The velvety tree ant, Limetopum occidentale Emery, is commonly found in urban areas throughout the western U.S. and has been reported damaging structures. Foragers prefer sucrose, glucose, and honey sucanat solutions. Solid protein baits containing anchovy also were retrieved by workers. In the early summer, foragers were active both day and night. In the late summer when daytime temperatures exceeded 35°C, workers only foraged at night. Even though workers are polymorphic, they all consumed about 0.25 mg of a 25% sucrose solution and thus providing a mechanism of determining foraging activity by determining sugar water removal from monitoring stations. Liquid bait bases containing 25% sucrose would be effective if suitable toxicants can be identified.
