Each year we seem to be getting an increasing problem with little brown lawn

From a distance it looks like we've got mole hills but on closer inspection
they're definitely ants.

It has all started to get quite ugly and a problem

Anyone got any tips?

When mowing the lawn a couple of weekends ago, I found I'd taken
the top off a 2m" ant hill. Millions of the things were rushing
around gathering up their eggs and taking them lower under ground.
A couple of metres away, the same had happened to a smaller red ant
hill. I looked out half an hour later, and the garden birds had
found it. It was so funny -- they were trying to eat the ant eggs
whilst being bitten on their feet by the ants. There were about 20
birds there all hopping up and down like the ground was too hot to
stand on, but presumably the delicacy was worth the pain.

A couple of years ago I killed the small lawn out the front. When I
lifted the concrete paver that bridged the border I found an ants nest
underneath. Being a nice sort I covered it over with more sand which
linked to the first of the round pavers I was laying as a stepping stone
path out across the new garden. Landscape fabric went down with bark
chips on top. Now every time I have cause to lift the fabric I find ants
apparently taking advantage of the covered highway away from the birds.
There is now an ant nest in the sand under each of those pavers, a bit
like the Polynesians colonising the Pacific islands ;-)
