Grease bands on fruit trees
A grease band applied to the trunk of a fruit tree is a simple way to reduce pest damage caused by winter moths. The wingless females climb the tree from late autumn and lay eggs in the branches. Caterpillars hatch in spring and cause damage to new leaves, shoots and blossom. The sticky grease bands trap female moths as they climb the trunk. Grease bands don’t, however, catch codling moths, whose caterpillars tunnel into fruits during summer.
