Black Ants are a common pest around Perth & Ellenbrook

Black ants (ochetellus glaber) are found in suburban and rural areas across their native Australia. When in the natural habitat, they usually nest in sand, under rocks, in rotting logs, or under the bark of trees. But almost any crevice or cranny will do, even the hollow stems of plants.
In the wild they perform a useful function, eating the eggs, larvae, and pupae of other insects, along with small adult insects. They also eat small worms, seeds and other plant material.

Worker Black Ants

Worker ants are active by day and night. They are often discovered tracing convoy lines across walls, benches and floors. These trails can stretch long distances.
It’s not uncommon to find black ants in your laundry, pantry, kitchen or bathroom.
Adults grow up to 3mm in length. Their colour ranges from glossy black to dark chocolate brown. When crushed, they emit a strong odour. \
Thankfully, like all other ants of this group, they lack a sting. However, they can bite.
