I had heard that coating your lawn with a good coating of lime will help get rid of the grubs. Is that true? I also have a lot of ants, our soil is very sandy. Will lime help with them also?

Grubs cannot survive in sweet soil. Using lime in early spring will help keep grubs away; however, this will not effectively eliminate them. Ants do not like lime and will normally move away from the area if it is applied to the lawn. It is said that an application of lime over your lawn will work for the entire year, though this has not been proven.
