Moisture Ants in Jacksonville FL

Moisture ants get their name from their habit of nesting in high-moisture areas. Wood invaders, moisture ant colonies are generally located in decayed logs and stumps, but may also occur in soil. They feed on sweet materials and also tend aphids for their honeydew. These ants are not a primary structural pest, but they can speed the deterioration of wood. They also become a nuisance as they enter homes in search of food. Frequently associated with decayed and rotting wood, moisture ants can invade homes and structures.

Moisture Ant Habitat

Moisture ants construct galleries in rotting wood within which they feed. As their name implies, moisture ants prefer to live in damp and humid environments. Outside, these ants like to inhabit wet areas such as soil or rotting wood. They will nest in moist ground, generally in a crawl space, and will construct elaborate mud tubes that resemble a sea sponge between the ground and wood. Sometimes their structures are mistaken for subterranean termite tubes. Inside homes, these ants are often discovered behind walls, especially during renovations.
