The aerial application of Btk has been determined to be the safest and most effective method of eradicating populations of gypsy moth in forested, semi-rural and urban areas. Gypsy moth larvae feed throughout the canopy of trees.
Trees come in many shapes and sizes and are located in all types of locations and terrain.
Some of these locations may be very difficult to access from the ground. Aerial application of Btk is the most effective and cost-efficient method of applying Btk over a large area and reach foliage located in poorly accessible locations. Furthermore, and most importantly, over 30 years of aerial application on human populations have revealed no short or long-term adverse effects to human or environmental health.
