Customer Reviews
John Peterson
“Outstanding results!”
I started using GrubEx Season Long Grub Killer last spring, and the difference has been remarkable. Before, my lawn was constantly plagued by brown patches caused by grubs, despite my best efforts to reseed and water regularly. Within weeks of application, I noticed a dramatic improvement—no more skunks digging for grubs, and my grass stayed lush and green all summer. The granular formula made it easy to apply with my spreader, and I appreciated the peace of mind knowing that my lawn was protected for months. Highly recommend it for anyone struggling with lawn pests!

“A game-changer for lawn care!”
I’ve tried multiple insecticides over the years, but GrubEx2 exceeded my expectations. Living in an area with heavy Japanese beetle infestations, my yard suffered from dying grass every year. After applying GrubEx2 in early June, I saw immediate benefits—no grub damage, fewer beetles, and healthier grass growth. It’s easy to apply, and unlike some other treatments, I didn’t experience any strong chemical odors. A must-have for any homeowner serious about maintaining a grub-free lawn!

“Saved my lawn from disaster!”
Last summer, my front yard was destroyed by European chafer grubs, leaving huge bare spots that wouldn’t recover. A friend recommended GrubEx3, and I decided to give it a shot. I applied it in early spring, and by mid-season, my lawn was greener and thicker than it had been in years. What really impressed me was how effectively it prevented further infestations—this year, I haven’t seen a single sign of grub damage. The application process was straightforward, and I love that it provides season-long protection with just one treatment. Worth every penny!
GrubEx FAQ
When is the best time to apply GrubEx to my lawn?
For maximum effectiveness, you should apply the product in late spring or early summer (typically April through June) to kill the next generation of grubs before they hatch and begin feeding on your grass roots.
Does GrubEx need to be watered in after application?
Yes, you must water the lawn with approximately 1/2 inch of water or wait for a steady rain within 24 hours of application to move the active ingredient down into the soil where the grubs live.
Can I apply GrubEx and fertilizer on the same day?
You can safely apply both on the same day, though it is generally recommended to use a spreader to apply them separately to ensure an even distribution of both the pesticide and the nutrients.
Is GrubEx safe for pets and children to walk on?
Once the product has been watered in and the grass is completely dry, it is safe for people and pets to return to the lawn and resume normal activities.
Does this product kill active grubs in the fall?
GrubEx is primarily a preventative treatment designed to stop new grubs; if you already have significant brown patches and visible larvae in the late fall, you may need a “24-hour” curative killer instead.
Will GrubEx help control Japanese Beetles?
By killing the grub larvae in the soil, you are effectively reducing the population of adult Japanese Beetles that would otherwise emerge from your lawn later in the season.
