San Jose scale are usually found ____________ of the apple tree.

• A. On leaves
• B. On the roots
• C. Beneath loose bark
• D. On fruit

Answer: (C)

Under bark crevices on the trunk and larger limbs—the space beneath loose bark—is where San Jose scale typically reside on apple trees. These armored scales attach to the bark and feed from the sap while the bark’s protection helps them survive cold and predators, making it a favored overwintering and early-feeding site. They’re not commonly found primarily on leaves, roots, or fruit, which is why this location is the best indicator to look for them. When managing, focus on crawlers in the spring and consider dormant-oil applications to smother scales sheltered under the bark.
