5 Highlights on Subterranean Termite Treatment
Liquid barrier and bait station installation
Sterling Pest Control applies non-repellent termiticide around your foundation, footing, and crawl space to create a continuous chemical barrier that subterranean termites cannot detect or avoid. Worker termites carry the effective active ingredient back to the entire colony, which eradicates the nest completely.
Certified and licensed technicians
Every pest control operator on our team holds a current state applicator license and completes annual training in termite biology, termiticide label compliance, and integrated pest management protocols to help protect your property from pests.
Pre-construction and post-construction service
We treat new builds before the slab is poured and retrofit existing residential and commercial structures with perimeter trench and rod treatments, drill hole injections, and monitoring stations for all types of business and house construction.
Wood-destroying organism inspections
Our inspectors look at sill plates, joists, headers, subfloors, and framing to identify mud tubes, galleries, and termite damage. We access every area possible, and each client receives a detailed WDO report with photographs and a written treatment plan.
Transferable warranty and annual renewal
Every full subterranean termite treatment is backed by a service agreement with retreatment coverage, and we provide a free quote before any work begins. The warranty transfers to new owners, which makes it a trusted asset during real estate inspections and pre-purchase inspections.
Why Choose Our Subterranean Termite Treatment
Subterranean termite treatment is a specialized service that demands precision, the right chemistry, and deep knowledge of colony behavior. As an industry leader, Sterling Pest Control has built its reputation on delivering all three, and we know what it takes to get the best results.
We trench and rod around foundations, drill through concrete slabs, and inject termiticide at every plumbing penetration, expansion joint, and bath trap where termites penetrate structures – even areas with soil contact. Our technicians don’t guess. They use moisture meters, soil probes, borescopes, and thermal imaging cameras to seek out and locate active colonies before applying a single gallon of product.
Our treatment plans pair liquid soil treatment with bait-based monitoring. That dual approach means we eliminate the colony you have now and detect any new foraging activity before it reaches your wood. We place bait stations at measured intervals along your perimeter and return on a scheduled basis to keep your property well protected, inspect each cartridge, and swap bait matrices as needed.
Sterling Pest Control carries full commercial liability coverage and backs every job with a written warranty. If termites return during your coverage period, we retreat at no additional cost, saving you time and money. Our annual inspection program keeps that warranty active year after year, so call us to get started.
We serve both residential and commercial properties. Single-family homes, townhomes, apartment complexes, warehouses, churches – the scope changes, but the standard does not. You get a licensed, professional team that treats your structure like it matters, with tailored solutions done right. Because it does.
Signs You Need Subterranean Termite Treatment
A subterranean termite infestation is often concealed behind drywall, beneath subfloors, and inside wall cavities. By the time visible damage is found, the colony may have been feeding for months or years. Here are five warning signs that should raise concern and indicate you need professional treatment.
Mud tubes on foundation walls:
Subterranean termites build shelter tubes from soil, saliva, and frass to travel between their underground nest and your structure. These pencil-width tubes typically run down vertically along concrete foundations, piers, and crawl space walls. If you search and snap one open and see live worker termites inside, the colony is active.
Swarmers near windows and doors:
Winged alates emerge from mature colonies in spring and early summer. Finding dozens of discarded wings on windowsills, near light fixtures, or along baseboards signals a reproductive colony living in or very close to your structure. If you are looking at a swarm inside the building, it is a strong indicator of an established infestation.
Hollow or weakened wood:
Tap exposed joists, sill plates, and studs with a screwdriver handle. Infested lumber sounds hollow because worker termites consume the soft cellulose grain and leave a thin shell. Compromised, deteriorated framing can affect load-bearing capacity and create serious structural damage.
Bubbling or peeling paint:
Termite galleries running just beneath a painted surface trap moisture. That moisture-laden pocket causes paint to blister, buckle, or peel in patterns that mimic water damage. Learn to read these signs – a thorough probe behind the affected area often reveals active tunnels.
Sagging floors or sticking doors:
As termites devour subfloor sheathing, floor joists, headers, and even siding, the structural geometry shifts. Doors and windows bind in their frames. Floors feel spongy underfoot. These symptoms point to widespread, severe damage that requires immediate inspection and corrective treatment to solve the problem.
Our Subterranean Termite Treatment Process
Subterranean termite treatment at Sterling Pest Control follows a structured, repeatable process that leaves nothing to chance. We never skip a step because every detail matters to complete the job right.
Inspection and assessment.
A licensed inspector surveys the entire structure on the scheduled day. We examine the foundation, crawl space, basement, slab edges, attached porches, and garage. We check every mud tube, probe suspect wood, measure moisture levels, and document findings in a clean, formal inspection report with photographs.
Treatment plan and estimate
Based on the inspection, we draft a treatment plan that specifies the termiticide, application method, volume, and target areas as described. You receive a written estimate that details the scope of work, the products we will apply, and the warranty terms before getting started.
Trenching and rodding
Our technicians dig a narrow trench along the exterior foundation and put termiticide into the soil at label-rate concentrations. Where concrete walkways, patios, or driveways abut the foundation, we drill through the surface and rod-treat the low subsoil beneath.
Interior injection
We drill small holes through the basement or slab floor at expansion joints, plumbing penetrations, and bath traps. We inject termiticide under pressure, then patch off and seal every drill hole.
Bait station placement
We install in-ground monitoring stations around the perimeter at regular intervals. Each station contains a bait cartridge with a slow-acting insect growth regulator that worker termites of all species distribute throughout the colony.
Monitoring and maintenance
We come back quarterly or annually to inspect every bait station, check for new mud tubes, and verify the chemical barrier remains intact. Each visit is documented, and your warranty renews with continued service.
Brands We Use
Subterranean termite treatment products must meet strict EPA registration standards and carry clear label instructions for soil application, injection, and baiting. Sterling Pest Control selects only proven, professional-grade brands.
All products are applied strictly according to label directions by licensed applicators. We maintain current safety data sheets for every product on our trucks and provide them to clients on request.

FAQs About Subterranean Termite Treatment
What is subterranean termite treatment?
Subterranean termite treatment is a professional pest control service that eliminates active termite colonies living in the soil beneath and around a structure. Technicians apply liquid termiticide into trenches and drill holes going around the foundation and install bait stations along the perimeter. The goal is to kill the existing colony and create a lasting barrier that prevents reinfestation.
When should I schedule a termite inspection?
Schedule an inspection if you spot mud tubes, swarmers, discarded wings, or hollow-sounding wood. You should also get an inspection before purchasing a home, before selling a property, or if your structure has not been inspected in more than twelve months. Annual inspections catch new activity early, often within days of emergence.
Why do subterranean termites cause so much damage?
A single colony can contain hundreds of thousands to millions of worker termites. They forage around the clock, feeding on cellulose in wood, subfloor sheathing, and framing. Because they tunnel inside concealed spaces, the damage accumulates silently over months and years before being noticed, and structures are often left with severe harm.
How long does a subterranean termite treatment take?
A full liquid barrier treatment for an average residential home takes four to eight hours. Bait station installation adds one to two hours. The timeline depends on the structure’s size, foundation type, soil conditions, and the number of drill points and trenching sections required.
Can I treat subterranean termites myself?
Over-the-counter sprays and foam products kill termites on contact but do not reach the colony underground, except in rare cases. Professional-grade termiticides like fipronil and imidacloprid require specialized equipment, precise application volumes, and a licensed applicator to apply legally and effectively. DIY attempts typically fail to eradicate the colony and leave your belongings at risk.
Does the treatment harm pets or children?
Modern non-repellent termiticides are applied into the soil beneath and around the foundation, not inside living spaces. Once the product is injected and the drill holes are sealed, exposure risk is minimal. We follow all EPA label guidelines and can recommend specific re-entry intervals based on the products used at your property.
