Cankerworms are pests that threaten the health of trees in Durham and throughout the United States. You have probably seen these little, green inchworms falling on threads from trees in the Spring covering sidewalks, cars, and people. Aside from being inconvenient, cankerworms feed on leaves of trees and shrubs, weakening plants and increasing their susceptibility to pests and environmental stressors such as drought and heat.

Cankerworm Outbreak

Cankerworms have reached outbreak levels over the last few years in Durham. This abundance is partially due to the cankerworm’s affinity for over mature willow oaks, like those that line the streets of Durham’s neighborhoods. The cankerworm’s extensive feeding leaves Durham trees even more vulnerable to dying.

Thankfully, we can control outbreaks of cankerworms. Read this fact sheet about these pests and what you can do to protect our trees (PDF).

Get Materials to Band Your Trees

There are several places for you to get materials to band your trees.

You can purchase banding materials and Tanglefoot at Stone Bros & Byrd garden center and Durham Garden Center.

You can purchase reuse materials to make your own bands at the Scrap Exchange.


Materials are available at the County Cooperative Extension (721 Foster Street) and the City of Durham General Services Department (2011 Fay Street) Monday-Friday 8:30-5:00. Materials include fabric and plastic to band two medium sized trees (approximately), information sheets on how to band a tree, and a sign to put on your tree.  We cannot offer staplers this year.  We are continuing to look for other options for making the full kits available and will update this site when that becomes available.

Here is a tag you can print and attach to your band so people will know what the band is for and get inspired to band their own trees.

Don't forget the timeline!

Goop it - Thanksgiving
De-band it -  March 17  - MAY 1
