PEST ALERT: Spotted Lanternfly Detected in Ontario

Published date: September 23, 2026

The Canadian Food Inspection Agency (CFIA) has confirmed the first detection of spotted lanternfly (Lycorma delicatula) in Canada, in Windsor, Ontario. 

Spotted lanternfly (SLF) is an invasive insect that feeds on more than 100 plant species, posing a serious threat to PEI’s wine, nursery, fruit and forest industries. Grapevines are particularly vulnerable to significant feeding injury, but SLF can also affect many types of trees and plants.

What to look for

  • Adults: approximately 2.5 cm long, with distinctive spotted wings
  • Nymphs: black with white spots when young, developing red coloration as they mature
  • Egg masses: grey/brown, mud-like masses found on trees, plants and many outdoor surfaces

Help prevent the spread

Spotted lanternfly can be moved accidentally on vehicles, outdoor equipment, trailers, firewood, pallets, plant material and other items. If travelling from an area where SLF has been detected, inspect vehicles, equipment and outdoor items before moving them.

If you suspect spotted lanternfly:

SPOT IT → SNAP IT → REPORT IT

Take a clear photo and report the suspected pest to the CFIA as soon as possible. If safely possible, collect a specimen for identification. Do not move live specimens to another location. 

Early detection and reporting are critical to supporting surveillance and preventing the spread of this invasive pest.
