Hello Kathleen,

Fortunately, with several years of observations and studies having taken place since this insect first arrived in our area, Spotted Lanternfly (SLF) is not known to cause any serious damage to home garden plants. Because of this, no treatment is necessary. Additionally, no insecticide is specific to SLF where it will not pose some risk of harm to pollinators, beneficial insects, or other wildlife that come into contact with its residues. If the tree in question is a Tree of Heaven, then its removal is recommended because it's an invasive species, but otherwise the tree should be fine without intervention.
