Preventative grub control is done June through August.  Grubs can be a particularly tough problem.  Grubs are small, off-white  insects. Unlike surface feeding insects which feed on the grass blades, grubs feed on the roots of the grass plants.  They can destroy your lawn in no time at all.  Fortunately there's a method of control that controls grubs before they destroy your lawn. There is a  product that allows me to treat your lawn for grubs on a preventative basis.  I will treat your lawn before the grubs are present.  This product sets up a protective barrier which will kill all the grubs as they hatch.  It's the latest grub control technology available.
