According to scientists at Penn State University, spotted lanternflies do not typically kill the trees and plants they feed on, but they can cause branches and segments to die off. 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.

Rock salt or Epsom salt can damage and kill tree roots over several weeks and can even assist in removing the tree's stump. However, you need to drill holes or cut into the stump and surface tree roots to inject them properly with the salt. Repeat the process every two weeks until the roots visibly rot away.

If the roots are still alive, the dead tree will usually try to put out new shoots. That doesn’t mean the tree will survive or that the dead parts of a tree will come back to life. If parts of the tree have died and turned gray or rotten, nothing will bring them back to life and they need to be safely removed.
