Thank you for taking the time to send a review. We're sorry to read about your disappointment with Scotts Grubex1and appreciate your feedback. Grubex is not effective on mature grubs. Larger (mature) grubs are harder to control and resistant to most controls on the market. This product needs to be applied as a preventative in spring or early summer (prior to 4th of July) before damage is present, once damage is noticed it is too late. Also, the smaller the grub, the easier it is to control with an effective grub control product. Since timing is so critical, we recommend that you contact your County Extension Agent for the timing of grub hatch in your area. If the thatch is more than ½ inch thick, and a dense, compacted layer is present, your chances of grub control are rather slim. Control products get trapped in dense thatch layers. We want you to be confident in our products. For this reason, we offer a product guarantee to our consumers. At your earliest convenience, please reach out to us at 888-270-3714 if we can further assist.
