One of the most common insects that invade the household is the Garden Ant or Black Ant. The ant is an active insect and sometimes nests inside in nooks and crannies.

As its name implies, this is a black ant although more accurately it is of a blackish-brown colour. It varies in size from 3 to 5mm (1/10th to 2/10ths).

The common black ant lives out of doors where it can be found nesting in cracks in lawns, around and under stones, at the roots of many plants on which black and green fly are feeding, between bricks in walls, in crazy paving and many other places. Around buildings, the nest opening many is distinguished by small piles of fine earth brought up from under the flagstones etc.
