Ant trails that return within days of cleaning, mounds or holes along paving and garden beds, or ants entering through the same gap each time suggest an established colony. A professional assessment can identify the species and trace the activity back towards its source.

Cleaning removes the trail but not the colony. Ants usually return if food, moisture or an entry point remains, or if the nest is still active nearby. Treating the source and reducing what attracts them gives a better chance of lasting improvement, though returns cannot be ruled out.

Ants can contaminate food and are best dealt with promptly. Keep food covered or sealed, wipe up spills and avoid handling food that ants have reached. If the activity continues, arrange an assessment so the source can be found and a suitable treatment chosen.

Surface sprays usually only affect the ants you can see and can scatter a colony, creating new trails. If you do use anything, follow the label carefully and keep children and pets away. For repeated activity, a professional assessment is usually the better step.

It starts with an inspection inside and outside to trace trails and find likely nest areas. We then discuss suitable options, carry out the agreed treatment with appropriate safety precautions and explain any areas to avoid afterwards. The exact approach depends on the species, the location and access.

It varies. Timing depends on the species, the size of the colony, where it nests and the treatment used. You may still see ants for a period afterwards. We cannot promise a fixed timeframe, but we will explain what to expect for your situation and what to do if activity continues.

Arrange it when ant trails keep returning, you find mounds or holes along paving or garden beds, or ants are reaching food areas despite regular cleaning. Acting early is wise, as colonies can grow, and it is worth calling promptly if activity is close to food preparation areas.
