August 17th-I have 6 lawns that "appear" to have grub damage. Lawn in sunny areas have some dead spots, the dead grass spots pulls off the soil easily, some of the good grass rolls back a little with soil attached, however I cannot find any grubs-I checked good grass, dead grass areas, but no grubs. I fertilized these lawns with Mach II in June. It is not a fungus, only appears in sunny areas. What other insect should I be looking for. I would like to know what I'm dealing with before I just start applying Dylox 6.2.
