Gypsy Moths – Removing Egg Masses

As the trees are beginning to bud, we urge residents to please check their trees for Gypsy Moth egg masses and destroy them.

Gypsy moths are invasive pests that feed on the leaves of trees. Controlling the spread of gypsy moths is important to help protect Markham’s urban forest.

Egg masses can be found on tree trunks, branches, buildings, and objects around the house. One egg mass contains about 300 eggs. By destroying them you will significantly reduce the number of caterpillars that emerge this year.

To remove and destroy the egg masses, gently scrape them off the bark into soapy water.
