Is there a plague of ants going on?

All the pavements, roads and car parks I've walked across today have lots of little sandy eruptions around paving stones and edges of tarmac where ants are appearing. Is it everywhere or just here in Suffolk?

And any ideas why - warm weather, an abundance of sweet sap and aphids for them to farm, or perhaps they're about to turn into flying ants? Think that's usually June/July though.
