When using Bio Advanced 12 Month Tree & Shrub Insect Control Landscape Formula to treat shrubs, you will use 1.5 ounces of concentrate per foot of shrub height. So if you have 5 boxwoods and each one is 4 feet high, then you would apply 6 oz of the insecticide per shrub, for a total of 30 ounces. Please refer to the product label for complete application instructions.
