Sentricon: The Science-Backed Termite Solution That Eliminates the Entire Colony
Every year, termites cause an estimated $6.8 billion in property damage across the United States — more than fires, floods, and stormsUnderstanding the Enemy: How Subterranean Termites Work
To understand why Sentricon works so well, you first need to understand how subterranean termites operate.
Eastern subterranean termites (Reticulitermes flavipes) — the dominant species in Missouri and throughout the eastern United States — live in underground colonies that can number in the hundreds of thousands, sometimes millions. Worker termites forage constantly and relentlessly, traveling distances greater than 100 yards in search of cellulose-based food sources: wood, paper, cardboard, and the structural framing of your home.
The colony’s survival depends entirely on its workers. Workers forage, feed, and return to the colony to share food with nestmates — including the queen and soldiers who cannot feed themselves. This behavior, called trophallaxis, is the key biological mechanism that makes the Sentricon bait system so devastatingly effective.
A queen termite can produce more than a million offspring in her lifetime. Colonies routinely contain multiple reproductives, and it is not uncommon for multiple colonies to attack a single home simultaneously. This is not a pest you can simply “treat around the edges” and hope for the best.
The Old Approach: Liquid Barrier Treatments
For decades, liquid termiticide treatments were the industry standard. The approach is straightforward: drill into the soil around your home’s foundation and inject a chemical barrier — typically a non-repellent insecticide like fipronil or imidacloprid — that kills termites as they attempt to pass through it.
Liquid treatments can work, and they remain a legitimate tool in the pest control toolbox. But they come with significant limitations that the science community has increasingly acknowledged:
They do not eliminate the colony. A liquid barrier kills individual termites that cross it — but the colony remains alive underground, continuing to reproduce. The source of the problem is never addressed.
They require complete perimeter coverage. Any gap in the chemical barrier — a crack in concrete, an untreated utility penetration, soil disturbance from landscaping — can allow termites to bypass the treatment entirely.
They degrade over time. Soil chemistry, water table levels, and microbial activity all break down liquid termiticides. Most manufacturers recommend retreatment every 5–8 years, requiring significant soil disruption each time.
They are environmentally intensive. Hundreds of gallons of chemical solution are injected into the soil around your home’s foundation, posing potential risks to groundwater, non-target soil organisms, and garden plants.
None of this means liquid treatments are worthless — but it does mean they are a reactive, perimeter-based solution rather than a systematic, colony-eliminating one.
What Is the Sentricon® System?
The Sentricon® system, developed by Corteva Agriscience (formerly Dow AgroSciences), is a colony elimination bait system. Instead of creating a chemical wall around your home, Sentricon works with termite biology to turn the colony’s own behavior against itself.
The system was introduced in 1995 and is now the No. 1 brand in termite protection, guarding millions of structures across the United States — including the White House, the Statue of Liberty, and Independence Hall.
It works like this:
A Certified Sentricon Specialist® (like our team at X Pest Management) installs a series of in-ground bait stations around the perimeter of your home, typically every 10 feet. Each station contains Recruit® HD termite bait — a cellulose matrix infused with noviflumuron, an insect growth regulator that prevents termites from successfully molting.
Worker termites, foraging constantly for food, discover the stations during their natural underground exploration. They find the bait highly palatable — in controlled studies, termites preferred Recruit® HD bait over wood — and begin feeding on it. Critically, they carry the bait back to the colony and share it with nestmates through trophallaxis.
As the active ingredient spreads through the colony, termites begin to fail at molting and die. The effect cascades through the entire population — soldiers, reproductives, and ultimately the queen. The colony collapses.
The current generation of Sentricon uses Always Active™ technology, meaning bait is present in the stations at all times — not just when active termite activity is detected. Your home is protected year-round, before termites ever have a chance to reach your structure.
The Science Behind Sentricon: Dr. Nan-Yao Su and the University of Florida Research
The intellectual foundation for the Sentricon system was built at the University of Florida’s Fort Lauderdale Research and Education Center, primarily through the decades-long research of Dr. Nan-Yao Su — one of the world’s foremost authorities on subterranean termite biology and control.
Dr. Su’s landmark 1994 paper, “Elimination of Subterranean Termite Colonies by Hexaflumuron Baits,” published in the Journal of Economic Entomology, first demonstrated the scientific viability of colony-elimination bait technology. His research established the core principle that termites’ own foraging and trophallaxis behaviors could be weaponized against the colony — a paradigm shift from barrier-based thinking. This research formed the scientific basis for Sentricon’s development.
Dr. Su and his University of Florida colleagues also conducted some of the earliest field validations of bait system efficacy, demonstrating complete colony elimination in replicated, controlled field trials. Their work was instrumental in earning regulatory acceptance and commercial development of the technology.
Building on Dr. Su’s foundational research, Dr. Thomas Chouvenc — also at the University of Florida — has continued advancing our understanding of termite colony dynamics, including research on colony size estimation, the structure of large subterranean colonies, and the factors that govern colony growth and vulnerability. His 2015 work on competitive dynamics between termite colonies (Chouvenc et al., 2015, PLOS ONE) and ongoing research into Formosan subterranean termite biology has further refined how scientists and pest management professionals understand colonial vulnerability to disruption — directly informing best practices in bait system deployment.
Collectively, the UF research body spanning more than three decades provides the scientific backbone for why colony-elimination bait systems represent a fundamentally superior approach to termite control compared to barrier treatments alone.
Real-World Efficacy: What the Studies Show
The Sentricon system is backed by more than 60 scientific studies and 30 independent research studies — a body of evidence that is unmatched among commercially available termite control products.
Key findings from the research literature include:
Colony Elimination Confirmed in Field Trials. Multiple peer-reviewed studies have demonstrated complete subterranean termite colony elimination following Sentricon bait deployment. Su et al. (1997) confirmed colony elimination using hexaflumuron-based baits in replicated field plots, establishing the real-world viability of colony-elimination as a primary treatment strategy.
Bait Palatability. Research has consistently shown that termites prefer the Recruit® HD bait matrix over untreated wood — a critical advantage. A bait system only works if termites feed on it. Studies evaluating foraging behavior demonstrate that termites fed on the bait at high rates and shared it effectively through the colony.
Noviflumuron’s Mode of Action. The active ingredient in the current Recruit® HD bait, noviflumuron, is a chitin synthesis inhibitor — an insect growth regulator that disrupts the molting process. Since termites must molt to grow and survive, exposure to noviflumuron causes colony collapse from within. Critically, because it works slowly and systemically rather than as a contact kill, termites do not detect its lethality and continue sharing it throughout the colony.
Long-Term Protection Data. Long-term monitoring studies have shown that properties maintained on the Sentricon program continue to show effective protection years after initial installation. The persistent presence of bait in Always Active™ stations ensures that recolonization by new colonies is intercepted before any structure damage can occur.
Effectiveness Against Active Infestations. The Sentricon system is equally effective as a curative treatment — when above-ground Recruit® AG stations are installed directly at active feeding sites, colony elimination can be achieved in as little as a few weeks to a few months, depending on colony size and foraging behavior.
Environmental Advantages: The EPA’s Presidential Green Chemistry Award
The original Sentricon system is the only termite control product ever to receive the U.S. Environmental Protection Agency’s Presidential Green Chemistry Challenge Award. This recognition — given for scientific achievement in environmentally responsible chemistry — reflects a genuine distinction in how the product interacts with the environment compared to conventional termiticides.
The environmental profile of Sentricon stands apart from liquid treatments in several ways:
Minimal active ingredient. Each Sentricon bait station contains only a small amount of active ingredient, placed precisely where termites forage underground. This contrasts sharply with liquid treatments, which require hundreds of gallons of chemical solution to be injected into the soil around a home’s entire perimeter.
Low toxicity to non-target organisms. Noviflumuron is specifically targeted at insects that molt — it has very low toxicity to mammals, birds, and most non-target insects. The active ingredient is not systemic in plants and poses extremely low risk of groundwater contamination due to the small amounts used and the targeted delivery mechanism.
No drilling, no disruption. Installing Sentricon requires no drilling into concrete or foundation slabs, no soil trenching, and no disruption to landscaping. The in-ground stations are installed flush with the soil surface.
Safe around vegetable gardens. According to Corteva Agriscience, it is safe to plant vegetable and herb gardens near Sentricon stations. The active ingredient will not be taken up by plants, and leaching risk is extremely low.
For homeowners who prioritize environmental responsibility — or who have children, pets, or gardens they’re concerned about — Sentricon’s environmental profile is a meaningful advantage.
Sentricon vs. Liquid Treatments: A Direct Comparison
Goal: Eliminate the entire colony
Sentricon: Yes — kills queen and all colony members through bait sharing
Liquid Treatment: No — kills individual termites crossing the barrier; colony survives
Disruption to Property:
Sentricon: Minimal — small in-ground stations installed with no drilling or trenching
Liquid Treatment: High — requires drilling into slabs, trenching around foundation, hundreds of gallons of chemical injection
Environmental Impact:
Sentricon: Low — targeted bait with minimal active ingredient; EPA Green Chemistry Award recipient
Liquid Treatment: Higher — large volume of chemical applied to soil around entire structure
Ongoing Service:
Sentricon: Annual station inspection by a Certified Sentricon Specialist®
Liquid Treatment: Barrier retreatment every 5–10 years required; significant disruption each cycle
Protection Model:
Sentricon: Proactive and continuous — Always Active™ bait intercepts termites year-round
Liquid Treatment: Reactive — barrier must be intact; any gap creates vulnerability
Scientific Evidence:
Sentricon: 60+ published studies; 30+ independent research studies
Liquid Treatment: Established efficacy but does not address colony elimination
The bottom line: liquid treatments repel or kill termites that reach your foundation. Sentricon eliminates the colonies that threaten it.
What to Expect When You Choose Sentricon with X Pest Management
As Certified Sentricon Specialists®, our technicians are specifically trained and authorized by Corteva Agriscience to install, service, and interpret the Sentricon system. Not every pest control company is authorized to use it — and this matters, because proper installation and ongoing monitoring are critical to the system’s effectiveness.
Here’s what the process looks like:
Initial Inspection. We conduct a thorough inspection of your property to assess termite pressure, identify any existing activity, and determine the optimal station placement strategy for your home.
Installation. We install in-ground Sentricon stations around your home’s perimeter, spaced approximately every 10 feet. Installation takes a few hours and requires no drilling, no trenching, and no disruption to your landscaping or foundation. You don’t even need to be home.
Ongoing Service. Per label requirements, stations are inspected at least annually. Our team documents bait consumption, monitors for activity, and replenishes bait as needed. You’ll receive service records and a clear picture of what’s happening on your property.
Immediate Response. If active feeding is detected inside your home, we can install above-ground Recruit® AG stations directly at the infestation site to accelerate colony elimination.
Curative or Preventative. Already have termites? Sentricon eliminates active infestations. Never had them? Sentricon keeps it that way. The system works identically as both a curative and a preventative treatment.
Sentricon is available through our X Termite plan (included with our X Premium and X Ultimate protection packages) or as a standalone service. We offer both preventative installation and curative treatment options.
The Bottom Line
Termites are patient, persistent, and invisible. By the time homeowners notice the signs — hollow-sounding wood, sagging floors, discarded wings near windows — the damage is already done. The average termite claim costs thousands of dollars, and most homeowners insurance policies don’t cover termite damage.
The Sentricon system doesn’t just manage termites — it eliminates the colonies responsible for the damage. It is the only termite product backed by over 60 published studies, the only one to win the EPA’s Presidential Green Chemistry Award, and the No. 1 brand in termite protection for a reason.
If you live in the Kansas City metro or Lee’s Summit area, termites are not a hypothetical risk — they are an active one. Subterranean termites are present in every county in Missouri.
Don’t wait for the signs. Get protected now.

In Missouri, subterranean termites are active in every county, silently consuming the structural wood of homes while homeowners remain completely unaware. The damage is rarely visible until it’s severe, and by then, the cost is catastrophic.
If you’re researching termite protection options, you’ve likely encountered two main categories: liquid barrier treatments and bait systems. For decades, liquid treatments dominated the industry. But the science has evolved — and one system, backed by more than 60 published studies and the EPA’s highest environmental honor, has redefined what effective termite control looks like.
That system is Sentricon®.
At X Pest Management, we’re proud Certified Sentricon Specialists®. Here’s what the science actually says — and why we believe Sentricon is the gold standard in termite protection.
