First Spotted Lanternfly Detected in Canada
The Canadian Food Inspection Agency confirmed the first detection of the invasive spotted lanternfly in Windsor, Ontario, on September 15, 2026. Movement restrictions are now in place as authorities urge the public to report sightings.
The Canadian Food Inspection Agency (CFIA) has confirmed the first detection of the invasive spotted lanternfly in Canada. The pest was found in Windsor, Ontario, on Sept. 15, 2026.
This discovery marks the arrival of the insect in Canada twelve years after its initial appearance in North America, where it was first found in Pennsylvania in 2014. The spotted lanternfly poses significant threats to agriculture, particularly the grape and wine industries, as well as forestry and horticulture. It feeds on the sap of more than 100 different plant species, including native hardwoods, fruit trees, and black walnut trees. The preferred host for the lanternfly is the invasive tree-of-heaven (Ailanthus altissima).
In response to the detection, movement restrictions have been implemented to prevent the spread of regulated materials. Colin Cassin, Executive Director of the Invasive Species Centre, noted that adult spotted lanternflies are most active in September and October during their mating and egg-laying season.
Authorities are urging the public to follow a 'spot it, snap it, catch it, report it' protocol to help contain the spread of this invasive species.
