Cornelius is facing a growing population of cankerworms (inch worms). Cankerworms are small green caterpillars that feed on the leaves of deciduous trees. In most cases, the cankerworm will not kill the trees;
however repeated defoliation can weaken trees and make them more susceptible to other stresses, such as age, drought, other insects and disease.
The easiest most cost effective way of controlling cankerworms is to band the trees and now is the time to do it. Band the trunks of susceptible trees and then apply with a sticky adhesive, such as Tanglefoot, in order to trap females as they crawl up the trunk to lay eggs. Trapped females may remain attractive to the males, which also get stuck in the sticky band. Banding supplies can be purchased at most local hardware stores.
