The Argentine ant (Hymenoptera: Formicidae) is a major nuisance pest in urban environments. The objectives of this thesis were to expound upon existing research concerning monthly and seasonal foraging habits of the Argentine ant; further investigate the use of conventional insecticides as management options; and to assess the use of seven less-conventional products as repellents/deterrents against the Argentine ant. This research indicates that foraging activity in Barnesville, Georgia is highest from June to October; foraging activity, over 24 h, is highest during temperatures ranging from 20-30°C; continued use of conventional insecticides, namely fipronil, bifenthrin, and indoxacarb, against Argentine ants remains a viable strategy to reduce foraging activity around urban structures; and a few of the less-conventional products that are evaluated herein, namely peppermint oil, fresh rosemary, fresh spearmint, and Argentine ant trail pheromone, demonstrate repellency/deterrency to the Argentine ant in field and laboratory settings.
