Black Garden Ants
The Black Garden Ant (Lasius niger) workers are 4-6 mm long, wingless and black or dark brown. They are usually found in large numbers, either around their nests in the soil or following each other along their scent trails across the ground and paved areas, over walls and into buildings. Worker ants can be seen foraging on the ground and in houses. The winged adults fly on certain afternoons. The black garden ant is virtually a harmless creature to the human population. They are unable to carry any diseases and do not bite. Their major aim is to eat, mate and work for their colonies which are how they can host up to ten thousand workers at a time. However, these ants tend to attract special kinds of predators. Their movements are scattered and exploratory and may also cause damage to infrastructure though at small scales. They are known to create cracks that cause water and soil leakage into gardens and homes. Black garden ants eat most of the food they can scavenge. They are not picky eaters and will eat from fruits and seeds to small insects. The ants also farm honeydew from aphids that they capture from around their chosen sites.
