A field test of bait systems using Diflubenzuron, Chlorfluazuron, BioBlast, and a combination of Diflubenzuron and BioBlast in a nutritionally-based bait matrix was implemented in Poplarville, Mississippi in an area-wide basis. Six neighborhoods were chosen for this study. Three neighborhoods were treated with Diflubenzuron, one with Chlorfluazuron, one with BioBlast, and one with a combination of BioBlast and Diflubenzuron. Every property of each neighborhood was treated by installing ENSISTERX Exterra-type undergrownd stations around structures every 5 m. The stations were monitored monthly for subterranean termite activity. Active stations were treated with 150 g of bait. Bait consummed was recorded monthly by remooving empty bait bags from the stations. The cummulative number of active stations was recorded and compared with the observed number of active stations to calculate changes in the percentage of active stations over time. Significant reduction of termite activity was recorded in all the neighborhoods 18 months of treatment. The Diflubenzuron treatment showed complete suppression of termite activity in 50% of the treated properties after 24 months of treatment.
