How to Eliminate or Control Spotted Lanternfly Adults:
If you find Spotted Lanternflies in a municipality where they are known to exist, you should try to kill them.
The most effective way to eliminate these insects is to disrupt their favorite food and hang‐out. In late summer and fall, Spotted Lanternflies prefer feeding on Ailanthus altissima, commonly known as the “Tree of Heaven.” They can be found feeding on other plants and trees, but Ailanthus altissima is their favorite host. Here’s an excellent resource to help you identify the tree: goo.gl/cNPQkS
If you have Ailanthus on your property: please consider reducing the number of Ailanthus trees, then treat remaining “trap trees” with insecticides. This is a longer‐lasting solution than simply spraying insects you see.
If you want to kill Spotted Lanternflies without controlling Ailanthus:
When there are only a few insects, you can kill spotted lanternflies by swatting or crushing them. For large populations, two kinds of insecticides are widely available that will kill Spotted Lanternfly adults.
Contact insecticides kill spotted lanternflies when the chemical contacts the insect directly. Systemic insecticides are absorbed by the tree and kill insects feeding on it. ALL insecticides must be used as directed on the label. Take the time to read the label carefully and follow the directions. This increases your safety, the safety of the environment, and the effectiveness of the insecticide.
Pennsylvania law requires that pesticide labels list the site where a pesticide (such as an insecticide) may be used. In Pennsylvania, insecticide labels do not have to specifically list the targeted insect. There are insecticides labeled for use on ornamental trees and around buildings. These products are legal to use on the sites listed in order to control Spotted Lanternflies in Pennsylvania.
Penn State Extension is currently testing to determine which insecticides are most effective in controlling adult spotted lanternflies. Preliminary results show insecticides with the active ingredients dinotefuran, imidacloprid, carbaryl, and bifenthrin are effective at controlling the spotted lanternfly. Neem oil and insecticidal soap provided some control, but results varied, and insects sometimes took several days to die.
Examples listed below are some of the available insecticide products containing the most effective ingredients studied (dinotefuran, imidacloprid, carbaryl, and bifenthrin).

Soon, lanternfly females will lay eggs. Lanternflies are great at hiding eggs. You can find masses on trees, cars, lawn chairs, underneath picnic tables or other obscure places. Those egg masses can survive the winter, so if you see a mass, and are able, try to scrape it off. Use anything to do it, like an old credit card or even a stick. PDA says to be sure to remove all seed-like black or brown eggs from underneath its protective wax coating. Then double bag and trash the eggs, or submerge them in hand sanitizer or alcohol.
Here’s an example of egg masses:
