Ants in a flat are less common than in a house — there is usually no garden and fewer ground-level routes. When it does happen, the route is generally traceable to one specific gap or a food source below.
| Route | How common |
|---|---|
| A nest in soil against the building, at ground level | Common in a ground-floor flat |
| Up a cavity or service riser from ground level | Common |
| Balcony planters and pots | Common on upper floors |
| Through a gap around pipework or ducting | Common |
| From a commercial unit below | Worth checking |
| A nest inside the structure — a warm void | Less common, but persistent |
| Carried in on plants or shopping | Occasional |

No garden in most cases, fewer ground-level entry points, and an upper floor is genuinely harder for ants to reach.
Balcony planters most often — a pot is a perfectly good nest site. Check underneath them before booking anything.
A commercial kitchen below is a substantial food source and the business has its own pest control duties. Tell us — it changes where we look.
Follow the trail to the entry point, check balcony pots, clean the whole route with detergent, remove the food source, and seal the gap.
