Medlar pests — FAQ
What is eating my medlar?
Medlar is one of the most pest-resistant tree fruits available to UK and US gardeners. The most likely visitors are aphids on new spring growth and codling moth larvae inside fruit. Brown rot fungus is a bigger threat than insects. Wasps and birds can damage softening fruit during the bletting stage. No routine spraying programme is usually needed.
