An experimental insect growth regulator (IGR) termite bait system was placed with the objective of eliminating a persistent aerial termite colony active in the top three floors of a six-story, 100-unit apartment building. Following delineation of their foraging territory, bait matrix containing the active ingredient lufenuron was placed in contact with actively foraging termites within five infested apartments. Termite feeding activity was evaluated monthly. The infestation emanated from one colony of Reticulitermes flavipes. Bait was replaced as needed until all foraging activity ceased and no subsequent swarming occurred. No recurrence of swarming or foraging activity has been observed for seven years following cessation of termite activity within bait stations.
