Ants

Formicidae · Ants

Ants are social insects that live in colonies; most household species nest outdoors and send workers inside looking for food, water or shelter from hot, dry or flooded conditions. A trail in the kitchen usually leads back to an entry crack and a nest nearby. Most are nuisances, though a few, such as fire ants, can sting.

Look for: Wingless workers with a pinched waist and elbowed antennae, often marching in a single-file trail toward sweets or grease.
