Moving across Canada: Don't take the LDD moth with you

The LDD moth (Lymantria dispar dispar) is an invasive pest in Ontario, Quebec and the Maritimes. It isn't present in western Canada or in Newfoundland and Labrador.

It can defoliate trees in our campgrounds, forests and neighbourhoods.

Things stored outside, including campers, trailers, outdoor furniture and play equipment, could transport the LDD moth. Egg masses, larvae, caterpillars and moths must be removed before you move these items to an area where the LDD moth isn't present.

Protect your new neighbourhood. Make sure the LDD moth doesn't hitch a ride with you. Canada's trees depend on you.

Check the map of regulated areas for LDD moth to find out if the risk of transporting this pest applies to you.

Check your postal code

If you're moving from a postal code starting with B to N (the Maritimes, Quebec and southern Ontario) to a postal code starting with A or R to Y (Newfoundland and Labrador, western Canada or the Territories), the LDD moth could be moving with you on your vehicle or your outdoor belongings.

If you are moving from a postal code starting with P (northern Ontario), please also look for this moth, especially if you're moving from:

You should also be on the lookout and apply the same measures if you are going on a camping trip to western Canada, the Territories or Newfoundland and Labrador in your RV, tent or trailer.
