The department's recommended technique for controlling spotted
lanternfly is host tree removal and trap tree establishment.
Spotted Lanternfly Property Management Tips
Knowing that spotted lanternfly has to feed
on Tree of Heaven allows for strategic targeting of spotted lanternfly. To do this, kill about 90% of tree heaven on
your property. Simply cutting down Tree
of Heaven is not sufficient to kill it; you must apply herbicide to the stump. Trees selected to be killed should be females
(the seed producing trees). Killing of
Tree of Heaven can be done year round.
Starting in May, treat the remaining 10% of tree of heaven on your
property with a systemic insecticide, PDA is using products containing
Dinotefuran. When Spotted Lanternfly starts
to congregate to Tree of Heaven in late July, they will feed on your trap trees
and are killed.
In instances where host tree removal and trap establishment
isn’t feasible, homeowners can scrape egg masses. Egg masses are live and viable from about
October through July. Volunteers can
scrape them off of trees or smooth surfaces, double bag them and throw them in
the garbage, or place the eggs in alcohol or hand sanitizer to kill them. See instructional video at the bottom of this page.
Please let us know of your efforts by
recording the number of eggs masses you
scraped and/or destroyed: Egg Scraping Survey (instructions for entering scrape data).
Total number of eggs scraped as 5/2/2019: 2,336,740.
Homeowner cans also choose to band their trees. Existing literature demonstrates that brown
sticky tree bands are an effective, environmentally friendly way to catch
spotted lanternfly nymphs. Through
Federal Farm Bill funding, a limited number of bands have been made available
for owners of confirmed infested properties.
People interested in banding
their trees can attend training sessions in early spring. At the conclusion of the training session,
homeowners are given a kit that contains all of the material needed for banding

Number of Spotted Lanternfly killed by tree bands: 1,007,200
Treating a Property without Tree of Heaven
There are cases where there may not be Tree of Heaven on your
property but you are finding Spotted Lanternfly. In Pennsylvania, application of insecticide
is site specific, meaning you can use insecticides labeled for use on
