I had grubs last year and I have used a different product a few year ago. I redid the bad spots and seeded in the fall and the lawn looked great this year until August. In August I noticed brown spots and again found grubs.

Rated 1.0 out of 5.0 by Anthony Didn't do well this year
Purchased and applied July 12th. September 10th I found extensive damage being done. I applied at the correct rate, and watered in. I check for damage every weekend, to try and catch issues early but was out of town for a long Labor Day weekend. I had to purchase a 24hr emergency grub killing product to stop the damage

For the most part this product works for everything as listed, except Japanese Beetles, I'm still having to spray my rose bushes and other ornamentals for Japanese Beetles. Product does not work at keeping them out of our yard. The product is excellent otherwise. Easy to use with our rotary spreader,

Rated 3.0 out of 5.0 by cyoung111am it's done some good but didn't eliminate all grubs
I have just put down another bag of grub ex but the rain didn't move in so it hasn't been watered in the ground.
Will this cause the product not to work?

Need to get rid of those Japanese beetle grubs before they go to work on your lawn? Try Scotts Grubex. If you apply it to your lawn before the Grubs are active, and then again, about two or three months from that point, you will succeed in keeping your grass intact and the Moles will not have any supper. However, it does upset the Crows, who love grubs.

Rated 5.0 out of 5.0 by Doug57 Great product
I had this 10x10 area in the back yard where the grass was always dead looking. So I checked the Scotts website to see what the problem might be. The website told me to check for possible grub damage. So I got my square shovel and lifted a one foot square piece of sod up, and oh my god the grubs. They were eating the roots of the grass causing the lawn to look like dead grass. So I used the GrubEx the next summer, and I haven't had any grub problems, and the back yard never looked better.
Thank you Scotts for a great product. [This review was collected as part of a promotion.]

Rated 5.0 out of 5.0 by 57odin68 GrubEx is easy to apply using my Scott's Spreader
Several years ago my back lawn was being damaged by grubs. In talking with a friend of mine, a golf course supt., he suggested that I used GrubEx to correct the problem. The key, however, is to apply the product at the right time; therefore, I try to apply GrubEx the last week in May or the first week in June, weather permitting. I've found if we have two successive rain days that is the ideal time is to apply GrubEx -- after the first rain which softens the soil and prior to the next day's rain to wash it in. GrubEx has solved the grub problem for me and I use it every year.
I also like to use in the early spring season Scotts Turf Builder/ Halts Crabgrass Preventer. I've found the fertilizer kickstarts the lawn with a lush green color and the crabgrass preventer does a remarkable job preventing weed growth. [This review was collected as part of a promotion.]

Rated 5.0 out of 5.0 by Jimmiy It does exactly what you want to accomplish-eliminates grub worms
I have had grubs for 3 years in n a row which almost killed most of my lawn. Since I have been applying Gurbex annually for several years there is no trace of grubs. My lawn is beautiful and the best in the neighborhood. [This review was collected as part of a promotion.]
