Mymecia Spp.


Image of Bulldog Ant (Mymecia Spp.) | Ehrlich Pest Control
  • 18-20 mm
  • Tends to be red or black


  • When a Queens starts to nest she digs a small chamber to lay her eggs in. There is one Queen ant that lays all the eggs and one or only a few males that are just there to mate with the Queen
  • The ant’s life cycle passes through egg, larva, pupa and adult phases
  • Almost every ant is born female. The eggs hatch into small grubs, which grow into a particular caste (most are workers, then soldiers)
  • The Queen Bull Ant leaves the nest at night to forage and supplement the food supply for her progeny (baby bull ants)
  • The Queen may live for several years


  • Very aggressive (if a nest is disturbed, there will be a massive outpouring attack)
  • Typically nest outdoors in soil or under logs or rocks and they build quite an extensive tunnel system
  • Located mostly in bushy areas (they seldom enter buildings)
  • They can inflict a very painful sting to humans
  • The stinger does not remain in the victim, so the Bull Ant can sting repeatedly
  • They feed on other insects and things such as honeydew from scale insects or plant nectar
  • Each ant belongs to a specific caste and has a specific job to do (there are worker ants, soldier ants, the Queen and the Male – who mates with the Queen)
