We already have a list of lawn care customers who want their lawn treated for grub control. There are two times a year that application for grubs is applied. A spring application usually is applied to areas of your lawn where you had not previously seen grubs. These applications are applied as grubs emerge from their winter hiberantion and begin eating organic matter like grass roots. The more common application is applied about mid July or late July. This is when the grubs are most active and begin to pupate (change into their adult form) turning to beetles. Grubs are easy to spot. Just dig down six to eight inches in any part of your lawn and you will likley notice a white C-shaped worm about 1/2″ – 3/4″ long. The more grubs per handful of soil the more damage they will cause to your lawn. This mid to late July application of preventive insecticide will keep grubs from over wintering in your soil.
