Ants belong to the family Formicidae, along with bees and wasps, to the order Hymenoptera, which includes eusocial insects. When they get into your home or when you’re having a picnic, ants can be annoying, but they do help the environment in other ways. A majority of ants are found in a home nest outdoors and enter a home to search for food. Each ant species has its own food habits. Ants are closely related to bees and wasps, both of which have a narrow waist segmenting their bodies.
