Question From: K. Newton - MICHIGAN
Q: Can grub-ex be used at any time? If not, when and with what do you kill grubs? Does it also kill earthworms?
The time to apply Grub-ex is from June through mid July. Reports say it does not kill earthworms. I don't have grub damage in my lawn so I do not use this or any grub killer. Best And Happy Yardening, Nancy
