Cankerworms

This tiny little bug causes BIG damage to trees and Charlotte is faced with a growing population of Fall Cankerworms. Last fall, it was estimated over 40% of the trees in the area were infested.

Cankerworms emerge as adult moths that climb trees in the fall. Once there, they lay eggs on the bark of smaller branches and twigs. The eggs hatch in spring and the larva feed on opening bud and young leaves, often skeletonizing them. This loss of foliage leaves the trees more susceptible to the effects of drought and more prone to infection.

The Cankerworm is a native to Charlotte. Its favorite tree leaves to munch on is the Willow Oak, although it is also found on other trees such as other species of Oak, Maple, and Cherry.

Two years ago, the City conducted an aerial spraying to help control the fall Cankerworm population. Although the spray was successful, it is still important for residents to band their trees this fall.

Banding trees in November and December helps to control the Cankerworms. Banding is done by applying a glue barrier to the tree trunk. The wingless Cankerworm moths are trapped as they climb the tree. For best results, trees should be banded around the last week of November, or as a good reminder, Thanksgiving. It is important to wait until most leaves have fallen from the trees so they don't get stuck to the tree bands.

Do not try to band your trees if you are not familiar with the process.
