Ants

Some species of ants can cause localised problems on lawns, especially in dry sunnier conditions. The Yellow-Meadow Ant (whose scientific name is Lasius flavus) can be a particular minor pest of turf surfaces. They create small to significant medium sized mounds of excavated soil which can smother grass and cause surface unevenness. The soil is best brushed up or spread around where it has been excavated, however, this can be a daily task while the ants are active over the summer period.

Scalping of lightly raised areas is a common problem, so be aware of this and slightly raise the height of cut or tilt back a little on the mower handle when going over the area to try and reduce the chance of scalping.

Consideration might be given to a light forking and drenching of the area with cold-to-air temperature water. This might flood them out and encourage them to move on to other areas, or not, but it could be worth a try.
