Is It Too Late To Apply GrubEx?
If you have not applied your GrubEx yet this year and you have had a serious grub problem in previous years, I say go for it ASAP. A sign of upcoming grub problems is if you have been seeing lots of Japanese Beetles feeding on your roses and other plants or other kinds of beetles hanging around your porch light at night. The best time to apply GrubEx is late spring to early summer. You may see some reduced control with an application in late summer, however reducing your grub population this fall and next spring would be better than doing nothing. It is best not to apply to waterlogged soils. If there is no rain after spreading, don’t forget to turn on your sprinklers so your lawn will get about a quarter to a half inch of water.
