Marathon Granules

I may not have spelled this right, but has anyone ever used these on brug's I was told they work for almost 3 months at controling aphids and mites, which have just been terrible here this year.

We use them in the greenhouse, they work on aphids, mealybugs and scale, but not mites. They aren't an arachnacide. The active ingredient is imidicloprid.
