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.

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.

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.

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 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  Great Grub Control
    By Jim in Chelsea, AL on 02/05/2016

    I tried to control the grubs in my lawn with the typical products carried by Lowe's or Home Depot with little success. Some of those products had a small amount of Merit. This % concentration of Merit has done the job. Applied early enough, no grubs. Even if I do not get it down before they start to show up in the yard, the late application gets rid of them.

    Had bad problem with grubs destroying front yard, even when a pro treated the yard. I took matters into my own hand and ordered Merit from DoMyOwnPestControl.com the following year and applied around July 4. This will be the third year I applied. I use organic lawn products and Merit and now have a great yard.

    I have had Merit applied to my lawn with confidence for several years by a lawn care company. However, Two years ago I noticed I had a big problem with grub infestation; after I paid a lawn care company to apply it. I noticed in the fall of that year bare spots in my lawn. I now apply it my self with, Do my own pest control and Merit, and I do it with even more confidence.

    5 of 5 stars  Merit works the first time.
    By Kirk in Folsom Ca on 04/23/2013
    Verified Purchase

    For years I have purchased product from the big box stores. These grub killer products never work. I fought grubs for years until I used merit 0.5 granules. To really find out if it works, I rolled back some of my turf and located 12-14 grub per square foot. I rolled the turf back and applied merit 0.5 granules, one week later everyone of the grubs turned a root beer color and were dead. HERE IS THE KEY. Grubs have a 3 year life cycle. Also during the night, moths from your neighbors lawn fly over and drop eggs. You will always have grubs trying to attack your lawn, just apply Merit 0.5 granules each year and it will stop the grubs dead for that season. No more dead spots in the lawn.

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.

QAre Merit Granules safe to use on a lawn where we have wildlife such as birds and rabbits?
is Merit Granules safe to use on a lawn where we have wild life, like many varieties of birds, also rabbits. We also have cats. I will not use any product that threatens to kill or cause wildlife or any animals to suffer in any way. Our grub situation appears to be quite serious suddenly. We are in KS, it has been warm & I think they are hatching or whatever they do. We have about 2 acres. Thank you.

AAs long as you follow the product label and keep all animals off of the area during the treatment and for a couple of hours following the treatment you should not have any issues at all. Do you know what kind of grubs you are dealing with? If you are dealing with Japanese Beetle Grubs you could also use St Gabriels Milky Spore which is non-toxic to animals and people at all stages. You can check with your local cooperative extension office to see what kind of beetle grubs you are dealing with if you are not sure.

QWill merit be a good defense against white fly and how long will an application last on ficus hedges?

AMerit WSP and Merit WP are good choices for white fly on ficus. You can expect an application to last 3-6 months but depending on the size of the ficus it may take 1-2 months to see the begininng result as the product must translocate through the ficus. While you are waiting for it to work you can do foliage sprays with Talstar P for immediate results.  Merit Granules (the product you referenced in your question) is not labeled to deal with whitefly on ficus because its usage rate is much different.

QCan Merit Granules be used as a systemic treatment for trees?
Bayer sells a product, "12 Month Tree and Shrub Protect and Feed" which contains 1.1% Imidacloprid plus some fertilizer. Can I substitute Merit granules or ImiGold for the same systemic tree treatment if I adjust the dose to account for the lower percentage of Imidacloprid?

AMerit Granules and Imigold Granules can be used for trees but is only labeled to treat white grubs when used for tree applications. Merit 75 WSP or the less expensive Adonis 2F is most often chosen to use for systemic root drenches on trees and shrubs.

QThe Merit 0.5 label doesn't list settings for Scotts Edgeguard spreader. What setting should I use for 60lbs/A
I'm using a Scott's ProEdgeguard broadcast spreader (setting dial 2-15). Product is Merit 0.5 granules.

A

We do not know the setting for that spreader and we are not sure exactly what to set it on.  However, almost all fertilizers, herbicides, insecticides, etc have treatments in amounts of so much product per 1000 square feet.  So if you can figure out what your walking speed is then you know anytime you apply any product that calls for so much of it per 1000 square feet, you always set your spreader on this setting.  You can calibrate this by marking off a 1000 square foot (10 x 100) area and placing 1.4 pounds of any type of product of similar granule size, or of the merit itself in the spreader.  Start with a low setting and start walking your marked off area at a normal pace.  You can adjust as you go and find the basic setting for you to apply the product over a 1000 square feet. The 60 pounds per acre equates to 1.4 pounds per 1000 square feet.  Or, you can call Bayer, the manufacturer, and they may be able to tell you what setting you should have it on.  You can reach them at (800) 331-2867.
