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.

To learn more about the hemlock woolly adelgid, visit the species profile.

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

 

Don't let invasives ruin your garden!

Try planting these and other native species instead! They look great, and they don't threaten Ontario's biodiversity. For more info on what plants are good for your garden check out these Grow Me Instead guides.
