Since Merit Insecticide Granules is a systemic insecticide, you want to apply it several weeks before egg hatch 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. Under normal circumstances, Merit will provide residual white grub control for four months or longer in turf.
Merit 0.5 G Insecticide Granules can be used in landscaped ornamentals but not in any edible gardens.
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. You can calibrate 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. You may also contact Scott's directly for help with calibration and recommended settings for your specific application.
Merit Insecticide Granules are not labeled to eliminate mealy bugs or to attract them.
Merit Insecticide Granules are not labeled to control or kill ticks. We advise that you look at the DeltaGard G Granules for tick control. According to the Delta G Granules, a regular treatment program should be followed. Treat once a month when pests first appear in late spring (May-June) and continue until late summer (August-September) in the fall.
Merit Granules are a great choice for grubs, just be sure you are applying before egg hatch so that the active ingredient has time to work systemically. There are some spreaders listed on the product label, however yours is not one of them. We usually recommend starting around one setting below the middle setting and then adjusting as needed.
For your more general pest prevention, Talstar Xtra Granules would be a great choice.
