Garden Ants
What do they look like?
- Garden ants are shiny black and approximately 2-3mm in length.

What are their habits?
- Common in houses, buildings and gardens during the summer months, garden ants form distinctive trails in lines often extending indoors from outside as they forage for food away from the nest
- Nests are often close to buildings and associated with warm sandy soil under paving stones, patios and conservatories. Occasionally nests are found in the base of walls or in the under-floor voids of buildings
- Garden ants have a single queen colony and the life of a nest and its queen can last several years
- Foraging parties bring back a wide variety of foodstuffs from sweet sugary secretions taken from aphids and black-fly to seeds and insects.
How do they breed?
- Fertilised queen garden ants dig into the soil creating a cell in which eggs are laid
- After 3-4 weeks eggs hatch into grubs which are then nourished with rich salivary secretions from the queen
- After 3 weeks grubs pupate and 2 weeks later worker ants emerge and set about feeding the queen and the developing grubs within the nest
- Collectively they work for the good of the nest defending the queen and moving larvae if they have to
- On hot days in late summer, small winged males emerge and mate with larger winged queens as they emerge and disperse from the nest. After mating males quickly die and queens shed their wings in search of a suitable nest site
- Swarming behaviour occurs when ant activity is at its peak.
Danger Signs
- Garden ants - lines of foraging ants moving inside or into buildings from outside
- Entry points may be indicated by signs of excavation or freshly dug earth around door frames or wall-floor junctions
- Winged ant swarms inside or outside of the building.
Problems and Business Consequences
- Whilst not a specific risk to public health, foraging ants in kitchens and office areas can represent a nuisance. Indoors they would be particularly attracted to sweet residues or food waste and can gather in numbers
- Unlike exotic tropical ants which can occur in large buildings and hospitals, garden ants are not known to carry any specific pathogens or diseases.
Steps to Take Yourself
- Ensure good standards of hygiene and housekeeping, especially in food handling and waste storage areas
- Observe entry points and, if holes are present along the base of door frame or wall floor junctions –especially in kitchens or conservatories, seal the holes with silicon sealant, mortar or cement to reduce the risk of ant access
- Note the areas where ant activity is found
- Promptly remove food waste or spillages and cover foodstuffs.
