The Fruit Tree Grease Band from Defenders is a simple and effective way to protect fruit and ornamental trees by controlling orchard pests, particularly winter moths, caterpillars, earwigs and ants. For best results, apply the grease band at the beginning of winter, before adult female moths emerge to climb the trees and lay eggs. Re-apply in summer to protect against ant infestations and summer crawling pests. Protect your trees and fruit by trapping the moths before they have a chance to lay eggs. Other harmful insects will not be affected as they are not attracted to the green colour.
