GrubEX

Bought this product today to treat grub worms in my yard. Had I realized that I needed 1 inch of water after applying to my lawn, I would have NEVER purchased the product. Disappointed.

Effective

I've used this product each year and it has always been very effective. My neighbor used another product and had skunks devastated his lawn to get at the grubs. My lawn was unaffected.

Light bag

The bag that covers 5000 ft.² does not cover 5000 ft.². I use your other products and the ones that claim they cover 5000 ft.² cover 5000 ft.². I end up buying two bags of Grubex.

We're sorry to read about your disappointment with Scotts Grubex1 Season Long Grub Killer and appreciate your feedback. Have you recently checked the calibration on your spreader? Some spreaders can go out of calibration over time and should be checked periodically. Did you overlap properly? With broadcast spreaders, you want to overlap about 1 foot on each swath. With drop spreaders, you want to line up your wheel marks. Were you walking faster or slower than usual? Your walking pace will affect the rate of application. We want you to be confident in our products. For this reason, we offer a product guarantee. If for any reason you, the consumer, are not satisfied with the results after using this product, you are entitled to get your money back. Limitations apply. At your earliest convenience, please reach out to us at 888-270-3714 if we can further assist.

Useless product and a complete waste of money

Bought 2 bags. Applied twice in the early and then late spring. My front yard is nearly completely destroyed by brubs. Useless product and a complete waste of money

Expensive waste

Doesn’t work and costs twice as much as the best brand I’ve used so far. Bought this after noticing a few holes and wanted to do some spot treatment. And even when putting a concentrated amount around certain areas it still didn’t work.

Mole Control

We've lived across from a golf course ffor 17 ye our mole problems were always bad until we started using Grubex to kill the moles food source. After seeing how good our lawn looks, all of our neighbors use Grubex too!

Good product, easy to use and effective

This is the easy way to control grubs. It is effective in most conditions, although I've found I needed to apply a second round in some areas more heavily infested. It seems to have been very effective this year even with the hot dry weather.

GrubEx keeps Japanese Beetles in check

We apply GrubEx once a year in early Spring in Ohio to prevent Japanese Beetle larvae from hatching. It has been very effective in controlling these pests.

Simply put- it works. No grub issues all summer

I applied the insect control in the early spring as directed. I had no issues with lawn insects. As a result I had much fewer voles in the yard. My lawn looks better as a result.
