The City of Mississauga is launching its annual Integrated Pest Management program to help reduce the number of gypsy moth caterpillars in Mississauga. This invasive insect causes tree destruction by feeding on the leaves of oak and other deciduous trees. After repeated defoliation, trees may die or become so weakened that they are vulnerable to secondary infestations.
“As a City, we have made many critical investments to protect and preserve our tree canopy throughout Mississauga to benefit the entire community,” said Mayor Bonnie Crombie. “Trees play a vital role in our fight against climate change, while providing endless benefits like cleaning the air of pollutants, providing habitats for wildlife, helping to make our city beautiful and adding charm to our neighbourhoods. Mississauga has been faced with trying to eradicate invasive species and limit their damage to our tree canopy and we have been successful with our mitigation management of the Asian Longhorned Beetle.”
The City will focus its efforts on areas in Mississauga that have higher populations of gypsy moth egg masses. Three strategies will be implemented:
“Gypsy moth caterpillars aren’t new to Mississauga. They have been around for more than a decade. They have caused a lot of damage to the City’s already vulnerable hardwood trees. Through our comprehensive Integrated Pest Management program, we have learned how to control their populations by using different pest management strategies,” said Jodi Robillos, Director, Parks, Forestry and Environment. “We have seen the destruction gypsy moths can cause to our urban forest and many of our diverse tree species. The preservation of our urban forest canopy is critical because trees are an important component of a healthy ecosystem. The goal of the gypsy moth program is to control the population and preserve the health of Mississauga’s urban forest canopy. This is why our Integrated Pest Management program is important and why our continued efforts matter.”
New this year, the City is launching an Interactive Treatment Map and a Reporting Form. The Interactive Treatment Map will display the publicly-owned trees along specific streets and in certain parks proposed for treatment. The Reporting Form will allow residents to report gypsy moth observations by inputting details including quantities and life stage observed and sharing photos.
Over the next few weeks, City staff and contractors will be applying pest management strategies in certain areas around the city. Residents are reminded to maintain a physical distance of at least 2 metres (or 6 feet) from staff.
