The findings of the Canadian Food Inspection Agency (CFIA) are an important reminder that shipments (both plant and non-plant products) and transport vehicles and vessels are a high-risk pathway of spread for this hitchhiking invasive insect. Observations of spotted lanternfly (SLF) in Canada are posted on the CFIA’s website. There are no confirmed established populations in Canada at this time.

What can you do?

1. Train your vineyard teams on the life stages of SLF. For May-July, keep an eye out for egg masses laid on flat surfaces and the early-stage nymphs. Informational resources are available online through the Invasive Species Centre and OMAFA. Grape Growers of Ontario has info cards and posters in English available at the Board Office. OFVC presentations on preparing for SLF are posted HERE.

    

    

2. Familiarize yourself with the States that have established populations of the SLF, listed in the Current Status dropdown on the USDA’s SLF webpage.

    

3. Immediately inspect all shipments you receive from an infested State for all SLF life stages (egg masses, nymphs and adults).

    

4. If you are travelling back from or have travelled through an infested State, check your car, camper, trailer, RV, and supplies before making the return trip.

    

    

5. Spot it? Snap it, catch it and report it. If you think you have found the SLF or its egg masses:
   1. Take a photo or video
   2. Catch the insect or scrape the egg masses, and put it into a sealable container
   3. Report it on CFIA’s SLF webpage.
