Solutions to Bark Stripping
Habitat Modification
- For isolated trees or groups of trees
- Wrap tree trunks with 24″ (or greater) aluminum flashing at least 6 feet off the ground to prevent climbing (see photo above by Stephen M. Vantassel). Flashing on trunks will reduce climbing access. Place 1/4-inch shives between tree and flashing to prevent mold from developing.
- Wrap 3 rows of porcupine wire, spaced with tines 2 inches apart, to help prevent squirrels from climbing. Be sure the porcupine wire is at least 8 feet off the ground to prevent people from accidental impalement.
- Remove or modify all bird feeders.
Repellents
- Limited value. Taste repellents can be effective to stop squirrels from gnawing on a particular spot. Read label to see if the tree would be harmed.
