Keeping the Legacy Alive

Slow the Spread

When not to be in infested areas if possible:                   


Mid-April until early August

This is when the crawlers are highly mobile!

Crawlers and eggs can be easily spread and cause new areas of adelgid infestation.

Remember that ten adults can produce up to 30 million new adelgid in two years!



Best practices when working in infested areas

How to help slow the spread of HWA. Keep in mind that HWA spreads very easily and can establish in new areas! By following this simple checklist, we can all do our part.


  • Use a lint roller to remove potential crawlers from clothing once you have left the forest stand
  • Beat and/or lint roll hats and coats
  • Avoid placing gear on or near hemlock trees
  • If possible, avoid visiting hemlock stands in uninfested areas for several days
  • Do not collect branch samples or specimens — photograph instead
  • Do not bring your pet into infested stands
  • Wearing light coloured clothing could assist with detecting and removing crawlers
  • Do not park your vehicle near or under hemlock trees
  • Launder all clothing prior to re-entering the field

Imposed wood movement restrictions in five southwestern Nova Scotia counties

December 19, 2017 – Ottawa – Canadian Food Inspection Agency

Following the recent detection of hemlock woolly adelgid in southwestern Nova Scotia, movement restrictions on regulated materials have been put in place for the counties of Digby, Queens, Shelburne, Yarmouth and Annapolis in the province of Nova Scotia.

In order to slow the spread of hemlock woolly adelgid and protect non-infested areas in Canada, the Canadian Food Inspection Agency (CFIA) restricts the movement of susceptible wood products from infested areas. As a result, wood products from these counties may be moved within the regulated area but may not be moved to non-infested areas.
