- Ants are social insects where the queen lays eggs
- Workers find food, defend and maintain the nest
- Workers will share the food throughout the entire colony
- This process is called trophollaxis
- Since ants are social insects
- The best measure to manage them is through baiting
- Where the workers will then share the baits to the rest of the colony
- Pesticides spraying against ants will create repellence to the ants
