They prey on insects, lizards, birds and small mammals, and are often found hunting for insects in the company of baboon. They love birds' eggs and crack them by pitching them backwards through their hind legs against a rock or stone (the Dwarf Mongoose has a similar habit). Banded mongoose are very courageous creatures and a troop will attack a poisonous snake. When they are cornered by a predator, they spit like a cat and put up a defence. When they are at home, the female dominates the male.
Banded Mongoose live in troops averaging 30 individuals, and sometimes large colonies of up to 75. They can be heard from a distance as they march across their territory foraging for food: the rustling of grass, scratching of earth, and constant twittering help to locate them.
