A Message from the TBA on Gypsy Moths: 

This summer saw a horrible infestation of Gypsy Moths which decimated many trees.  According to the Ontario Government, the defoliation caused by gypsy moths in Ontario increased from 47,203 hectares in 2019 to 586,385 hectares in 2020.  In the spring of 2021, the Gypsy Moth larvae will emerge from the egg masses in the trees.  Consequently, the next months will be the time to take action.  More information is available HERE.

At last summer’s Annual General Meeting, a motion passed for the association to provide information to all of our members regarding safe proactive measures that can and should be taken.  The Thunder Beach Association encourages everyone to sign up prior to March 1, 2021 deadline as per the details that follow. 

Health Canada has approved an organic pesticide, which is naturally occurring in soil bacteria, called Bacillus thuringiensis kurstaki (“Btk”).  It has been used by many communities including the Grand River Conservation Authority.  According to the Grand River Conservation Authority website, it has been used for over 30 years and has very little impact on other insects, birds or mammals.  

Zimmer Air has set up numerous spraying programs of Btk for municipalities, private landowners, and associations.  We encourage everyone to review the available information and sign-up in an effort to save our trees from this invasive species.  If last summer is any guide to us, the risks of doing nothing are too great.  

Zimmer Air will only agree to spray your property if your neighbours either participate or sign the waiver available here.  Accordingly, these measures require a community response and will be optimally effective if everyone signs-up. If you are an owner of multiple adjacent/neighboring lots, only one contract fee will apply with additional fees if the lots exceed one acre. All applications and waivers must be signed, add THUNDER BEACH above CONTRACT FOR SERVICES or add THUNDER BEACH above SPRAY (OBJECTION) WAIVER, include required map and submit to before the March 1st deadline.  

Special thanks to Barb Reidl and to the team at FOTTSA for their ongoing work and assistance on this important issue.

The Thunder Beach Association is providing this for information purposes based on our understanding of the problem and proposed solution.  The decision to conduct spraying is up to each property owner.
