Have white grubs in st augustine grass. Cut out a 12'×12' area and counted 7 grubs. I did use grubEx the first of June.
You can use 0.6 fluid oz Prime Source Imidacloprid 2F Select T/I per gallon of water. Prime Source Imidacloprid 2F Select T/I is labeled for grubs but more for preventative treatments. For best results, soil applications should be done in mid-June to mid-July prior to grub egg hatch. Depending on your region, grub egg hatch is typically from late July through late August.
For actively feeding grubs, Dylox 6.2 Granules is recommended for immediate grub control within 24 hours of the application being watered in. Mature Grubs may require a second application.
Please review our article on How to Get Rid of Grubs for more information.
