Japanese beetles have now laid their eggs in the lawn and very soon will be hatching. These grub worms can create havoc and potential destruction of your lawn. If your lawn seems to be thinning or yellowing even though it's getting water, pull on your turf. If it comes up easily, you probably have a grub issue. Apply Grub Beater for the quickest resolution. If you want a longer term solution, try Milky Spore. It won't resolve the problem now but will provide protection for up to ten years. If you have additional questions, a Blooms Bros professional can help you choose the right product for your lawn.
