Life Cycle and Common Characteristics

  • A mature queen lays hundreds of eggs each day.
    • Eggs hatch to grub-like larvae in 7-10 days and reach a pupal stage in the next 1-2 weeks.
    • Pupae look like a curled adult and cannot move and in 1-2 weeks they acquire reddish brown pigmentation and turn into an adult.
    • Multiple queen colonies have closer and more numerous mounds per acre of land.
    • Worker ant activities are found in gardens with nests occurring both in lawns and in shaded patches of exposed soil beneath trees and ornamental plants.
    • Peak worker activity coincides with the cooler hours of morning and afternoon.
    • The queen in multiple queen colonies produces more eggs as compared to a single queen.
    • When a mound is disturbed, ants emerge aggressively to bite and sting the intruder.
    • After heavy rain, the colony may move to higher ground or inside homes to take refuge from saturated soil.
    • The tropical fire ant does not build mounds, instead, dirt is spread widely around the nest entrance.
