Termites are one of the most destructive pests a homeowner can face. In the United States alone, they cause billions of dollars in structural damage every year – and most of it isn’t covered by standard homeowner’s insurance. That’s why proactive termite protection isn’t just smart, it’s essential.
Among the most effective tools in a pest control professional’s arsenal are in-ground bait stations. Rather than creating a chemical barrier around your home, bait stations lure termites in, expose them to a slow-acting toxicant, and allow worker termites to carry it back to the colony — eliminating the problem at the source. Two names consistently rise to the top of the industry: Sentricon and Annual Trelona. Both are highly effective, but they work differently and come with distinct advantages depending on your situation.
Let’s break down how each system works, what sets them apart, and how to know which one might be right for your home.
Sentricon is a termite baiting system developed by Corteva Agriscience (formerly Dow AgroSciences) and has been on the market since 1995. It is one of the most thoroughly researched and widely used termite control systems in the world, with decades of field data backing its performance.
Sentricon stations are installed in the ground around the perimeter of a structure, spaced roughly every 10 feet. Each station contains a cellulose monitoring matrix that attracts foraging termites. When termite activity is detected during routine inspections, the monitoring matrix is replaced with an Always Active™ bait containing noviflumuron – the active ingredient.
Noviflumuron is an insect growth regulator (IGR). It works by disrupting the molting process of termites. Because termites must periodically shed their exoskeletons to grow, noviflumuron prevents them from doing so successfully, causing them to die off over time. As worker termites carry the bait back to the colony, the active ingredient spreads throughout, ultimately collapsing the entire colony – including the queen.
Newer Sentricon stations contain bait at all times, even before termites are confirmed, providing immediate protection.
Sentricon has been used to protect high-profile structures including the White House and the Statue of Liberty.
Sentricon is only available through certified Sentricon Service Specialists, ensuring proper installation and monitoring.
The active ingredient targets only insects that molt (like termites), making it low-risk for mammals, birds, and the surrounding environment.
Regular inspections by your pest control provider ensure the system remains active and effective.
“How do I make these mosquitoes stop ruining my life without bathing my family in chemicals?”
Annual Trelona (also known as Trelona ATBS, or Advance Termite Bait System with Annual Stations) is manufactured by BASF. It was designed with a focus on simplicity and efficiency, making it a strong competitor to Sentricon in both residential and commercial settings.
Unlike some systems that require bait replenishment during every inspection visit, Trelona cartridges are designed to last a full year - reducing service visits and potentially lowering costs.
BASF's proprietary matrix is formulated to be highly palatable to termites, speeding up the initiation of feeding.
The station housing is built for long-term in-ground use and is resistant to soil conditions that could otherwise compromise effectiveness.
Pest professionals can efficiently inspect multiple stations per visit and only replace cartridges on the annual cycle unless heavy feeding warrants earlier attention.
Novaluron has a strong safety profile and specifically targets insects with an exoskeleton molting cycle, minimizing non-target impact.
