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.

works - haven't seen grubs in the soil

I definitely had grubs - found quite a few digging around the yard here and there. I applied this product a couple of years ago, and subsequent digging has not turned up any grubs. My initial goal was to help eliminate moles! I had a pretty major mole problem, and eliminating the excellent food source grubs provide goes a long way towards that yard battle.

Used twice and the grubs and japanese beetles are still around

I had a new lawn laid last spring (May 2011) and noticed japanese beetles on my grape vines (July through Aug. 2011) plus dead patches on my new grass. I put GrubEx1 on my lawn in Aug. to no avail. Again I put GrubEx1 down last May (end of May 2012) and watered it in. This spring I got rid of the grape vines because the beetles destroyed them last year. For a week now I have noticed beetles flying around my yard and my back yard (new grass last spring) is a disaster... many dead spots. For some reason the beetles have been landing on my two umbrella's on my deck, where I have drowned at least a couple hundred in a bucket of soapy water. The thatch in the grass has become thick because of the grubs eating the grass roots. I'm going to the store today but this time I'm going to try something else.

We are sorry to hear of your experience with Scotts GrubEx1. 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, we recommend putting GrubEx1 down April through July, with the best time being April-May. One reason for the early application is to make sure the active ingredient is washed into the soil. If you apply it too early in the spring, the active ingredient will break down before prime grub hatching time. If you apply it too late it will not be effective on those grubs hatched early in the year. Unfortunately Grubex1 does not kill Japanese Beetle adults, and will not prevent new Japanese Beetles from entering the yard. 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 contact us to see what can be done.

The product works

After switching from a lawn service to managing my own lawn, I had a problem with grubs due to lack of experience in treating my lawn. I applied Scotts Grub-X and the problem was resolved. Since then, I apply it annually and the problem has not reappeared.

Big Joke

I bought 5 bags of this stuff and put it on even extra and made sure it was watered like directed. I now have more tunnels than I had before, not sure but must have fed the grubs instead of killing them. This was the biggest waste of time and money for something that was guaranteed.

Failed

I applied the grub treatment in early May. I have noticed severe patches of dead grass. I originally assumed it was from lack of rain. I began watering religiously. The yard started to look really good with the exception of the same patchy dead spots. I decided to dig and found live grubs. Very frustrating!

We're sorry to read about your disappointment with Scotts Grubex1 Season Long Grub Killer and appreciate your feedback. For best results, this product should be applied as a preventative in the spring or early summer (before the 4th of July) before damage is present; once damage is noticed, it is too late. GrubEx is not effective on mature grubs. This product must be immediately watered into the soil before it will be affective and must be applied to the entire lawn for complete control. 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.

Great stuff - lawn saver!

I live in a suburban/rural setting and, while many people think having wild turkeys around, it stinks because they tear my lawn to shreds! I found that they are really digging for grubs and Japanese beetles. That's where the Grubex comes in. Last year, I put Grubex down on 85% of my lawn (ran out before I finished). No turkeys on that 85%, but the other 15% took a beating! No more excuses this year. The entire lawn got a full cover. This product is a little pricey, but I don't have a lot of alternatives.

Rids Japanese Beetles

When we first moved to our property, the Japanese Beetles were terrible in mid-summer. They ate every nice planter/flower my wife would put on our deck. I began using Grub Ex yearly and the Beetles haven't been seen since, knock on wood. They're still in the area because I see full bags hanging in yards all summer but our yard has been spared. I can only attribute it to Grub Ex.

Works Great Except.

I do not have a large lawn in Noethwest Florida. I have a buffer area behind my home that is quite large. Have many critters that come from the preserve and armadillos. I have been dealing with armadillos for years. Decided to challange the armadillos head on. I put down the Grubex all over my entire yard. Including the bushes and areas that has a lot of pine bark. Watered in as directed. I now have little damage in the bush and grasssy areas. However, All the beds that have pine bark has become a buffet. I tried putting down more Grubex, in thae area, watered it in well and the armadilos have not stopped digging in that area at all. I went out this morning 5/18/24 and they dug up the entire area of that has the pine bark. I took photos but the ability to ad photos was not working.

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.
