How to identify it

Small (2–3 mm), light to dark brown, moving in wide, well-defined trails. They have a single node between the thorax and abdomen and lack the musty odor of odorous house ants.

Where it hides

Moist soil, mulch, under pavers and debris, and inside wall voids near moisture. Thrive year-round in Florida's climate.

Signs you have them
  • Wide, steady trails of small brown ants along sidewalks, walls and counters
  • Trails moving into kitchens following any food or water source
  • Supercolonies that seem to have no single nest — just endless workers
Why it matters

Argentine ants don't sting or cause structural damage, but their supercolonies (millions of workers, many queens) make them extremely difficult to eliminate with off-the-shelf products. They overwhelm kitchens and contaminate food.

How Rhino treats it

Rhino uses slow-acting non-repellent baits that workers share throughout the supercolony, combined with exterior barrier treatment to cut off entry points.
