Liquid soil treatment is the traditional line of defense against termites — a chemical barrier that has to meet a federal efficacy standard, not just get sprayed and forgotten. Call (404) 647-6677 for a free evaluation.
How liquid soil treatment works
A liquid treatment establishes a chemical barrier in the soil around and beneath a structure, so termites can’t cross it to reach the wood above. Where a full barrier isn’t practical — cavity walls, voids under a slab, earth-filled porches — foaming is often used instead. As UGA Extension describes it: “Foaming is an application technique used to deliver termiticides to areas where voids exist within elements of construction. The advantage of foam is that it expands to fill wall and sub-slab voids and cavities, resulting in treatment of most surfaces.”
The EPA standard behind soil termiticides
Termiticides used for soil treatment aren’t judged the way ordinary pesticides are. The EPA’s own labeling policy sets a specific bar: “soil treatment termiticide products should demonstrate efficacy for at least five years against termites.” That standard exists because short-lived products create more risk, not less — the EPA notes “the Agency will generally not grant a registration for a termiticide that requires annual retreatment.” In other words, a product that needs treating every year is a product the EPA generally won’t approve for this use in the first place.
That doesn’t mean treatments last forever. UGA Extension is direct about this too: “Soil-applied termiticides degrade as they age.” That’s why most termite control contracts eventually call for a “booster” treatment — reapplying the barrier once the original has broken down, typically at the end of a contract term. Georgia regulates how that’s billed, too: “In Georgia, companies cannot charge for a booster treatment without first issuing a new contract.”
Retreatment — and when it’s free
If termites return after an initial treatment, that’s not automatically a new bill. UGA Extension notes plainly: “Routine or annual retreatment(s) without cause is (are) not permitted” — retreatment under an active contract has to be triggered by actual evidence, like continued swarming, new shelter tubes, or live termites found in the structure, not scheduled on a calendar.
How Georgia enforces treatment quality
Georgia doesn’t just take a pest control company’s word that a treatment was done correctly. The state’s enforcement agency can inspect treated properties and collect soil samples to verify the work. Per the Commission’s own rule, if testing within six months of treatment finds termiticide residue below the required threshold, “the entire structure shall be retreated by the licensee within thirty (30) days after notification to the licensee by the Enforcement Agency” — at no cost tied to the original under-treatment. That’s a real regulatory backstop behind the five-year efficacy standard, not just a manufacturer’s promise.
Our termite treatment process
- Inspection. We identify current activity, entry points, and the construction details that determine how treatment needs to be applied.
- Treatment plan. Depending on what we find, that’s a full barrier treatment, a defined/spot treatment to a specific area, or foam for voids and slab cavities.
- Application. Soil is trenched and treated along the foundation; voids, expansion joints, and under-slab areas are drilled and treated or foamed as needed.
- Documentation. You get a diagram and record of what was treated and how — the same documentation Georgia’s enforcement agency can request.
- Retreatment terms. Your contract specifies what triggers a free retreatment if termites return before the barrier is due for a booster.
Common questions
How long does a liquid treatment last?
Federal policy requires registered soil termiticides to demonstrate at least five years of efficacy against termites — that’s the baseline a treatment is built around, not a marketing number.
Will I need retreatment every year?
No — the EPA generally won’t register a termiticide that requires annual retreatment in the first place, and Georgia doesn’t permit routine or annual retreatment without cause. Retreatment happens when there’s actual evidence termites are back.
What’s the difference between a full treatment and a spot treatment?
A full (comprehensive) soil treatment establishes a chemical barrier around the entire structure. A defined or spot treatment targets a specific area — typically where an active, localized infestation was found — rather than the whole perimeter.
Is liquid treatment safe to be around?
Termiticides used for structural treatment are EPA-registered products, applied according to their label directions. For specific safety questions about a product being used at your home, ask for the product label — it has the EPA’s own directions for use.
What happens if termites come back after treatment?
If there’s evidence of renewed activity — new shelter tubes, continued swarming, or live termites in the structure — that’s grounds for retreatment under most contracts, generally at no extra cost during the contract term.
Prefer a bait system instead?
Liquid treatment isn’t the only option. See Termite Bait Systems for how monitoring-based baiting compares.
Already have termite damage?
Treatment stops the infestation — it doesn’t repair what’s already damaged. See Termite Damage Repair. Not sure if you have an active problem? Start with a Termite Inspection.
