Crazy ants often nest in soil of potted tropical plants and do not survive outdoors in colder climates.

Pavement ants are often found under sidewalks, driveways and building foundations. Look for mounds of displaced soil on pavement cracks or walls. During the winter, pavement ants may nest inside structures near a heat source.

Carpenter ants nest in wood and are often associated with moisture problems. In structures, they are often found where water has leaked and soaked the surrounding wood, around plumbing, and under windows.
