Gypsy Moth on the Rise again in 2021

Gypsy moth populations are on the rise again in Waterloo Region this year resulting in tree defoliation, especially oak, beech, birch and spruce in urban as well as forested areas. Gypsy moth caterpillar defoliation can result in tree stress and mortality. Background information can be found on the Pelham Niagara webpage.

Home control methods can be found by visiting the Pelham Niagara webpage and the Invasive Species Centre website.

The Grand River Conservation Authority is spraying two forested properties against gypsy moths in the Grand River Watershed. Visit Grand River Conservation Authority for additional information.
