Living in Southeast Texas, ants are a year round nuisance. They are one of the most successful groups of insects. Ants are social insects that live in colonies which are mostly located in the ground, but may forage into structures for shelter, food and moisture. Ants feed on most all kinds of food products but primarily feed on sweets and protein containing items. Approximate 700 species of ants live in the United States and Canada. Of these only 25 species readily infest structures. Ants have complete metamorphosis : egg, larva, pupa, and adult stages. Ant colonies contain 3 distinct castes - workers, queens and males. Accurate identification of certain species of ant is necessary in determining correct control method.
