The City of Mississauga will be conducting an aerial spray in your area to manage high population levels of an invasive insect pest Lymantria dispar dispar (LDD), formerly referred to as Gypsy Moth sometime between May 15th and June 12th. If left unmanaged, these elevated population levels will lead to severe loss of leaves in the City’s urban forest and cause trees to become more susceptible to disease and weather events like drought or ice storms.

You are receiving this email because a portion of the aerial spray occurs within your resident’s association area (Erindale Village Association).

We kindly ask that you share the attached information with members of your association. This same post card will be mailed to residents in affected areas in the coming week.

We would also encourage your members to sign up for information and alerts via our project website at and review the ‘how to prepare’ information contained on our website and also copied below. 

How to prepare

Peel Public Health recommends that the public stay indoors during the spray and for 30 minutes following to allow the droplets to settle. Infrequently, there may be some residents who are more sensitive and may experience skin, eye or respiratory irritation.

Residents with health-related questions can call the Peel Public Health at 905-799-7700 or speak to their family physician.

Individuals who have concerns should take reasonable precautions to avoid exposure during the spray which may include:

·       closing windows

·       turning off fans or air conditioners or setting them to the recirculate mode

·       bringing in laundry and toys

·       keeping pets indoors

·       covering pools, BBQs, play equipment, lawn furniture, sandboxes and automobiles

After the spray, residents are encouraged to:

·       wash/rinse pool covers, BBQs, play equipment, lawn furniture and automobiles, with water

·       Practice good personal and food hygiene (e.g. hand washing after outdoor activities, especially after gardening; leaving outdoor shoes at the door; washing all fruits and vegetables before eating or cooking)

·       Washing your pet’s paws before entering the home

·       Leave outdoor shoes at the door

The City is committed to ensuring all possible steps are taken to keep residents healthy and safe and are working closely with several partners including Peel Public Health and Peel Regional Police to ensure the safety, security and health of residents and the environment.
