(Length: 1/10″ – 1/8″) Introduced from Asia, this medium black to brownish-black ant species is quickly becoming one of the most persistent and invasive ant species in Florida. Its name comes from the fact that its feet are a yellowish-white color. This pest has huge colonies with nests scattered throughout the home and yard, and are extremely difficult to get rid of. They are often found foraging in trails along branches and trunks of trees and shrubs. They are strongly attracted to sweet foods and also eat dead insects and other types of protein.
