Abe from Miami Beach Florida writes,
How often must one apply Arena .25 Granules against whitefly for ficus in Miami area?
Arena Granules should be applied early in the shrubs annual growing cycle, so you will generally treat once a year. Treatment may be repeated as long as you do not exceed the maximum rate of 160 lbs per acre per season. Be sure to follow all the product label directions for best results.
