Black House Ant

Ochetellus glaber

Characteristics

The Black House ant is a small, intense black, shiny ant measuring about 2.5mm to 3mm. They are one of the most common pests encountered by homeowners in Australia. When crushed, they emit a distinctive, pungent odour. They are highly persistent foragers and will trail along "scent paths" for long distances to reach a food source.

Habitat

These ants are highly adaptable. Outdoors, they nest under bark or in garden beds. Indoors, they are notorious for nesting in wall cavities, ceiling voids, and even inside electrical appliances or around window frames. They are drawn to kitchens and bathrooms in search of moisture and food.

Lifecycle

Colonies are typically moderate in size and contain multiple queens. They are prolific breeders, and a single infestation can quickly spread throughout a property if not managed early.
