Protect Trees from Harm

Banding Together to Fight Cankerworms

Charlotte is faced with a growing population of fall cankerworms, despite aerial spray efforts in recent years. Now more than ever, it is vitally important for residents to band their trees each fall. By continuing to band our trees, we can prevent the cankerworm population from increasing to an unmanageable level.

A common, native pest of hardwood trees, the caterpillars can cause defoliation in our tree canopy. When cankerworms hatch, many descend on silk threads, get caught by the wind and “balloon” to surrounding trees. They prefer Willow Oaks, but feed on more than 50 other plants, after which they drop to the ground, burrow and form a cocoon.

If you are concerned about small trees and shrubs in the yard, talk to your garden center folks about sprays – follow directions carefully. An arborist can be consulted about larger trees. The best defense is banding with tar paper and Tanglefoot in early fall.

The City of Charlotte offers a matching program for tree banding, and neighborhoods can apply to Charlotte’s Neighborhood Matching Grants Fund for up to $3,000 toward banding trees. The City of Charlotte provides additional information about cankerworms and tree banding, including retailers with tree banding supplies.

Emerald Ash Borer

The Emerald Ash Borer is a non-native invasive insect that has already killed tens of millions of ash trees in North America and is slowly but steadily moving into areas of North Carolina. Susceptible trees in North Carolina are green ash, white ash, Carolina ash, pumpkin ash and white fringetree. This beetle can spread naturally (by flying) or through the accidental, human-facilitated movement of infested material such as firewood or ash timber.

The North Carolina Forest service developed a map that tracked detections of the Emerald Ash Borer in the state, including Lincoln and Iredell counties. For more information about the Emerald Ash Borer, visit the North Carolina Forest Service site.
