Step 2: This application occurs in early to mid-April.

The primary pest at this time which most people are familiar with is the Eastern Tent Caterpillar. Although they hatch from a black egg mass less then 3⁄4" long these creatures will do considerable damage and can completely defoliate a tree. If possible a pest monitor will first try to prune the nest from the tree by hand. Otherwise a liquid spray is used to penetrate the nest. Applications are also made at this time.
