Rover Ant

Very small (1.5–2 mm), color ranges from pale honey to dark chocolate brown. Diagnostic features per Texas A&M: 9-segmented antennae with no club (most household ants have 10–12), single hidden petiole node, and dense, fine body pubescence. Workers move slowly compared with crazy ants. Easily mis-keyed as 'small dark ant' without magnification.

Colonies are surprisingly small for a tramp ant, often a single queen and a few hundred to a few thousand workers, but the species compensates by colonizing nearly any small protected harborage: a potted plant, a wall void around a leaky shower, a stack of cardboard, an irrigation valve box. Strongly associated with moisture and fungal decay.

Persistent indoor nuisance, workers trail in bathrooms, kitchens, and around HVAC condensate lines. Not a stinger, not a structural pest, but reinvasion from outdoor mulch and landscape beds is constant. In the Gulf South, rover ant calls have surpassed odorous house ant calls in some markets.

Combine sweet liquid bait at every interior trail with a non-repellent perimeter band and aggressive moisture correction. Because colonies are small and scattered, treat each separately rather than expecting a single bait placement to collapse the population.
