Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. The City of Charlotte has one of the best urban tree programs in the country. You can visit their website at Charlotte Tree Plan to learn about how an urban forest provides numerous benefits to a city’s residents. Visitors to Charlotte often wonder why certain trees have what looks like bandages wrapped around their trunks. These are special treatments designed to capture fall cankerworm females. The foliage eating cankerworms larva pupate in the soil and adults emerge from mid-November through January. Fortunately, the females are wingless and simply walk up to the tops of trees to begin their egg laying. By applying a paper wrap coated with a sticky substance called Tanglefoot around the tree trunk, several feet above the ground and below branches, , arborists and home owners can itrap these females before they lay their eggs
