The European Gypsy Moth is a pest found throughout North America. The caterpillar eats the leaves of trees which may damage the overall health of the tree. Gypsy Moth populations have been in the City of Mississauga for many decades.
The City is now inspecting and choosing City-owned Oak trees to do Integrated Pest Management (IPM) to help manage the Gypsy Moth population in the City. IPM combines biological, physical, and chemical tools in a way that minimizes risks to health and the environment. IPM does not eradicate a particular pest entirely. Rather, it keeps pest population at a manageable level so they do not cause significant damage to trees and the tree canopy
Things you can do on your own trees:
- Install burlap wraps around tree trunks, and collect and destroying caterpillars (May-September)
- Scraping off and destroying egg masses (until mid- May; August - April)
- Using pheromone traps to capture and confuse male moths (June to August)
These steps have proven very effective in controlling Gypsy Moth. A few weeks ago, Forestry held an open house for Ward 2 residents to provide them information on how to treat Gypsy Moth. All attendees received a free moth trap. To learn more about Gypsy Moth, visit Mississauga.ca/urbanforestry.
