How do you stop grub moths from eating your apples on the tree?

Answer 1

Natural enemies, oils, proper cultivation, pruning, and sprays are ways to stop grub moths from eating apples on apple trees. Natural enemies such as nematodes and praying mantises eat grub moths while dormant and neem oils and pyrethrin (low toxicity non-organic) and pyrethrum (organic) sprays may be applied every 10 days. Irrigation and pruning schedules, nutrient levels, and soil pH need to be checked and possibly readjusted since stressed plants are more susceptible to pathogens and pests.

Answer 2

You need to keep the grass and plants under the trees short. You can use insecticidal soap on the tree. Some will paint the bottom of the tree to prevent borers from making holes in the trunk. Some use a mesh to discourage insects and birds from getting to the fruit.
