Black garden ants

Black garden ants also known as common garden ant (Lasius niger)

Black garden ants

The Black garden ant is normally found in damp soil conditions under slabs or railways sleepers. The average colony of ants is around 15-20 thousand. During hot months these ants make their way into our homes to search for rich pickings of available foodstuffs. They are known to devour other insects and collect nectar from flowers.

The overwintering queens begin to lay eggs in the spring, once they hatch the queen will feed them from secretions that come from her salivary glands. Once they pupate, they will form the well-known ant eggs that we see when we lift a slab in our garden. The nests can be as deep as 6-8 feet in the ground.

In the summer as the temperatures get really hot and humid the males and females from the nests fly. Whilst flying they mate, after this process the males die off and the females lose their wings. The females then overwinter and the whole process begins again.
