Stop the spread: destroy and report invasive species to keep them out of Canada

Pests travel when we do

Think of them as Canada's worst hitchhikers – they use our vehicles, trailers, soil, dirty footwear, furniture, camping equipment and more to spread from one region to another. Before you go somewhere, check for insect larvae, eggs, and adults like beetles, moths and others.

How invasive species threaten Canada

As worldwide trade and travel increase, the risk of spreading invasive species rises, potentially resulting in infestation which can harm or kill parts of our forests, agriculture and environment. Pests are often quick to adapt and spread, and usually don't have any natural predators in a new environment.

If pests do spread, they can:

Check the trees and gardens on your property:

  • The tree check form (from the Invasive Species Centre) provides a simple guide for what to look for

What the CFIA is doing about invasive species

As Canada's national plant protection organization, the CFIA

  • prevents the introduction of invasive species through import regulations
  • regulates the movement of invasive species within Canada
  • monitors invasive species that are not yet found in Canada
  • determines if an invasive species is now established

Be on high alert for these pests this summer and fall

The spotted lanternfly can destroy entire fruit crops very quickly, posing a huge threat to Canada's grape (wine), fruit tree and forestry industries. It is present in the United States near the Canadian border and spreading. Let's keep it out of Canada. It is not known to exist in Canada but was added to the regulated pest list in 2018 in an effort to prevent its introduction from infested areas in the United States and elsewhere.

What to do if you spot it: Always report it!

The emerald ash borer (EAB) has spread to parts of 5 provinces (New Brunswick, Nova Scotia, Quebec, Ontario and Manitoba) and has killed millions of ash trees across North America since being detected in July 2002. Firewood is the fastest way it spreads.

What to do if you spot it: Report it if you see it outside any of the 5 provinces listed, by contacting the CFIA online.

The spongy moth (Lymantria dispar dispar) is established in many areas east of the Manitoba–Ontario border. If you find it outside these regulated areas, including in Newfoundland and Labrador or in western Canada, report it by contacting the CFIA online. This pest could be a serious threat to Canada's economy. Look for this leaf-eating pest's eggs on firewood, vehicles, brick and items stored outdoors. Scrape off eggs and insects, soak them in hot soapy water, then scrap them in a zipped bag in the garbage.

What to do if you spot it: Destroy it – spot, scrape, soak

Don't let pests hitch a ride – learn their pathways

Pests can travel when we do:

  • Clean your shoes, tarps, trailers, RVs, gardening equipment and other outdoor materials before travelling in and out of regulated areas
  • Check for insect larvae, eggs, and adults like beetles and moths and remove them so they don't spread
  • Inspect and report sightings in Canada on vehicles, ships/boats, cargo and containers

Check the website of your provincial or territorial government, since invasive species may also be regulated by provincial or territorial authorities.
