  • Alternate Image 1

Merit Granular (by Bayer) is the longest lasting broad-spectrum grub control product on the market. Both curative and preventative, Merit Granules are effectivene on virtually every species of turf and ornamental pests. Merit even improves the quality of your turf. Merit 0.5 G is for broadcast application on and around turfgrass, ornamentals, trees, shrubs, flowers, groundcovers, and in and around commercial or residential buildings. Apply Merit 0.5 G uniformly over area being treated with normally used granular application equipment. Both drop-type and rotary-type spreaders may be used.

Merit Granular (by Bayer) is the longest lasting broad-spectrum grub control product on the market. Both curative and preventative, Merit Granules holds a ten-year record of 90% effectiveness on virtually every species of turf and ornamental pests. Merit even improves the quality of your turf. Merit 0.5 G is for broadcast application on and around turfgrass, ornamentals, trees, shrubs, flowers, groundcovers, and in and around commercial or residential buildings. Apply Merit 0.5 G uniformly over area being treated with normally used granular application equipment. Both drop-type and rotary-type spreaders may be used.

Tips for Use

MERIT is most effective when applied prior to, or just after, egg lay. In most cases, adult emergence occurs in early summer, often after significant rainfall or irrigation, followed by mating and egg laying. This usually continues for four to six weeks. Under normal circumstances, Merit will provide residual white grub control for four months or longer in turf.

    5 of 5 stars  Grub control that works
    By Jim in Chelsea, AL on 04/04/2011
    Verified Purchase

    I have spent hundreds of dollars on different grub control products each year with the same result: grubs. Last year I discovered the 0.5 G Merit and thought that the extra strength might get it done. After years of frustration, this product worked as advertised.

    By Clarence in Hernando Beach, Florida on 07/03/2011

    I have used this product now for several years and find that it is the only way to control my problem bugs. "Do My own Pest Control" has been a Godsend for me. Im able to afford to continue treating with Merit 0.5 granules and shipping was free. Im so happy I found "Do My own Pest Control". I plan on doing business with you for many years to come.

    5 of 5 stars  This stuff works
    By Doug in Huntington Beach CA on 09/09/2012
    Verified Purchase

    I've been fighting with white grubs destroying my marathon 2 lawn for several years and had tried several products before, but they barely slowed down the spread. After one application of the Merit Granules the spread of the dead areas has ceased and visible recovery has begun. If you have white grubs, this stuff works.

    5 of 5 stars  best product ever
    By David in pembroke pines,fl. on 09/18/2010
    Verified Purchase

    last year i awoke to find my yard over run by crows. During the day i would run outside and chase them away but they would return within the hour. The crows were destorying my lawn. So i called a professional lawn service and they promise to treat and end the problem. The day after the lawn was sprayed the crows continued tearing up my lawn. Even after a month later. At that point i searched the internet and found a product called" crowbegone". A cd with strange bird calls but after a month of use it to was a failure. The crows had won so i thought. Thats when i came across your wed site and purchase Merit G. In two words "It Works ". After chasing away the crows i applied Merit G and watered it in real good that evening. Within the first week i observed fewer crows on my lawn. By the second week the crows would land on the lawn and walk around looking for their grub meal but the kitchen was closed. After a month only one or two crows would check out the lawn and then walk away. Problem solved. Now my lawn is beautiful again. THANKS.

  • 5 of 5 stars  Works like a charm
    By Jane in Cedar Grove, Indiana on 07/12/2017

    This is our second year purchase of Merit because we missed a corner of the yard last summer. We are treating 2 1/2 acres and before last summer, we had a significant infestation of grubs and moles. It is very obvious where we applied the Merit and where we missed. Over all the lawn is grub free except a small patch far from the house and near the road. Follow the directions for your location and it does work like a charm.

    5 of 5 stars  Merit Insecticide Granules
    By Kmcd in VA on 08/19/2016

    This product is great. Since I started using my mole and vole problem has disappeared. However, I was disappointed to find that this bag was delivered with a large hole that someone attempted to seal with tape which did not hold up during the mailing process. I would have returned it but was short on time and needed to spread the granules quickly.

    5 of 5 stars  MERIT controls Hemlock Wooley Adelgids
    By Jim in Franklin, NC on 07/17/2016

    When the Wooley Adelgid arrived in our area and started killing our beautiful hemlocks, we found that treatment with MERIT was extremely effective in protecting our trees. Although the trees in our woodland were too numerous to treat them all, those we treated survived, and those we weren't able to treat did not. We'll always be grateful for the trees we were able to save, and for the MERIT that made it possible.

QHow safe is Merit Granules around pets?
8000 sq ft yard, when will it be safe for my 2 small dogs to go back on the lawn after I treat it?

AYour pets should be out of the yard while you are applying the Merit Granules and while you are watering them in. Your pets can return to the area after the surface of the grass is dry, usually after about 5-6 hours.

QWhat should I use for grubs on my lawn?
Merit granular, Bayer or your suggestion? I am ready to attack!

AMerit Granule is actually manufactured by Bayer and is always our top recommendation for grub control. For best results, make application prior to egg hatch. To find out when grub egg hatch normally occurs in your area you should contact your local cooperative extension office.

QWhat happens if you apply Merit more than once a year?
i keep seeing that you should only apply it once a year. But what does it do if it is applied twice? I can't find any information on repercussions. does it harm the soil or the grass?

AYou are able to apply Merit more than once a year but you cannot apply more than 80lbs of Merit per acre per year. While it will not harm the soil or the grass the EPA does limit how much product you are able to use in a given area per year.

QWhen you apply the Merit granules, does the chemical stay in the soil and protect grass planted later on?
when you apply the Merit granules for example in late June, does the chemical stay in the soil such that if you plant grass seed a couple months later in Sept, will the new grass have the systemic protection as well? or would the new grass be unprotected?

AThe Merit that is applied will be in the soil for some time but it is trans-located through the plants that are in currently in place. Newly planted grass should be retreated.

QIs Merit safe for poultry, after it's watered in?
We have a horrible Japanese Beetle infestation and need to control it before it kills our fruit trees. Knowing it's too late for this season, would a summer or fall application of Merit work? And can we use it with Poultry, after a hold off period? We have free range chickens in our yard.

Per the manufacturer,†the chickens can re-enter treated area after the application of Merit Insecticide Granules†has dried.†

QWhen do I apply Merit 0.5 G for grubs in turfgrass in southwestern Michigan?

A

Since Merit Insecticide Granules is a systemic insecticide, you want to apply it several weeks before egg match of the target pest. Usually this application needs to be made in late Spring, usually†sometime between May and late June. We recommend contacting your local Cooperative Extension for the best recommendation on application timing for your target pest in your area.

QWhen is the best time to apply Merit Insecticide Granules for control of mole crickets in west central Ohio?
Is rainfall or watering necessary within 24 hours?

A

Since Merit Insecticide Granules is a systemic insecticide that translocates through the plant, it is best applied before Spring/Summer egg hatch, before we see adults and/or damage from the target pest, in this case before we see adult mole crickets. The granules do need to be activated with irrigation or rainfall of about 0.5 inches. For the most exact recommendation as to when to apply the product, we recommend contacting your local Cooperative Extension office.

QWhen is the best time to apply Merit Insecticide Granules in Dallas, TX?
I've seen grub worms in the last few years.

A

We recommend contacting your local cooperative extension office to ask about exact insecticide timing for the pests in your region. These offices are an invaluable resource when dealing with pests and most have a master gardener and an entomologist on staff to answer pest insect questions.

QCan Merit Insecticide Granules be used to treat scale on shrubs?
I have scale on some large holly trees. I heard the chemical in Merit would treat for them. Looking for something I can pour on the ground above the roots. (Systemic)

A

Merit 75 WP - 2 oz. jar†will treat scale insects. It would be better to use Merit 75 versus the granule.†You can apply this product as a soil injection or soil drench around the base, for the root system to soak up and translocate up. Please refer to the†Merit 75 Wp product page,†as we have listed the applications to trees and shurbs. Also, be sure to refer to the product label for application as well.†

QHow far away should I apply Merit Granules from my fruit trees?
My lawn has 3 fruit trees planted in it and a major grub problem.

A

Merit Granules should be at least 10 feet outside of the drip line of the tree. We would recommend using Milky Spore Powder instead. This product can be used around edibles and will kill and prevent grubs for up to 10 years. It only needs to be applied once.

Please check out our Grub Guide for tips on how to kill and prevent grubs. There is a lot of useful information!
