Great Product

[This review was collected as part of a promotion.] The consistency of the product is very thorough. The packaging was nicely sealed and made for nice application. It seems to have pretty strong durability against grubs so far and a little dosage really does go a long way.

Good for prevention

[This review was collected as part of a promotion.] This bag covers 5000sq ft. Following the instruction on the bag, I used a Scotts spreader set at 3 and 1/2 and I ended up having about 10 to 15% left over. I lowered the setting down to 2 and 1/2 and went back over the lawn to kind of even out the coverage with the remaining amount. The granules are very small and fine which helps it spread evenly and easily. I haven't noticed it killing active grubs but it has helped keep the population down later in the season.

Scott's grubex season long grub killer

[This review was collected as part of a promotion.] The setup to get everything done is simple and easy to do. This product is very portable and you definitely get value for your buck. I like that it explains how to use it on the bag. And the packaging is very clear and self-explanatory.

Easy to apply, great coverage, and a simple way to protect your lawn from grubs all season long.

[This review was collected as part of a promotion.] Easy to apply and seems to do exactly what it promises. The granules spread evenly, and after watering it in, I noticed a big improvement in my lawn. Great preventative treatment for grubs and gives peace of mind for the season. The bag covers a large area, making it a good value for maintaining a healthy lawn. Would buy again!🌱😊

Easy to apply

[This review was collected as part of a promotion.] This product is so good for the lawn and easy to apply to the grass. It is easy to clean up and provides season long protection. It protects against grub. It is a nice thing to try out for the lawn and love all lawn care items from Scott's.

Grubex, Grubs and Moles

It works! Haven’t had grubs when I have used. The year I didn’t use I had grubs and moles moved in to dine on the grubs. I had to hire a mole trapper to get rid of moles. Started using Grubex again and haven’t had a problem with grubs or moles since!

Great Grub Control Product

Great Product! Never had a Grub issue since i have been using this product for well over 10 years. Put it down in late march or early April so it has a chance to get into the soil well before the grubs start doing their damage. Expensive but it would cost a lot more to redo your lawn from the grub damage.

Lush grass again

[This review was collected as part of a promotion.] My grass looked awful before using Scott's GrubEx. After just one treatment in looks full and green again. I even have enough to treat my lawn again in 4 months. I love the convenient packaging. Of course if you have pets they should be off of the grass until the modules are watered and completely in the soil, my dog just loves rolling and playing in our grass.

Get ahead of the critters

Hopefully I'll get the best of the grubs this time around.

It does the job!

[This review was collected as part of a promotion.] The results are great and no bites from bugs on either one of my plants. I would suggest doing this once a month no more. I store The rest of the products in a dark cool area. Not much of a mess prefer to use the equipment that uses to spread on the yard. The product is a dark grainy substance. Easy to shake around throughout the yard.
