A Q&A With Field Scientists for the Sentricon® System: Part 1

Scientist Profile


A compilations of interviews with Sentricon field scientists (past and present:) Michelle Smith, Dr. Joe DeMark, Dr. Joe Eger and Dr. Barb Nead-Nylander.

One of the primary factors in the success of the Sentricon® Termite Colony Elimination System is the amount of real scientific research that is represented in every bait station installed.  We recently had the opportunity to speak with some of our field scientists, and they answered some questions about our product, termites, and how the Sentricon System utilizes science to be more environmentally friendly.

Q: What is the proof that the Sentricon System eliminates termite colonies?

A: Colony elimination with the Sentricon System is documented in 30 independent university and contract research studies, and more than 60 published scientific articles. Success also is reflected by more than 19 years of real-life success on over two million homes. A bibliography includes references from the top scientific articles concerning field and laboratory testing of Sentricon in relation to termite behavior and efficacy. These published articles provide extensive credibility to support the claims of Sentricon, and no one else in the industry has this kind of scientific support for termite bait.

Published scientific articles undergo anonymous peer review, and the paper must be detailed enough so experiments can be repeated to ensure the conclusions are consistent. Dow AgroSciences employees have authored some of the articles in the bibliography, but many of the articles are written by university and independent researchers. Researchers have been submitting journal articles on aspects of the Sentricon® System since the mid-1990s.

Q: When referring to the Sentricon System, what is the basis for calling it “environmentally responsible?”

A: Noviflumuron, the active ingredient in the Sentricon System, is contained in a tamper- resistant station and can be removed if desired. Rather than saturating the soil with a liquid chemical solution, Recruit® termite bait, used in Sentricon, is contained in the station and doesn’t leach or volatilize. The science behind Recruit termite bait exploits termite biology and behavior. Worker termites readily transfer the bait throughout the termite colony with the end result being total colony elimination.

The premier bait used in the Sentricon® System was the first product registered by the U.S. Environmental Protection Agency under the strict requirements of the Reduced Risk Pesticide Initiative. This distinction was based on its low impact on human health, low toxicity to non-target organisms (birds, fish and plants) and low potential for groundwater contamination when compared with other commercially available termite treatments.

The Sentricon System also is the only termite control product ever to have earned the Presidential Green Chemistry Challenge Award. The award is one of the federal government’s top environmental honors, and recognizes technical innovation that incorporates environmentally responsible chemistry into its design, manufacture and use.

Q: How long does a queen termite typically live?

A: While it depends heavily on the termite species and location, a queen termite can live a decade or longer, according to the Mallis Handbook of Pest Control. Queens have the longest life span when compared with workers and soldiers. However, a study* conducted on Coptotermes termites in Australia showed that when queens are exposed to Recruit termite bait, egg production declines first and queens can die within the first month. Eggs also stop developing and no longer hatch. Molting of the young larval stages, workers and nymphs are all affected, leading to colony elimination.

Q: What are the known foraging ranges for termites by species?

A: The foraging range can vary significantly based on the geography, soil type and species. Research papers* cited by the Mallis Handbook of Pest Control, available from the publisher of Pest Control Technology (PCT) magazine, state that Eastern subterranean termites can forage in areas up to one-third of an acre and up to 86 linear yards. Formosan subterranean termites had a foraging area of one half acre and foraging distances approaching 110 yards – similar to the length of a football field.

Swarm Season 2014—Reports From the Field

This year’s termite swarm season has been one for the record books. And thanks to the proliferation of smart phones, we’ve received lots of videos of termites and swarming. We thought we’d collect some of the best videos and show you what folks across the country have been experiencing this spring.



This video was taken by Amy Chapman, a sales rep for the Sentricon® System in the Southeast. Here’s how she tells the story behind this swarm: “I met a client today to look at a home with active termites in the basement. We spent time adding Recruit AG in the basement and when we went to leave, termites were swarming in the driveway.  We went searching for the source and found termites swarming out of two logs about 10 feet apart in the woods adjacent to her home.”



Shawn Varchetti, owner of D-Bug, Inc. in Latrobe, Pennsylvania, shot the video above. The termites entered the home through a window, and were in full swarm when the Certified Sentricon Specialist™ entered the basement. Luckily, Sentricon was installed and got to work right away.



Here’s an ugly reveal of what lies underneath old flooring during a recent home renovation! This video was sent in by Greg Sudholdt, a sales representative of the Sentricon® System. It occurred during swarm season in Louisiana. It’s a good reminder to let a pest professional thoroughly inspect your home—no matter its age—before you make any structural changes.



Want to see a swarm in action? This video was also sent in by Greg Sudholdt. That’s a new colony of Formosan termites on the move. Thanks to heavy rains and high humidity, Formosan swarms were plentiful in Louisiana and neighboring states this year.


Remember, if conditions are right, swarm season doesn’t stop with the end of spring. It can continue through the warmer months, too. The swarm lasts just a few minutes, so chances are better that you’ll see the wings they leave behind. Look for shed wings around windowsills, doors, heating vents, even bathtubs and sinks. Whether you see the swarm itself or the aftermath, it’s best to call a professional immediately. Better yet, why wait for the swarm? Your local Certified Sentricon Specialist can set you up with a termite protection program that will help prevent a termite problem.

The Sentricon(R) System Story

We thought that with swarm season just around the corner—or, depending where you live, arriving right now on your doorstep—we’d remind you how the Sentricon® System works to destroy not just one termite, but the entire colony. Swarm season occurs when newly developed reproductives leave the colony, shed their wings and attempt to create new colonies, so it’s important to understand why colony elimination is the best solution to your termite problem. “The Sentricon Story” video uses a quick-draw white board art technology to tell the tale!

Subterranean termites are social creatures, living in a highly organized caste system in an underground colony. Each caste member has a role, and they depend on each other for survival. The queen can lay millions of eggs in her lifetime. The king exists to reproduce with the queen. The soldier’s job is to protect the colony from invaders, like ants. Reproductives, or swarmers, are the termites with wings. When they’re ready, they emerge from the colony to begin new colonies. A colony can number from thousands of termites to millions, and it’s common to find two or more colonies competing for food around a property. The workers are responsible for feeding the colony by regurgitation, as other termites such as soldiers can’t feed themselves. Workers forage for food 24/7 by building tunnels and mud tubes from the colony to the food they find. Once they discover food, they mark it and their path to it with a pheromone—that’s a chemical they produce to communicate with each other. Termites can enter your home through an opening that’s as small as 1/32nd of an inch. If there’s a settlement crack, loose mortar joint, a small space around a drainpipe or a crack in your foundation, they’re in. And the damage begins.


The termite bait begins working the moment it’s put into the ground.   Just like a tree that expands its branches to absorb more sunlight, termites add additional tunnels off the main tunnels to maximize the colony’s chance of finding food. So naturally, they’ll find and begin feeding on the Sentricon bait stations. They can’t help it, it’s in their DNA! Their biology is why the bait—the science—the system—works. Once ingested, the patented active ingredient, noviflumiron, prevents the workers from molting. When they can’t molt, they die. And dead termites can’t feed their colony, so the colony dies. Because termites can’t detect noviflumiron, they continue feeding on the bait and deliver a lethal dose to the colony until it’s gone.


A Certified Sentricon Specialist™ will strategically place Sentricon stations about 10 feet apart around the perimeter of your home and in areas conducive to termite attack. He or she will check the stations and replace the bait when necessary, making sure it’s always working to prevent further attacks on your home. So every time you see those green stations, you can take pride in knowing that your home is being protected 24/7/365 by the product homeowners prefer over any other brand. That’s the science of the Sentricon® System—death to the queen, death to the termite colony—for good!


Tom Termite Takes Over During Termite Awareness Week!

From March 17th through the 23rd, 2014, the Sentricon® System promoted Termite Awareness Week.   However, at the beginning of the week, “Tom” Termite hacked into the Sentricon Twitter  account and proceeded to take over the tweeting duties. How did Sentricon eventually rid its social media of Tom? By doing what it does best—by utilizing scientific knowledge of termite behavior to eliminate the colony by ending the food supply chain they need for survival. In case you missed it, here is the timeline of Tom’s takeover, social media mischief, and ultimately his discovery of the bait station, which was his—and the colony’s–undoing:

But first, Tom posted this self-portrait:

And this was his first post:

He immediately went to work finding food for the colony…

Screen Shot 2014-03-26 at 5.44.39 PM

And shared some gossip.

Screen Shot 2014-03-26 at 5.45.05 PM

Eventually, Tom happened upon the Sentricon® System.

Screen Shot 2014-03-26 at 5.45.17 PM

He liked what was in the bait station so much he made a video:

Screen Shot 2014-03-26 at 5.45.34 PM

Tom complained a bit about his work.

Screen Shot 2014-03-26 at 5.45.44 PM

But overall, he seemed happy.

Screen Shot 2014-03-26 at 5.46.01 PM

Sometimes he shared too much information.

Screen Shot 2014-03-26 at 5.46.16 PM

The other worker termites got in on the good eats, too.

Screen Shot 2014-03-26 at 5.46.28 PM


However, it wasn’t too long before Tom felt something wasn’t right. Could it be that Sentricon was doing its job?

Screen Shot 2014-03-26 at 5.46.42 PM

And eventually, the entire termite colony started feeling the same way. So long, Tom.

Screen Shot 2014-03-26 at 5.46.55 PM


While Tom’s story may have been fictional, the effectiveness of the Sentricon® System is for real. Luckily, we were standing guard against Tom and the rest of the colony. Does Sentricon protect your space?








What Do the Queens of the Castle Think About the Sentricon® System? (Part 2)

For nearly twenty years, the Sentricon® System has protected homes just like yours. Here is Part 2 of our series of stories from the true “queens” of the castle. Find out what they think about Sentricon and the Certified Sentricon Specialist™ that helps protect their investment!

Laura, Dallas, Texas

laura from Dallas (2)

Laura decided to invest in the Sentricon® System for preventative reasons. “It’s not something that you want to be hit or miss. You want it taken care of. We don’t have to worry about what or how we’re going to afford to be able to repair the damage termites might cause. You don’t have to worry about where the next attack is going to be.”

Laney, Jackson, Mississippi

2013-05-18 06.31.31

Laney suffered through swarm season and then got the Sentricon® System installed. “It was an easy decision,” Laney declares. “The word around town from other people that have used it–I had already heard that they were pleased. “By the time that you find out that you’ve got termites, the damage can already be done before you see the evidence. It’s a must-have.”

Mandy, Virginia Beach, Virginia

2013-06-01 01.42.01

Mandy has been a loyal customer of her Certified Sentricon Specialist™ for over 15 years. When building a new home, she decided to get the Sentricon® System for preventative reasons. “After going through the trouble of building the house, decorating the house, the last thing I wanted was termite damage so there was no question. I like that it’s not just sticking a bunch of chemicals out into the environment, around my house, around my dog, around my children, around myself. It is truly an investment, not only in my house but also an investment with my family, an investment in my peace of mind. So many things can go wrong in a household. If I can eliminate one of them, I’m good.”

Clare, Monroe, North Carolina

2013-06-09 05.49.09

Clare is a busy dog lover that got the Sentricon® System for preventative reasons. “I don’t have to deal with it. It’s in the ground and boom. I don’t want to mess with chemicals or putting stuff all around the house. From my standpoint, not having to mess with it is great. I have two dogs and I don’t want to have to keep them away from wet stuff.”

Liquid or Bait? Watch our 3-D Video and Decide Which Method is Best

Our latest video goes 3-D with a termite colony. By going underground where termites live, you will get a feel for what termites want — to eat 24/7. See how the Sentricon® System works, and then learn about the differences between Sentricon and liquid treatments.


Subterranean termites that live in the soil are mother’s nature’s way of breaking down things like dead trees, yet they commonly invade homes like yours. Termites can’t tell the difference from the wood in your home from a dead tree. Your home might be your largest investment, but to a termite, it’s food!

Workers can forage for food nearly the length of a football field. Once food is found, they lay down a chemical trail of pheromones for others to follow. But even when a source is found, it’s the worker’s instinct to continue to search. So how do you protect your home and get peace of mind from this relentlessly foraging enemy? You have two options:



The objective of a liquid barrier is to create a continuous chemical barrier around the foundation of your home. When an individual termite comes into contact with the barrier, the termite dies. In order to apply an effective liquid barrier, it’s necessary to dig around your home’s foundation and in many cases, drill through concrete and brick to make the barrier continuous. This process takes several hours of preparation to apply potentially hundreds of gallons of termiticide. Even with this intense preparation, many things can obstruct the chemical barrier and limit the effectiveness of the liquid treatment, and a termite only requires 1/32nd of an inch to find their way through. Termites that contact the chemical barrier are killed, but liquid treatments degrade over time and aren’t designed to eliminate the colony, leaving your home vulnerable.


Versus Bait…

The Sentricon® System is a revolutionary product that uses the termite’s natural foraging instinct against them to eliminate their entire colony. Sentricon stations are professionally installed by a Certified Sentricon Specialist ™ and are strategically placed to be easily and quickly found by foraging termites. Remember, even when a food source has been found, the workers are constantly searching. And that constant search insures they will find a station. When they do, the workers distribute the bait into the hungry colony’s food supply. The bait is unknowingly passed from termite to termite. The workers die first and without workers, the rest of the colony cannot sustain itself. The entire colony is eliminated, including the queen. Sentricon offers around-the-clock protection from future colonies as well.

The termite colonies’ constant foraging makes liquid treatments vulnerable, but insures the success of the Sentricon® System. No digging, no structural drilling, just smart science. Sentricon is the only choice for true peace of mind and total termite colony elimination. Death to the termite queen, death to her colony, for good!


What Do the Queens of the Castle Think About the Sentricon® System?

The queen may be the heart of the termite colony, but a female homeowner puts her heart and soul into her home. If these two lock horns, who’s going to reign supreme? For nearly twenty years, the Sentricon® System has protected homes just like yours. Here are some stories from the true “queens” of the castle—find out what they think about Sentricon and the Certified Sentricon Specialist™ that helps protect their investment!

Laura, Dallas, Texas

Laura from Dallas part 1

Laura and her family kept seeing termites after liquid spot treatments. She says, “Living in Texas, they say you’re always going to have termites. The spot treatments were not working, so I decided to try something else. The reason why I am confident with it is that in the first inspection, there were termites in the station. So to me, that means it is working.”

Lynda, Virginia Beach, Virginia

Laura from Virginia part 1

Lynda is a homeowner that juggles multiple condominium properties. After dealing with termites invading several of the units, she decided to have Sentricon installed. “Mostly with me it’s environmental. It’s the most non-invasive. Termites ended after Sentricon.” Lynda is also satisfied with her Certified Sentricon Specialist. “You wouldn’t continue the contract more and more and more with someone if they didn’t give perfect service.”

Cindy, Southlake, Texas

Cindy from Texas part 1

Cindy is a hardworking homeowner that doesn’t have time for termites. “I work 24 hours a day, seven days a week and he [the Certified Sentricon Specialist] came to me and said that this worked, let’s do it…and that’s the way it went. It’s a system. It’s in there and it works. I trust [the technician] to take care of it and if there’s a problem, he will let me know.”

Natalie, Houma, Louisiana

Natalie from LA part 1

Natalie had Sentricon in her previous house. However, when she and her family moved to a different home, they found over $50,000 worth of damage. They immediately had the Sentricon® System installed on their new home after repairs. “It’s a proven system,” Natalie says. “It’s a sense of security you have knowing that it’s a great product and it’s covered and backed by reputable companies. We felt better the day we got Sentricon.”
