![]() This will minimize the downsides of a pesticide-first strategy, which include detrimental effects on humans, pets, livestock, and other non-target organisms, as well as the development of pesticide resistance (and resulting loss of effectiveness) in the target pest. The goal is to develop a holistic integrated pest management (IPM) strategy to combat spotted lanternfly, incorporating a variety of research-driven techniques to supplement the use of pesticides wherever possible. Pennsylvania agriculture experienced losses of entire grapevine plants in some vineyards, and their economists estimate a potential combined annual loss to their state of $324 million and 1,665 jobs.īecause SLF is a significant agricultural pest, research is underway even now, as Cornell investigates biological control and other management options. As the pest has begun to spread to neighboring states, knowledge and experience from Pennsylvania’s SLF researchers and specialists has been benefiting New York. While SLF is native to Asia, it was first found in the U.S. SLF’s excrement-a sappy liquid called honeydew-makes things sticky and becomes a breeding ground for sooty mold, an annoying black fungal growth. Nymphal and adult SLF have piercing-sucking mouthparts that drill into plant phloem. For most New Yorkers, it will be no more than a nuisance pest. SLF does not bite or sting and is not a threat to people, pets, or livestock. SLF is not a fly, but rather a large planthopper. With New York State’s important Finger Lakes grape-growing region and wine industries so close to Ithaca, state agencies and researchers are particularly concerned about this pest’s impact in the region. However, SLF also feeds on many other trees and plants, which, unfortunately, includes grapevines. They were found on their favorite host plant, another invasive species, tree of heaven ( Ailanthus altissima).

Local residents should also report new sightings so that early action can be taken to prevent or slow down a potential infestation. If you find spotted lanternflies around your home or neighborhood, the official instructions are to kill them immediately in order to help stop them from spreading. Getting rid of them requires cooperation of everyone. In the summer and fall, these pests can be found in huge swarms around trees, poles, sidewalks, houses, and buildings. Once they become established in an area, spotted lanternflies spread quickly and are difficult to control. While spotted lanternflies are not directly harmful or dangerous to humans, you should be very concerned if you see them. ![]()
