Fruit Tree Leafrollers

Leafrollers and leaftiers are small caterpillars that feed on leaves, which they roll around themselves for protection. Both leafrollers and leaftiers are very similar in their habits and feeding, except that leafrollers roll leaves around themselves and leaftiers tie leaves together with silk thread. The caterpillar uses the leaf for protection against the weather, predators, and chemical sprays. Leafrollers can cause significant damage to fruit trees, vegetables, and ornamental trees, because they defoliate the tree and thereby place immense stress on the tree. Some leafrollers will also feed on the flowers and fruit of fruit trees and, if not controlled early, can prevent fruit production.

Recommended Steps to Control Fruit Tree Leafrollers

Spray the tree with Bug Buster Pyrethrin Insect Spray or Garden Insect Spray with Spinosad at the first signs of leafrollers or leaftiers. The sprays are much more effective if they are applied before the caterpillar is able to achieve protection inside the leaf. Repeat the spray, as needed, every seven to fourteen days.
