Tree Banding for Cankerworm Control
MOOSE JAW - The City of Moose Jaw is reminding the public that cankerworm season will be upon us in the next month or so. If you banded your trees in the fall, it is time to re-grease them now. The grease traps catch the female cankerworm moths, preventing them from crawling up the trunks of the trees and laying their eggs. If you didn’t band in the fall, it’s not too late.
How to band a tree:
- All elm, Manitoba maple and fruit trees on or adjacent to your property should be banded
- Wrap a four to six inch wide strip of fibreglass insulation around the trunk – about five feet off the ground. That’s out of reach of pets and young children.
- Cover the insulation with a sheet of plastic wrap or cling wrap. Allow several inches of plastic above and below the insulation. A black plastic garbage bag will do.
- If you are using plastic wrap, tape the plastic to the tree with duct tape. If you are using cling wrap then the duct tape is not required. Do not use nails or stakes.
- Spread a layer of a sticky substance, such as axle grease or petroleum jelly on the plastic.
- Inspect the sticky material regularly and remove leaves, insects and other debris and reapply sticky material if required.
- Bands should be removed by mid-May and no later than mid-June. Removing the bands prevents damage or discoloration of the bark.
- Bands should be reapplied in September for control of fall cankerworms.
