AERIAL SPRAY NOTIFICATION – Gypsy Moth Control Program

An aerial spray for the control of Gypsy Moths has been scheduled for Tuesday, May 18th, 2021. Zimmer Air Services Inc. is scheduled to administer the aerial spray by helicopter between 5:30 a.m. – 9:00 a.m. Residents can expect high audible levels during the spray.

Weather is the primary factor when scheduling spray dates. If the weather is not cooperative on the scheduled date, the spray will commence the next available day that weather parameters are within approved limits. A rescheduling notification will be sent if applicable.

Members of the public are unlikely to experience any health effects and no special precautions are necessary or required. Individuals who have concerns should take reasonable precautions to avoid exposure during an application period. While no special precautions need to be taken, the following measures may be considered by residents living in treatment areas:

  • Whenever possible, remain indoors for 30 minutes after spraying to allow for the droplets to deposit onto the tree leaves.
  • Bringing laundry, toys and pets indoors before spraying begins.
  • 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).
  • Covering lawn furniture, outdoor tables, pools, BBQs, play equipment and sandboxes and/or rinsing them off with water after spraying is finished.
  • Minimize opening and closing windows and doors during the spraying.
  • Shutting off the heating/cooling vents or selecting the recirculate setting.
  • Contacting your family physician if you are concerned that a personal medical condition may be aggravated by the spraying.

The second spray application will occur within 5-10 days of the first spray, weather depending. Another notification will be sent out in advance.

The aerial spray program will apply the biological pesticide Foray 48B Biological Insecticide Aqueous Suspension. The active ingredient in the spray is Bacillus thuringiensis v. kurstaki (Btk), Registration No.24977 under the Pest Control Products Act (Canada).

Btk is a bacterium found naturally in soils, and has been used for some 30 years successfully world wide as a biological pest control agent. Btk has been used on millions of acres of wooded areas and agricultural crops in many countries worldwide. More information on this biological pest confirm agent is available on the Government of Canada’s website.

Homeowners within the spray areas have been sent a letter.
