Protecting Apple Trees from Bark-Feeding Insects

Organic Defense for Apple Tree Bark

A large bee chewing on apple tree bark signals a potential pest issue—often carpenter bees or beetles. Quick action with organic insecticides can save the tree.

Recommended Treatments

Pyrethrum – Natural extract from chrysanthemums, fast-acting against a broad range of insects.
Rotenone – Plant-based, effective on bark-feeding pests. Both are organic and widely available.

Application

Spray the trunk and affected branches thoroughly, following label rates. Repeat as needed, especially after rain.

Monitoring

Inspect the tree weekly for new activity. Early intervention prevents extensive damage and preserves fruit production.
