inaccessibility is exactly when fumigation or heat treatment earns its cost. Tent fumigation with Vikane gas reaches every void, wall cavity, attic joist, and piece of furniture in the structure simultaneously — it doesn't need physical access to galleries. Heat treatment raises an entire room or zone to lethal temperature, killing termites in wall voids and framing without drilling. If an inspector determines the infestation is too distributed or deep for localized treatment, fumigation is typically the recommendation — not because it's the most profitable option, but because spot-treating inaccessible areas gives you a false sense of resolution while the colonies survive.

Do you guarantee termites won't come back?

We warranty the treatment, not the property's future. Here's the distinction: a fumigation warranty covers re-treatment if live termites are found during a re-inspection within the warranty period — typically 2 years. It doesn't mean termites can't re-enter from outside. Orange oil and spot treatment carry 1-year warranties on treated areas. Termidor's warranty covers the treated soil zone, typically 1 year with annual renewal options that reflect its long residual. No treatment permanently seals a home against new termite colonies — termites swarm, fly, and establish from outside every spring and fall. Annual inspections are how you catch re-infestation early, before damage accumulates.

What's the difference between treatment and prevention?

Treatment eliminates an active infestation. Prevention is about reducing the conditions that attract termites and catching new colonies before they establish. Preventive measures: eliminate wood-to-soil contact around the foundation, fix moisture problems (subterranean termites are drawn to damp wood), remove wood debris from the perimeter, keep attic and crawl space ventilation adequate. On the treatment side, borate applied to bare wood during construction or remodel is the closest thing to a built-in preventive — it makes the wood itself inhospitable to termites for decades. But for a home that's already built, annual inspections are how you catch new colonies before they become real damage. Catching a new colony at year one costs a few hundred dollars. Catching it at year five may cost tens of thousands.

Are termite treatments safe for pets and children?

Depends on the method. Fumigation requires removing all people, pets, and plants — re-entry is only authorized after a licensed inspector tests clearance levels, at which point it's safe. Orange oil, heat, microwave, and electro-gun present minimal chemical exposure risk; no evacuation is required. Termidor is applied to soil around the exterior foundation with very low indoor exposure risk. Spot treatment involves pesticide injection into wood — standard precautions apply but no evacuation is required. If you have specific medical sensitivities or concerns, mention them when scheduling and we'll prioritize non-chemical options where the infestation allows.

What if I see termites again after treatment?

Call us. If live termites appear within your warranty period in a treated area, we'll inspect and re-treat at no charge. If the activity is in a new area, or the warranty period has passed, we'll inspect to determine whether it's a new infestation, a colony that wasn't fully eliminated, or something else. Warranty work and new infestations are different things: a new colony entering from outside isn't a treatment failure, but it is something we'll diagnose clearly and quote before doing anything. Don't wait — termite damage accumulates, and what's a spot treatment job today can become a fumigation job in two years.
