Brown patches in your lawn now, typically mean you have grubs. To be sure, peel back a section of the dead turf…look through the dirt and you might find some juicy white grubs there. If so, here is what to do…apply Bayer 24 hour grub killer with dylox. This is a systemic that is absorbed into the grass…then when the grub bites off some of the root of your grass, he dies. Grubex and Bayer Grub Control will not work now…they are typically June-July applications, while Bayer 24 hour with Dylox is April-May, August-September. Want to know why?
