Appearance
![Image of Garden Ant [Lasius niger] | Ehrlich Pest Control](/images/image_141821.jpg)
- Workers 3/16" long.
- Queens 5/8" long.
- Dark brown–black in colour.
- 1 small segment at waist point (pedicel).
- No sting present.
Lifecycle
- Queens overwinter in soil. Eggs are laid in late spring. Larvae hatch 3–4 weeks later.
- Larvae feed on secretions from the queen's salivary glands until the first worker ants emerge.
- Worker ants continue with larval care, nest building and food foraging.
- Fertile males are produced later in the season.
Habits
- Foraging worker ants follow well–defined trails around food sources. Sweet foods are preferred but high protein foods will also be taken.
- Swarming characteristics – mating between queens and fertile males takes place on the wing mid to late summer. Males perish after mating.
- Nest locations – often outdoors in soil and below paving slabs on the sunny side of buildings. Nest locations can be identified by the presence of finely powdered soil around nest exit holes.
