Tree bands, coated with a sticky non-toxic substance known as Tanglefootâ„¢, trap the female cankerworm as she marches up the tree. Bands are applied before the first frost in the fall and removed in May to allow the bark to dry out over the summer.
Cankerworms feast on elm, ash, maple, linden, oak, fruit, and ornamental trees. They can leave a tree completely stripped of leaves. If needed, trees can produce a second set of leaves mid-summer. However, this weakens the tree and makes them more susceptible to insect attacks and diseases (i.e. Dutch Elm Disease). Repeated defoliation year after year can lead to limb dieback and can ultimately kill a tree.
Yes. Tree banding is an effective long-term measure that reduces the cankerworm population. The repeated act of tree banding over many years is required to break the cankerworm's natural cycle. It is great to see the reduced levels of cankerworms in the areas of the city we have been banding for twenty years.
We are the only service in the city using authentic tree banding supplies. Using non-authentic supplies makes tree banding useless.
