Termidor® HE · Non-repellent · 10+ year residual
Pompano Beach liquid soil treatment

A non-repellent perimeter barrier that termites walk through — then carry back to the colony.

Termidor® HE liquid soil treatment is the workhorse subterranean control method in Florida — a continuous chemical barrier applied to the soil around your foundation that termites cannot detect, cannot avoid, and unwittingly distribute through the colony via trophallaxis. Ten years of residual protection in Pompano’s subtropical soil. Visit Pompano Termite Control for the company background.

Why non-repellent chemistry matters

The single biggest advance in termite control in the last forty years.

Up until 2000, every liquid termiticide on the market was repellent. The chemistry killed termites on direct contact and the surviving colony detected the treated zone and rerouted around it. That meant any gap in the treatment — a hairline crack in the slab, a missed inch of trench, a settled section of soil — became a re-entry route the entire colony eventually found.

Termidor® (fipronil) was the first non-repellent termiticide to gain widespread Florida deployment. Termites cannot detect it. They walk through the treated zone freely, pick up the active ingredient on their cuticles, return to the colony, and pass it through trophallaxis (mouth-to-mouth food sharing — the central social behavior of subterranean termites).

That difference completely changes the math:

  • Old repellent chemistry: the barrier stops foragers that contact it directly. Survivors avoid the treated zone. Colony continues.
  • Non-repellent Termidor® HE: foragers cross the barrier, return home, distribute the active ingredient through trophallaxis, and the colony itself collapses over weeks to months.

Termidor® HE (“HE” = High Efficiency) is the current formulation, requiring half the water volume of the original Termidor® SC and offering improved soil dispersion in clay and high-organic substrates. It is what we mix and apply on every job.

Trench specification

The labeled application — and the inches that matter.

1

Mark obstacles

Foundation walked, perimeter measured. AC condenser pads, irrigation lines, planters, hardscape penetrations flagged for drill-and-treat workarounds.

2

Excavate 6″ trench

Continuous 6-inch deep trench excavated against the foundation wall. Hardscape sections get pilot-drilled at 12-inch intervals.

3

Mix on-site, apply to label rate

Termidor® HE mixed at 0.06% finished concentration. 4 gallons of finished solution applied per 10 linear feet of trench, soaked into the soil.

4

Backfill, log, GPS-tag

Treated soil backfilled into the trench. Application photographed, GPS-tagged at the corners and at each hardscape penetration for the warranty record.

Hardscape, AC pads, and irrigation

How we treat the perimeter when you can’t trench it.

The protocol assumes continuous open soil against the foundation. Real Pompano homes rarely have that — most have a mix of mulched beds, concrete patios, paver walks, AC condenser pads, irrigation lines, and screened-in pool decks. Each obstacle requires a specific workaround:

  • Concrete patios & walks: 1/2-inch pilot bores at 12-inch intervals through the slab, termiticide injected to depth, holes plugged with color-matched concrete patch.
  • Paver patios: pavers lifted in a 6-inch border along the foundation, soil trenched and treated, pavers reset.
  • AC condenser pads: small soil sections cut around the pad legs, treated, restored. The unit itself never touched.
  • Irrigation lines: mapped before trenching, capped or detoured. We do not cut active irrigation.
  • Screened pool decks: screen removed in 6-inch sections along the foundation, deck slab pilot-drilled and treated, screen reset.

None of these workarounds reduce the protection level. The Termidor® HE barrier reaches the same depth and concentration regardless of what was above the soil before treatment.

When liquid is the right call

Six scenarios where we recommend Termidor® HE over baiting.

Open soil perimeter

Foundation surrounded by mulched beds and lawn — the easiest scenario. Trench, apply, backfill.

You want fast knockdown

Termidor® HE kills foragers within weeks vs Sentricon’s several months. Useful when active mud tubes are visible and you want immediate suppression.

No interest in annual fees

One-time application, 5–10 year warranty. No annual monitoring contract.

Heavy infestation, large yard

For multi-thousand-sq-ft properties with active subterranean tubes, the per-linear-foot economics favor Termidor® at scale.

Builder pre-construction follow-up

Post-construction Termidor® barrier maintains continuity with a pre-construction borate or soil-applied barrier from the original build.

Combination with Sentricon®

For Formosan and Asian subterraneans, Termidor® liquid is paired with Sentricon® baiting — liquid handles the perimeter foragers, bait collapses the colony.

The reduced-risk alternative

Altriset® (chlorantraniliprole) — when household conditions ask for less aggressive chemistry.

Termidor® HE is the default. Altriset® is the substitute. Altriset® uses chlorantraniliprole — a chemistry that targets the muscle-contraction system in termites (and is selective for arthropods that share that pathway). It holds the EPA reduced-risk classification, has a far lower toxicity profile for mammals and bees, and is approved for application around organic gardens.

The trade-off is speed. Altriset® takes longer to knock down the colony — workers stop feeding within hours, then die over several days — and the labeled residual is shorter than Termidor® HE’s ten-year benchmark. We recommend Altriset® for households with:

  • Koi or other ornamental fish in proximity to the foundation perimeter
  • Backyard chickens or other livestock
  • Extensive pollinator plantings adjacent to the foundation
  • Edible gardens within 10 feet of the perimeter
  • A homeowner preference for EPA reduced-risk chemistry, even at a price premium

Pricing typically runs $2 to $3 higher per linear foot than Termidor® HE.

Liquid soil treatment FAQ

What homeowners ask before the trench goes in.

What is liquid soil termite treatment?

A continuous chemical barrier applied to the soil around the foundation. 6-inch trench, Termidor® HE mixed at 0.06%, 4 gallons of finished solution per 10 linear feet. Termites walk through the treated zone unable to detect it, carry the active ingredient back to the colony, and spread it through trophallaxis.

How long does Termidor® HE last in Florida soil?

10+ years per manufacturer and third-party testing in subtropical Florida conditions. Backed by a 5-year retreatment warranty extendable to 10 years on annual inspection contract.

How much does liquid treatment cost in Pompano Beach?

$7–$12 per linear foot. Average 160-LF home: $1,400–$2,800. Altriset® reduced-risk substitute: $9–$14 per linear foot ($1,800–$3,200 typical).

Is Termidor® safe around pets and gardens?

Applied below grade and immediately backfilled — no surface contact. For households with koi, chickens, or extensive pollinator plantings near the foundation, we substitute Altriset® (EPA reduced-risk classification).

How long does the application take?

4–6 hours of on-site work for an average single-family home. You do not vacate. Lawn and beds disturbed minimally — only the 6-inch trench against the foundation.

Will the treatment damage my landscaping?

Mulched beds and lawn recover within weeks. Plants directly against the foundation may need to be moved temporarily if root systems extend into the trench area; we identify these during the inspection.

Can I combine liquid with bait stations?

Yes — and we do, for Formosan and Asian subterranean infestations. Termidor® HE handles the perimeter foragers within weeks, Sentricon® baiting collapses the colony over the following months. This combination protocol is the most aggressive subterranean approach we offer.

Mud tubes? Open soil perimeter? Termidor® is probably the answer.
