When Can I Put Down Grub Control?
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.
What Material Should I Use for Grub Control?
For the past decade or so, there remain a few consistently well-performing materials used for grub control. Some of our lawn care programs have included preventative grub control treatments of Merit ® (imidacloprid), Allectus ® (combination of imidacloprid and bifenthrin), or Acelepryn ® (cholrantraniliprole), which have been the industry standard materials to prevent grubs from damaging lawns. There area also a few other materials that can be used, but our experience has shown that we will stick with the tried and true for years to come.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.
