Application Rate:
For trees with less and 2.5 inch DBH (diameter at breast height), inject one shell per stem. For larger trees, inject one shell every 4 inches, evenly around the trunk of the tree, below all major branches.
Timing of Injections:
Use year-around, unless bark is frozen to the point of preventing shell penetration. Use in all weather conditions, including rain.
