First Aerial Spraying for Gypsy  Moth Completed May 31

GOOD NEWS!  Zimmer completed the first aerial spraying around Farlain Lake on Monday May 31!

We are into an outbreak level of the European Gypsy Moth as we are now in the third year of what is supposed to be a three year cycle. Over the winter we have helped property owners around the lake make private arrangements for aerial spraying by Zimmer Air since the municipality will not be spraying. Areas to be sprayed include the entire east side of the lake, clusters of properties on the west and southwest side, and a few on the south side. The eggs have hatched and we are now dealing with the early stage of the caterpillars which are floating in the air all around the lake and sticking to everything in sight.

All the latest updates from Zimmer re spraying can be found on their website under ‘Forest Pest Control‘.  You can check the Zimmer Air website weekly for updates on the spray schedule for the various areas of the province. Zimmer used 3 key parameters to determine when they could begin spraying.  One of those is “at least 90% of the caterpillars need to have hatched out”.  Zimmer posted signs around the lake on May 24 indicating the estimated range of dates for the two applications – May 26 to June 10.

A Reminder About the Spray

The product used is Bacillus Thuringiensis Kurstaki (BtK), a naturally occurring soil bacteria which attaches to the leaves and is then ingested by the caterpillars, causing them to stop eating, suffering death by starvation or by blood poisoning. It is a biologically friendly product, used all over the world, since the early/mid 80s, registered & approved for use by the Pest Management Regulatory Agency of Health Canada (PMRA) for residential use. It is not harmful to human, animal, bird or insect health and is considered low risk under the Ontario Pesticides Act. lt has no effect on bees, other insects, beneficial or otherwise, mosquitoes, birds, mammals, or aquatic life. lt is in fact Certified Organic.
