Grease bands and tree barrier glues are a pesticide-free method for preventing infestations of winter moth caterpillars in the spring. They stop the wingless females from climbing up the trunks of fruit and other deciduous trees and laying eggs.

Grease bands are mainly used to protect fruit trees, such as apple, plum, pear and cherry from winter moth caterpillars.
Note that sticky barriers give no protection against codling moth (the cause of maggoty apples), plum moth (the cause of maggoty plums) or other types of caterpillars. That pest has winged females that are active in midsummer.
It is important to time the fitting correctly so that it protects your tree from the winter moth;
Choose a product that fits your tree best;
Grease bands and tree barrier glues will give no protection against problems such as codling moth or plum moth which must be controlled separately.
