I have grubs in my lawn and flower beds. I know how to treat my lawn but I’m not sure what to do about the flower beds.

White grubs are the larvae of various scarab (or chafer) beetles, including Japanese beetles, June, and May beetles. The larvae overwinter in the soil and pupate in early spring, with adults emerging in late spring to early summer. Michigan had a long, cool spring. This stalled the emergence of the adult beetles, which are currently devouring the landscape. The adult beetles are only susceptible to repeat insecticide applications. If you find a small infestation, hand-picking and dropping them into soapy water will suffice. However, adults are present through the entire growing season. It is important to be vigilant so adult beetles do not lay more eggs in the soil. The eggs are invulnerable. The grub larvae are susceptible to several kinds of granular insecticide sold specifically for lawn treatments for grub control. You can work this granular formulation into your flower beds as well. Remember, grubs feast on roots, which means perennials and ornamental shrubs are also on the menu, along with your lawn. As you work the soil in your flower beds, you can destroy grubs and pupas as you find them. That’s one less procreating eating machine in the landscape.
