What is today’s date? There are two main types of grub control treatments, preventative grub control and corrective grub control. If you are asking this question in spring or early summer, you’ll most likely need to direct your attention to the preventative grub control materials. These materials are applied well before grubs hatch in late summer and can provide several months of control as it remains ready to kill grubs after they first hatch and start to feed. If you are asking this question later in the summer or fall when you have found grubs in your lawn, you will need a curative control. This material provides good control when watered into turf with feeding grubs and has very little residual activity. It’s basically a quick-kill product.
If a corrective grub control is needed after grubs have been found feeding on a lawn, we have most frequently used Dylox ® (Trichlorfon, Dimethyl) to provide a quick method to kill grubs in lawns.
Whichever material you go with, the material will need to be watered in within a specific period of time so that it can get under the turf to where grubs feed. Consult with the material’s label for these recommendations.
