Be aware of hemlock woolly adelgid this spring!

Hemlock woolly adelgid (HWA) is native to Asia, and was first detected in eastern North America in the 1950’s. This invader attacks native hemlock species, which are commonly found in Ontario forests and urban spaces.

Look for white, cotton-like or woolly masses forming on the base of hemlock needles.

If you see signs and symptoms of HWA in Ontario, please report the sighting to the CFIA or EDDMapS Ontario.
