Poppy - we need to understand the life cycle of the codling moth to explain the measures I mentioned.
Full instructions come with those pheromone traps...but basically the sticky pads are marked into squares to help assess the number of moths in the infestation, enabling us to be able to calculate to amount & frequency of spray required.
Winter tar oil wash is applied when the trees are totally dormant and is intended to destroy the eggs and larvae of the moth hiding in the bark.
Grease bands are intended to prevent females, which, after emerging from the pupal or chrysalis stage in the soil, climbing the tree to mate and lay their eggs.
