Our area in and near Charlotte, has the unfortunate distinction of being the heart of cankerworm activity in North Carolina. In fact, inexplicably, parts of Charlotte exclusively suffer from a quite intense infestation. Tiny caterpillars emerge in the early spring when leaves just begin to open (around late February) and feed immediately. As a tree’s young leaves and buds are destroyed, plants may respond with new buds and leaves, recovering fairly well. However, the damage is still unsightly. Cankerworms generally don’t kill trees, but this defoliation can drain a tree of some of its energy and may make it weaker.

Cankerworms are “inch worms” that measure up to one inch in length and may be light green or dark green. When the caterpillars have completed feeding, they will string down to the ground on a silken thread and burrow into the soil to make a new cocoon.

If you want to get the knowledge you need to understand and combat these pests well,  I suggest that you go to the following link, and join in for a live, on-screen conference with David Fogarty of NC State University and Gaston County Extension for an informative training,  Nov 03, 2017, 12:00 p.m.. Once you follow the link, check that your sound is turned up, and follow the on screen instructions, allowing the program “ZOOM” to launch.
