Ashton from Metairie, La writes
The Hi-Yield Bug Blaster Bifenthrin 2.4% product label does not restrict the use of the product on azaleas bushes or shrubs. The mix rate per label instructions is 0.5 fl. oz. (1 Tbs.) per gallon of water sprayed over 167 sq. ft. Spray evenly over foliage and treatment surfaces to the point of runoff. Repeat application is necessary only if there are signs of renewed insect activity. Repeat application must be limited to no more than once per seven days.
