The Gypsy Moth Caterpillar Problem

Insect Control - The  Gypsy Moth Caterpillar Problem - Gypsy  moth caterpillars are voracious eaters.Gypsy moth caterpillars are voracious eaters. They defoliate millions of acres of trees annually. When they hatch, they feed (mostly nocturnally) on the leaves of trees and shrubs. They can completely defoliate an entire tree in one season. Even a partial defoliation can severely stress a tree, putting it at risk for secondary pests or diseases. Depending on the type of tree and its health, defoliation or repeat defoliation can significantly weaken or even kill the tree. Extreme defoliation can kill a low vigor tree after one year.
