PAVEMENT ANTS

INTRODUCTION: This ant gets its name from commonly locating its nest in or under cracks in pavement. The early colonist introduced pavement ants from Europe.

RECOGNITION: Workers monomorphic (one worker size), about 1/16-1/8” long: queens about 3/8” long. Body light brown to black with paler legs and antennae.

HABITS: Inside, Pavement ants will nest in walls, insulation, floors, and near heat sources during winter. Outside, these ants nest under flat stones, under sidewalks, along curbing, under concrete slabs. These ants feed on almost anything, including insects, meats, seeds and sweets, but they prefer meats and greases.  They forage in trails, and for distances of up to 30 feet. Although not aggressive, workers can bite and sting.

BIOLOGY: Colonies are moderately large, averaging 3,000-4,000 ants and several queens. Developmental time varies from 36 to 63 days. Winged reproductive appears outside primarily in June and July, but may emerge anytime inside including during the winter months.
