We do not know the settin of that spreader for application Merit granules. 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.

Please check out our Grub Guide for tips on how to kill and prevent grubs. There is a lot of useful information!
No, Merit cannot be used in a vegetable garden for grubs. We recommend contacting your local cooperative extension for advice. These centers have master gardeners that are familiar with regional pests and regional vegetation and can offer advice on safe products to use in your vegetable garden.
Merit can be toxic to bees that it contacts directly. We do not recommend applying Merit or any other insecticides while pollinators are present or directly onto flowering plants where pollinators are likely to forage.
Per the manufacturer, the chickens can re-enter treated area after the application of Merit Insecticide Granules has dried.
Treating for grubs can often vary from region to region and can change with the weather you have each season. It is best to apply your grub control products in mid-June to mid-July, before the grubs hatch. The eggs hatch in the fall, and grubs feed on turf in fall, overwinter underground, and then feed again in the spring. You will see damage during both of these seasons. For more specific timing for your area we would recommend contacting your local county extension office. We also have a treatment guide with more helpful information on grub control.
Merit Insecticide Granules can last up to 4 months. If you applied in late June, you would reapply around Novemeber.
