We're sorry to read about your disappointment with the coverage of our Scotts Grubex1 Season Long Grub Control and appreciate your feedback.
We have not changed the formula or bag size of this product. If using a rotary spreader each pass should be about 5 feet apart, if your passes were closer together, you would be applying too much product. Pulling the spreader backwards will also apply too much product. When applying, you should be walking a good pace, approximately 20 feet in 5 seconds. If walking more slowly, it puts down more Scotts Grubex1 Season Long Grub Control in the same area.
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 877-220-3089 if we can further assist.
