Long lasting for healthy grass

[This review was collected as part of a promotion.] Really in love with this product. Lawn maintenance is no easy task but this grub killer makes it that much simpler to having robust green and healthy grass. Now is the ideal time for this product because it’s currently rainy season where I live. This should ideally last at least 4 months!! I look forward to easier lawn care this year.

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.

NO GRUBS

[This review was collected as part of a promotion.] Scott’s GrubEc was extremely easy to apply. It takes just a couple minutes to walk the spreader along your lawn and then just water to activate the product. Now I don’t have to deal with pesky grubs for the season! Great product.

Fine grub killer

[This review was collected as part of a promotion.] Scott’s GrubEx Season Long Grub Killer was easy to put down. It does have a dusty smell so maybe wear a mask when pouring it into your dispenser. I put it down and three weeks later there is no noticeable difference in my lawn.

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.

Best grub killer

[This review was collected as part of a promotion.] Scotts GrubEX is the best product for grub killing. Last year my lawn was horrible. I had so many issues using a lawn service company to treat my lawn. They ruined it. This year I decided to do it myself. We used scotts grub killer. It was so easy to use. And very safe to use on my lawn. My lawn looks so much better already. The bags design is perfect to unload the product. It absorbs easily into my grass. We had no issues at all. Definitely recommend this product for everyone that has grubs ans lawn issues.

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!🌱😊

GrubEx: preventive insecticide that protects your lawn for four months with a single application .

[This review was collected as part of a promotion.] I have been using Scotts GrubEx1 Season long Grub Killer for a few seasons now, and it is a total game-changer for my yard. Last year, my lawn suffered from massive brown patches due to a severe grub infestation.

Effective grub killer treatment

[This review was collected as part of a promotion.] Scotts Grubex grub killer is active and effective in killing the active grubs that deteriorates the lawn and keep them drying and brownish. It is easy to use, provides long lasting protection and safe to use. You see the results best when applied early spring to summer onset season with active watering post application.
