Sentricon

The baiting technique employed by the Sentricon System takes advantage of termite biology and behavior. Subterranean worker termites forage for cellulose food sources 24 hours a day, ranging abroad from their underground nest, or colony, through tunnels in the soil that can extend up to 300 feet or more. When worker termites find a food source, they leave a pheromone scent trail to summon nest mates.{{cite web|url=http://www.termites.com/information/facts/termite-behavior/|title=Termite Behavior|accessdate=2014-12-15}} Worker termites chew and digest cellulose, and then regurgitate it to share with other termites in the colony.{{cite web|url=http://science.howstuffworks.com/zoology/insects-arachnids/termite.htm|title=How Termites Work|date=11 September 2007 |accessdate=2013-06-14}}{{cite web| url=https://xtermites.com/|title=Termite Treatment }} Saturday, 19 January 2019

Sentricon bait stations are installed in the soil, creating a protective perimeter around a property. These stations are baited with a cellulose material impregnated with noviflumuron,{{cite web | url = https://www.icup.org.uk/media/gjjjozs2/icup238.pdf | title = Noviflumuron Activity in Household and Structural Insect Pests | author = M. S. Smith, L. L. Karr, J. E. King, W. N. Kline, R. J. Sbragia, J. J. Sheets, and M. Tolley }} a chitin synthesis inhibitor. When foraging, worker termites find the stations, eat the bait material, and then regurgitate it for colony nest mates to consume. Termites affected by noviflumuron later die as the compound inhibits molting and is its effects are inconspicuous to termites as to where it originates. As termites within the colony die, the colony is eliminated, typically over a period of months. Noviflumuron bait treatment requires less disruption of buildings and surroundings than traditional methods based on creating a barrier of termicide-treated soil around the structure to be protected, but noviflumuron bait treatment also needs to be continued indefinitely to prevent re-infestation in areas where termites are endemic.Michael Potter, Consumer Update: Termite Baits, U. of Kentucky college of Agriculture https://www.uky.edu/Ag/Entomology/entfacts/struct/ef644.htm

In 2000, the Sentricon System received the Presidential Green Chemistry Challenge Award, an environmental honor from the U.S. government.{{cite web|url=https://www.epa.gov/greenchemistry/presidential-green-chemistry-challenge-2000-designing-greener-chemicals-award|title=Presidential Green Chemistry Challenge: 2000 Designing Greener Chemicals Award|date=5 March 2013 |accessdate=2023-02-15}}

Sentricon has been extensively tested.{{cite web|url=https://autm.net/about-tech-transfer/better-world-project/bwp-stories/sentricon%C2%AE-termite-colony-elimination-system|title=Termite Colony Elimination System: Termite Control Without Using Toxic Insecticides|accessdate=2023-02-15}} Multiple independent research studies have shown that its bait matrix and baiting technique is an effective termite control option.{{cite web|url=https://nature.berkeley.edu/upmc/documents/sentricon_suppression.pdf|title=Large-scale Suppression of a Subterranean Termite Community Using the Sentricon Termite Colony Elimination System: A Case Study in Chatsworth, California, USA|accessdate=2023-02-15}}{{cite web|url=https://blogs.ifas.ufl.edu/news/2018/02/22/uf-study-shows-termite-bait-works-scientists-can-improve/|title=UF study shows why termite bait works and how scientists can improve it|date=22 February 2018 |accessdate=2023-02-15}} Field evaluations have documented the elimination of subterranean termite activity, including that of Formosan subterranean termites, often within 3 to 6 months.

Ongoing monitoring and re-baiting is critical to termite colony elimination. Without proper oversight, re-infestation from neighboring foraging colonies can occur. However, such re-infestations have not included any members of the original colony. Long-term studies have shown that by implementing the recommended service frequency, approximately 60% of the colonies are eliminated during the first quarter, approximately 75% of the colonies are eliminated after the second quarter, and nearly all colonies are eliminated within a year of the initial baiting, with all colonies ultimately being eliminated.{{cite journal|url=http://www.bioone.org/doi/abs/10.1603/EC11027|title=Elimination of Subterranean Termite (Isoptera: Rhinotermitidae) Colonies using a Refined Cellulose Bait Matrix Containing Noviflumuron When Monitored and Replenished Quarterly|year=2012 |doi=10.1603/EC11027 |accessdate=2015-04-06|last1=Eger |first1=J.
