Many thanks for the replies.
I am loath to kill them per se, as last year I had four dragon flies in the garden and you could clearly hear them feeding on the flying ants, plus the various birds that visit the garden can be seen picking at the nests. Its just that as the ant nest appear they make a mess of the grass that they push up through, perhaps I could encourage them to build the nests in the boarders of the garden?? any ideas??
tks
