AERIAL SPRAY NOTIFICATION – Gypsy Moth Control Program

UPDATE (May 28th, 2021): Zimmer Air Services Inc. was unable to complete their second aerial spray this week due to weather conditions. Weather permitting, the spray program is scheduled to resume Sunday morning (May 30th) between 5:00 a.m. and 11:00 a.m.


The second aerial spray application has been scheduled for Tuesday, May 25th. As with the first spray, Zimmer Air Services is scheduled to administer the aerial spray between 5:00 a.m. to 9:00 a.m. using helicopter.

Should weather not permit spraying that day, the program will commence the next available day that weather parameters are within approved limits. A rescheduling notification will be sent if applicable.


Although the 2021 Aerial Spray Program by Zimmer Air Services Inc. has been organized privately, the Municipality of Lambton Shores has been asked by the Ministry of the Environment, Conservation and Parks to issue the Public Notice of Pesticide Use, including notification letters to property owners in the spray areas, newspaper, roadside, and website messaging.
