We don't have the exact spreader setting for your model spreader. The easiest way to determine the correct setting to apply Howard Johnson's Bifenthrin Granules is as follows: If you need to use 1.15 lbs of product per 1,000 sq ft, then you would add 1.15 lb of product to spreader, start with a medium setting, then apply product to a 20 x 50 ft area (1,000 sq ft).  If you have product left, your setting is too low.  If you run out of product, your setting is too high
