However, they have been found to kill cultivated grapes, which can have devastating consequences for vineyard owners and regions that heavily rely on vineyards to create jobs and generate revenue. They have also killed the Ailanthu altissima, known as the tree of heaven, though this is classified as a noxious and invasive weed tree.
