Colonies of army ants are large compared to the colonies of other Formicidae. Colonies can have over 15 million workers and can transport 3000 prey (items) per hour during the raid period. [14] [20] When army ants forage, the trails that are formed can be over 20 m (66 ft) wide and over 100 m (330 ft) long. [20]

Dorylus spp. colonies also reach larger sizes than ...
For minor sting injuries, with symptoms only including pustule formations and pain, over-the-counter products are available to prevent infection. Ants should be removed by washing the area with antiseptic soap, and itchiness. It is rare for ant sting sites to become infected, so the use of antibiotic prophylaxis is not always required.
