Garden ants (Lasius niger)

Appearance & Features:

Garden ants are black in colour and have segmented bodies.  The queen is usually around 15mm long and workers are much smaller at 5mm in length.


Ant nests are usually found in gardens under lawns, flower beds, paving stones etc. and the opulation per nest can be in the thousands.

Ants are social insects and opportunistic feeders that feed on meats, nuts, cheese, honey, bread crumbs, meats, grease and pet bowls.  They can easily be controlled with bait as they will "swarm" on foods that appear within their foraging range. 

Winged ants are reared during summer months and fly in swarms between July and September on warm and humid days.

When foraging they sometimes all follow a trail which can lead inside human occupied buildings.

Threats to humans:

There is no direct threat to humans from garden ants as they don't transmit disease or bite.  


Any colonies can only be eliminated by direct treatment of the nests.  Perimiter treatments can be effective in controlling where they forage using ant baits.
