Tree bands are ready for sticky Tanglefoot material

Have you noticed all the black bands around trees on North Union Street or the McEachern Greenway and not known why you’re seeing them? The black bands help prevent cankerworms from hatching in the spring. These little crawlers, which migrated into Cabarrus County over the last few years, can be a big pest.

This year, the City of Concord, Cabarrus County, and the local Cooperative Extension Center have partnered to educate the public about cankerworms and how tree banding can be a highly effective way to prevent them. If you have not heard about cankerworms yet, be sure to click here to learn more about cankerworms and how to prevent them.
Female wingless moth with eggsThe cooperative effort was focused on getting the public ready for the optimal time to capture female wingless moths as they climb trees to lay the eggs. Now is this time, as the moths become active after two consecutive nights of below-freezing temperatures. The City’s Buildings and Grounds Department is now applying Tanglefoot to the trees previously banded in the cankerworm target areas, and residents are encouraged to do the same.
This sticky Tanglefoot material is safe for birds, squirrels, and other animals. It does not contain pesticides, but works by trapping the female moths traveling up from the ground to lay their eggs in the upper sections of the trees. Each female can lay hundreds of eggs, so each female that is trapped potentially represents hundreds and hundreds of captured cankerworms.
City staff recommends applying a small bead of the material at the lowest section of the band, and inspect for capture next week. Tree bands with activity should receive further applications of the material.
tree bandingResidents are urged to install their tree bands with Tanglefoot now, and to apply the Tanglefoot material to all bands installed previously. It is not too late to install bands, but it is important to get them installed as soon as possible.
