Join your fellow community scientists with the Wisconsin First Detector Network (WIFDN) as we use the invasive tree-of-heaven, Ailanthus altissima, to monitor for spotted lanternfly (SLF).
What is tree-of-heaven?
Tree-of-heaven poses a threat to our ecology in Wisconsin as it grows rapidly, spreads clonally underground, and can quickly smother native vegetation. This printable factsheet offers more information about tree-of-heaven, including identification strategies.
What is spotted lanternfly
Spotted lanternfly is from the same part of the world as tree-of-heaven and prefers it as a host for sap-sucking and laying eggs. However, spotted lanternfly readily switches hosts to native and ornamental plants and poses significant risk to the orchard industry.
Is tree-of-heaven in Wisconsin?
WIFDN has created a map that shows the locations of every reported tree-of-heaven in Wisconsin, hosted by Google Maps. Visits to these tree-of-heaven sites can be submitted as “re-visits” at EDDMaPS.org. Use the object ID# to find and update the existing report. As locations are checked, we will change the color of the dot on the map so we can see what has already been visited.
Alternatively, people can submit new tree-of-heaven reports by filling out this form. Please remember to include photos of your tree-of-heaven and/or spotted lanternfly sighting!
When is the best time to look for spotted lanternfly?
August and September are ideal months to look for spotted lanternfy, as the insect is in an easily recognizable (adult) phase of their life cycle.

How do I report sightings of tree-of-heaven or spotted lanternfly?
Presence/absence of spotted lanternfly (SLF) on tree-of-heaven (TOH) sites can be recorded in two ways:
- Go to www.EDDMapS.org
- Search for TOH site by entering object ID# from the google map in the “maps” tab
- Click revisit on the top of the reporting form
- Click if TOH is present or eradicated and add pictures
- Enter “TOH for SLF” in the comments at the bottom and mention if SLF is present
- Go to our Google Form and fill out requested information:
- Date of visit
- TOH site object ID# from the Google Map
- TOH present or absent
- SLF present or absent.
- Nearest City/Town/Village
