• Correct identification crucial to select the appropraite control technique
  • Location of the nest(s) - determine if the ants are coming from outside or under the structure.
  • Ants tend to trail along in corners or edges such as baseboards, edges of countertops and splash boards, tops of wires and pipes in walls. 
  • Exclusion - seal possible routes of entry such as any openings around pipe and utility line entrances, window and door frames, wall-mounted AC units, light fixtures, fascia boards, etc.
  • Perimeter treatment - treatment zones are typically effective in reducing or preventing inside entry. Treatment of infested trees may be required. 
  • Reduction of honeydew sources. If they feed on honedew produced by aphids, mealybugs, and/or scale insects, the plants near the structure that harbor these insects should be treated also
  • Interior pesticide application - Application directly onto foraging trails of ants inside is often required. This will usually give results in a few days at most. 
  • Baiting - can be the most effective or only way to control some ant species
  • Other - Remove ant food such as garbage, removal of plants attractive to ants
  • Change landscaping to discourage ants; Trim trees and shrubs
  • Reduce moisture sources, keep gutters clean, eliminate sources of condensation
  • Replace outside hollow-core doors with solid doors.


  • Life cycle: egg, lava, pupa, and adult
  • 3 distinct castes: workers, queens, and males
  • Easily recognized by their elobowed antennae and node-like structures that form their slender waists
  • Three body regions (head, thorax, and addomen) defined by distinct constrictions.
  • Workers are females, never with wings
  • Queens, typically the largest in the colony, establish new colonies and lay eggs. They can lay fertile eggs for their lifetime 
  • A colony may contain many functional females or queens, but only one founding queen. 
  • Unmated females have wings and mated females remove them
  • The male is usually between the worker and the queen in size and his only function is to inseminate the queen
  • Males die shortly after mating, usually within 2 weeks
  • Adult ants, workers and reproductives, do not eat solid food. They eat liquids which may be stored
