Rated 1 out of 5 by from Two applications and still have problems I applied the product at the suggested rate and watered it in. We went on vacation and when we returned the lawn had holes from grub-seeking varmints all over again. I called the Master Gardener's hotline and they to recommended to reapply, which I did again carefully following the instructions. The horrendous holes never stopped, not in 24 hours and not in 48 hours. They scoop up the top layer of grass to get at the grubs eating the roots. I have my receipts - how do I get my money back so I can get something else?

Rated 5 out of 5 by from Effective Grub killer I purchased this product early summer. after the first application, I visibly saw dead grubs on top of grass, and few weeks later, the dead grass recovered. I will use it every season.

Rated 5 out of 5 by from Grub Killer Plus I have used Bayer Grub Killer for a a few years and I am pleased to say that I no longer see the effects of grubs in my lawn. This product is easy to use and there is no doubt of it's effectiveness. I will continue to use this product so that I will not have to deal with grubs anymore. Thank you , Caster Salemi

Rated 1 out of 5 by from Poor Product Bought this a month ago and followed the instructions on how much to put on my lawn then I watered it into the grass. As of today I have 4x's the amount of grubs then I did a month ago. I actually go out every night with a flashlight to see how my grub population has grown.
