Ant Infestation in London: How to Get Rid of Ants
Ant infestations are common in London, especially in summer. Learn about the different ant species, prevention methods, and professional treatment options.
Common Ant Species in London
Black Garden Ant (Lasius niger) — the most common species, nests in gardens and under paving. Enters homes in search of sweet food, particularly in summer.
Pharaoh Ant (Monomorium pharaonis) — small, yellow, found in heated buildings. A serious problem in hospitals, care homes, and restaurants as they spread bacteria.
Roger's Ant — increasingly common in London, nests in wall cavities and under floors.
Signs of an Ant Infestation
- Visible ant trails, particularly in kitchens
- Small piles of earth or sand near nest entrances
- Winged ants (flying ants) — these are reproductive ants leaving to start new colonies
- Damage to wooden structures (carpenter ants, less common in London)
Why Ants Enter London Homes
Ants enter properties in search of food and water. They are particularly attracted to:
- Sweet foods and sugary spills
- Pet food left out overnight
- Crumbs and food debris
- Moisture around leaking pipes
Professional Ant Treatment
DIY ant sprays kill visible ants but rarely eliminate the colony. Professional treatment uses:
- Gel bait — worker ants carry the bait back to the colony, killing the queen
- Residual insecticide — applied to entry points and foraging trails
- Nest treatment — direct treatment of the nest where accessible
Pharaoh ant infestations require specialist treatment — standard insecticides cause the colony to split and spread.
