What's the first sign of ants in a UK home?

A single-file trail along a worktop or skirting — usually appearing overnight in late spring — is the everyday opener.

When are ants most active during the day?

Garden ants daytime; pharaoh ants 24/7 indoors. Ants make no audible noise in a domestic setting.

How do I know it's ants and not something else?

Ants are most often mistaken for termites or wasps. If you can trace the trail back to a single entry point (a gap in a slab, a cable hole), gel baiting will clear it. If trails appear from multiple points, the colony has budded and a survey is needed.

When does a ants sighting become urgent?

Tiny yellow ants in a shared building, or trails appearing in winter — both point to pharaoh ants, which need professional treatment.

Where do ants usually nest or hide?

Under paving and inside cavity walls. Garden ants nest under patio slabs, path edges and at the base of south-facing walls. Pharaoh ants nest inside cavity walls and pipework boxing.

Can I treat ants myself?

Killing foragers triggers budding and several new colonies — use baits, not sprays. The break-even point usually arrives at the second piece of evidence — a single specialist visit at £50 typically beats three rounds of shop-bought product.
