Ant trails along the paving or up the side of the house are usually just the visible bit of a much bigger nest, and a contact spray alone won't stop them coming back. These granules kill on contact and then sit down a residual barrier that keeps working for weeks.
Scatter 250g per 10 square metres for a heavy infestation or 75g per 10 square metres for a lighter one, covering Argentine, black house and coastal brown ants, the usual backyard offenders. Simple to spread by hand across the problem area.
A barrier that actually holds, not just a quick knockdown.
