Remedial Baiting with Hexaflumuron in Above-Ground Stations To Control Structure-Infesting Populations of the Formosan Subterranean Termite (Isoptera: Rhinotermitidae)

Above-ground bait stations composed of reclosable plastic bags containing bait matrices impregnated with hexaflumuron were placed directly over active infestations of the Formosan subterranean termite, Coptotermes formosanus Shiraki. Of the 5 colonies tested, 2 each of aerial colonies and ground-based colonies were eliminated. The population of 1 ground-based colony was reduced from >2,000,000 to 155,000 foragers. The results demonstrated the feasibility of introducing baits into active areas of infestation of subterranean termites. In addition to the in-ground baiting system, the above-ground bait station may offer another option for bait delivery to affect the structure-infesting populations of subterranean termites.
