What to look for
These signs can help inform an inspection. They are not a confirmed identification on their own.
- Trails of ants leading from outside into the kitchen or living areas
- Small piles of dirt or soil near ant entry points
- Ants in or around food storage areas
- Flying ants during summer months
- In commercial premises, ants in food preparation or patient areas
What to do next
- Record where and when activity appears, and photograph visible signs from a safe distance.
- Reduce accessible food and water, and inspect storage or waste areas without disturbing nests or contaminated material.
- Ask a qualified pest professional to confirm the species and inspect access routes.
- Request a written treatment plan, including any preparation, return visits and prevention work.
Questions for a treatment quote
Ask which method is suitable for the identified species and your property. Explain whether children, pets, food preparation or vulnerable occupants need special consideration. Get re-entry and cleaning instructions directly from the appointed professional.
A quote should separate inspection, treatment, follow-up and proofing. Avoid assuming one visit or an advertised guarantee covers every recurrence.
Local context
In a shared London building, activity may involve adjoining flats, communal waste stores or service routes. Give the managing agent a dated record and agree access arrangements before the survey.
