Because there is a wide array of grub types, homeowners concerned about grub problems should consult a professional on the best course of treatment. Some products work best when grub damage is minimal. Others work only as preventive treatments and won’t kill existing grubs. Use the wrong product and you’re not only wasting money, you could potentially damage other beneficial microorganisms or insects in your soil.
“The timing (of the application) is the most critical part of it all,” Tice adds.
If you have extensive grub damage, you’ll likely need to reseed that area of the lawn.
“The parts that have already turned brown aren’t savable,” Ory says. “Those have to be torn out and reseeded. That’s why it’s pretty devastating when you do have them. They can do a lot of damage in a hurry and a lot of people don’t recognize it because it’s drought season.
