A total of 12 neighborhood consisting of 12-20 houses each in Kisler Airbase, Biloxi, MS were selected based on Formosan subterranean termite alate captures on sticky traps. The experimental area within each neighborhood was aproximately 2 hectars in size. Six neighborhoods were treated using an a-cellulose baised bait formulation with 250 ppm of diflubenzuron. The rest of the neighborhoods were not treated and were used as controls. The baits were applied in Quarterra (ENSYSTEX) type undergrown stations. The stations were installed in all neighborhoods in parallel lines close to the houses spaced 5 m apart. A total of 156 stations were installed in each neighborhood. Stations were monitored monthly for termite activity between February 2000 and October 2002. In the treated neighborhoods active stations were provided with a bag of 150 g of diflubenzuron bait. Stations in the control neighborhoods were only monitored for termite activity. In addition, 1/5 of the stations in the treated neighborhoods were designated as independent monitors and were not baited even when active. At the end of the study a total of 395 stations had been visited in the control and 356 in the treated neighborhoods. Only 71 (17% of visited)stations in treated neighborhoods remained active, while 185 (46.8% of visited) stations were active in the control neighborhoods. This difference was statistically significant.
