Very good grub treatmet

With a lot of rain in N. Florida and seeing both Lawn Moths and morning damage to my St Augustine Grass, I knew I needed a surface and deep treatment product. The GrubEx1 really did the job. One application in early August has taken care of pretty much everything, although I have to consider that the heavy rains might have washed some of the product out. The price was great and it is a very good alternative to other products. Scotts quality is always top notch and it will work as advertised. Look for it at Home Depot or Lowes for the best price.

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.

It works effectively

[This review was collected as part of a promotion.] I've tried other brands that weren't as effective. Aside from the cost, if you want to eliminate grubs this product works quite well. We only received a sprinkling of rain during the following ten days after my application and I was concerned it wouldn't take effect. It was enough apparently since the grubs are gone (and beetles) and the crows no longer tear up my yard, either. Buy it.

We're sorry Scotts Grubex didn't work to meet your expectations. This product is meant to be applied in the spring and watered in to activate the insecticide. If there is a thick layer of thatch (more than a half inch thick) it can stop the product from providing the assistance needed. If the grubs have grown into the mature stage the product will not kill them as they have already reached a phase in their cycle where they are immune to most insecticides. Once you start seeing damage, application of the product is too late. If you need assistance or have any questions please contact us via https://www.scotts.com/smg/gosite/Scotts-v2/help and one of our representatives will be glad to assist you.

Does not spread as much as directions say

I bought the smaller package for 5000 square foot lawn. I use the Scott's brand drop-type spreader set to 5 1/2 like the instructions say. When I opened the bag and saw how fine the granules are, I questioned whether 5 1/2 is the correct setting. But I went ahead and did it anyway. It didn't even last 1500 square feet and the whole bag was gone. I know there's nothing wrong with the spreader, because I had just used it the day before on the neighbor's yard with Scotts #1 Crabgrass Preventer and it worked perfectly.

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.

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.

Scotts GrubEx

This is the best product for eliminating grubs from your lawn. I moved into my current home 8 year ago. At that time I had grubs that killed the grass and moles all over. Their tunnels were very noticeable and the lawn was a disaster. For the first 2 years I tried everything on the market, including trapping these darn moles with no success . On a trip to a local hardware store I purchased (3) bags of Scotts GrubEx . After applying, everything changed with my lawn. No longer did I have grubs and moles but my lawn was revived and looked like a show case lawn. People commented on my "new" picture perfect lawn. For the past 5 years, my lawn has been mole and grub free great lawn

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.
