Story summary

The Canadian Food Inspection Agency (CFIA) confirmed the first detection of the invasive spotted lanternfly in Windsor, Ontario on September 15, 2023, marking its arrival in Canada. This insect, native to southeast Asia, has spread across 18 US states since it was first detected there in Pennsylvania in 2014. The spotted lanternfly feeds on over 100 species of trees and plants, significantly impacting grapevines, which could threaten Canada's wine industry if the infestation spreads to vineyards. The CFIA is conducting surveillance around Windsor to assess the extent of the infestation and plan future actions to mitigate its spread.
