Do you know what spotted lanternfly looks like?
Spotted lanternfly (SLF) is an invasive sap-feeding planthopper that has the potential to be a nuisance pest in the landscape with the potential to harm the agriculture and forestry sectors.
It is not yet established in Ontario, but now is the time to inspect trees and shrubs for small black/white spotted nymphs that are pretty jumpy when disturbed. In mid- to late-July and August the late-stage nymph will become larger and change to red with white and black markings
While out in the field and on jobsites this year, landscape and horticulture professionals are asked to “‘Adopt a Spot” and regularly inspect preferred plants such as wild grapevines, maples, black walnut trees and tree of heaven throughout the season.
Any potential sightings of spotted lanternfly should be reported to the Canadian Food Inspection Agency (CFIA) using the Report Plant Pests button at inspection.canada.ca/pests.
