Grub Ex worked like a charm. It was applied using a Rotary Spreader in late summer. There were no signs of larvae mounds the following Spring.

Grub Ex was applied to my large yard (approximately 15,000 sq.ft. It was my first time using Grub Ex. We had just purchased the house in July 2013 aand prior to settlement a large number of mounds were noticeable in the front yard. This was a result of Japanese Beetles larvae hatching and burrowing through the grass. Rose bushes, ornamental cherry trees and red maple trees seem to attract the beetles. Being a novice, I purchased and applied Grub Ex in the late summer 2013. This Spring 2014, I didn't have any burrows in the lawn but did have Japanese Beetles in the ornamental cherry trees, red maple tree, and on the rose bushes. Beetle bags didn't put a dent in the problem. I purchased Neem Oil and mixed it with water. I applied it to the problem plants and the Beetles have not returned. If Scott's could make a Neem Oil product I would definitely buy it. A very satisfied Scott's customer.

Grubex

At a considerable cost for the past three years I have used over 200.00 each year for Grubex. Each year I have grubs. I have a half-acre and the treatment is more than adequate and it simply doesn't work. I simply raked the areas were the dead grass spots are and each time I find grubs have eaten the roots away.

Did not effect the grubs

I put the product down as directed. I paid considerably more because I have trusted Scotts products in the past for all my lawn care. I was, to say the least, highly disappointed. After putting it down I ran the irrigation system for 10 mins per zone and then we received a light shower overnight. After a week I still had grubs. I then purchased a bag a of Spectricide (less than half the cost) and the next day my yard was full of dead above the ground grubs.

Didn’t touch my grubs

Following the direction on the package to treat the area, weeks later I still have grubs. Maybe this product is not designed to kill Utah grubs? I spent a bit more as I trust Scott products, but this one is not the one for me. Now I am replacing 50 square feet of turf. Pulling the existing turf by hand only to find grubs thriving in the treated areas. Extremely disappointed!

We are sorry to hear that your Scott's GrubEx did not perform as expected. This product is meant to be applied before grubs hatch, in order to control them while they are very young. Once grubs mature, there are very few, if any, insect controls that will control mature grubs. Please contact us at http://tinyurl.com/mds8zo5 if you have an interest in discussing this further.

Gets those nasty little grubs!

I had so many grubs in my flower beds in recent years that I had to try this product. It did an amazing job of getting rid of those nasty little buggers! I don’t think I saw one grub last year. We will be using this again this year. It’s a great product!

This was a great purchase.

[This review was collected as part of a promotion.] This was a great purchase for me. The product worked as promised, and it was much faster than expected. I have no complaints whatsoever and I would definitely recommend this product . The instructions were clear and concise. My only regret is that I did not try this product years ago.

Does not work at all (I tried multiple times)

This product simply does not prevent grubs. I've tried two years in a row and applied exactly as directed. Each July I have lawn damage and the cause is obvious. White grubs everywhere.

Grubex

I used this product for the first time this year at the beginning of the season. There is such a noticeable difference in my lawn - it's a miracle. I also used Scott's lawn feed. Can't believe the difference. So happy to finally have a nice lawn!

Why is Grub Killer Plus 24 hour

Why does Scotts call this product grub killer? applied this product to new lawn few days ago, late October. Product drove grubs to the surface ( gross site ) but days later the grubs are still crawling around. when does the killing start?

Thank you for your feedback. We are sorry to hear of your experience with Scotts Grubex1 Season Long Grub Killer 10M. This is a good product and is labeled for the control of grubs for approximately 4 months if applied at the appropriate time in your area. Timing is an important factor as mature grubs require a much larger amount of insecticide to control than grubs that are newly hatched. Scotts Grubex1 Season Long Grub Killer 10M is meant to control the younger newly hatched grubs thus preventing lawn damage. Therefore we recommend applying Scotts Grubex1 Season Long Grub Killer 10M from May through the end of June. If there is anything we can do to help you have a 5-star experience, please contact our Consumer Services team at 888-270-3714 for assistance.
