October 2005 - NASHVILLE, Tenn. – When pest management professionals arrive in Music City for PestWorld 2005, they will visit the 15th most termite-infested major city in the United States.
Since its inception 10 years ago, the Sentricon® [Hexaflumuron] Termite Colony Elimination System has been installed on more than 76,000 sites throughout the state, a number slightly less than the entire population of Tennessee when it became a state in 1796... At PestWorld 2005, Dow AgroSciences is sponsoring the Saturday Opening General Session, where attendees will have the opportunity to hear keynote speaker Tom Ridge, former Homeland Security Advisor. 
The Dow AgroSciences booth, themed “Don’t Gamble on Termite Control,” will feature Texas Hold‘em poker and other related activities and giveaways.  Visitors to the booth will have the opportunity to learn about Dow AgroSciences entire portfolio of products, including Vikane® gas fumigant and Halo™ Electronic Termite Detection.

Subterranean Termites. Part 2, by Caroline Cox
Journal of Pesticide Reform / Summer 1997. Vol. 17, No. 2

Hexaflumuron is the active ingredient used in the Sentricon bait system. It inhibits the synthesis of chitin (6) the material making up the skeleton of termites and other insects. It was first registered in 1994 as a “reduced-risk” pesticide (7). EPA’s reduced risk program waives tests for new pesticides that are thought to pose fewer hazards than existing pesticides. This means that many standard tests are lacking for hexaflumuron: medium- term (subchronic) toxicity testing, delayed neurotoxicity testing, and tests for developmental or reproductive effects (6)...

In long-term (chronic) feeding tests, hexaflumuron increased the incidence and severity of a liver cell abnormality (6). Hexaflumuron is very toxic to aquatic animals; concentrations of 0.1 parts per billion kill water fleas (6). It is persistent in soil, with a half-life (the time required for breakdown of half the amount applied) between 100 and 160 days (8).
