Frass is insect debris (waste or poop). Two insects can be identified on blueberries by the frass they leave behind. Click on the links below for information about what damage these insects can do to blueberries and how these insects can be managed.
Blueberry tip borer causes damage by feeding internally. This feeding causes the stems to wilt and the leaves to dry from the tips. Pruning infested shoots can help suppress populations.
Cranberry fruitworm is one of the most serious pests of blueberries in the eastern United States. Some fields have suffered 50 percent to 70 percent fruit loss. Infested berries may be harvested and packaged without detection, resulting in consumers finding larvae in packaged berries.
