How much Hi-Yield 38-Plus Insect Control per gallon of water do I need to treat bark beetles?
To prevent infestation of Ornamental Trees and Woody Shrubs, use 0.3 to 0.6 fl . oz (2 To 4 tsp.) of Hi-Yield 38 Plus per gallon of water. Spray the bark to the point of saturation, but do not let runoff occur. Repeat treatment every 21 days during early Spring until Mid-Summer.
