Populations of the arboreal termite, Nasutitermes corniger , discovered in Dania Beach, Florida in 2001 were surveyed and treated for eradication, beginning in 2003. Most N. corniger nest locations were cryptic and some nests contained over 1 million termites. Field efficacy of fipronil (Termidor® SC) and imidacloprid (Premise® 2) were compared in initial treatments, and fipronil was selected for termite-active sites through 2010. In 2006, expanded survey work was discontinued. By 2010 all sites within the original survey area were termite-free. In 2011, a new population of N. corniger was discovered beyond the original 2003 infested tracts. A new (2011–2012) survey revealed a total of four areas outside the original tracts that were infested with N. corniger . No tract treated with fipronil between 2003 and 2010 showed evidence of renewed termite activity in 2011–2012. New application procedures using nest-only and fipronil dust treatments were instituted in May 2012. Live termites were still found within the 2011–2012 treatment area as of November 2013. Very slow but continued spread of N. corniger in tropical urban Florida will have economic consequences as a result of nuisance and structural damage.
