Black Garden Ant
Lasius niger
- Order & Family
- Order: Hymenoptera; Family: Formicidae
- Size
- Workers are typically 3 to 5 mm in length; queens can be up to 9 mm.
Natural Habitat
Commonly found in gardens, under pavements, and inside buildings particularly in kitchens and bathrooms looking for food.
Diet & Feeding
Omnivorous; they feed on nectar, seeds, small insects, and are famously known for farming aphids to harvest 'honeydew'. Indoor foragers seek sugary and protein-rich human food scraps.
Behavior Patterns
They are social insects living in large colonies. They use pheromone trails to communicate with nestmates and are most active during the day. They undergo complete metamorphosis (egg, larva, pupa, adult).
Risks & Benefits
Generally harmless to humans as they do not possess a sting, though they can be a nuisance when infesting homes. Ecosystem benefits include soil aeration and acting as a food source for birds and spiders.
