European Gypsy Moth Aerial Spray Helicopter (City of Toronto)

The City of Toronto is implementing the first round of its aerial spray program later this week.

The spray is for tree-damaging European Gypsy Moths and will protect the canopy and vulnerable trees from infestation.

According to the City, gypsy moths are an invasive insect whose caterpillars feed primarily on the leaves of oak and other trees species. The severe leaf loss created by these insects can make trees weak and susceptible to diseases and weather fluctuations. Untreated, those pressures can result in the loss of public and private trees.

During the aerial spray, the City says one twin-engine helicopter with an ultra-low-volume spray system will fly about 15 to 30 metres above the tree canopy to apply a biological insecticide. The product must be applied directly to tree foliage, as Gypsy Moth caterpillars must feed on the treated leaves for the insecticide to be effective.

This year, the aerial spray will target a “high risk” area in Ward 2 – Etobicoke Centre, as it contains a “dense, mature, and large canopied oak tree community.”

Residents can expect the first round of aerial spraying on Thursday, May 28 between 5:30 and 7:30 am, weather permitting. Should weather conditions be less than optimal, the City will reschedule the initial aerial spray.

According to the city, the spray area is located south of Eglinton Avenue West and west of Kipling Avenue, between Warrender Avenue and Princess Margaret Boulevard. A map of the designated spray area is available online.

A second round will be applied within days, but specific dates have yet to be determined.

“As a result, specific spray dates are confirmed 48 hours in advance and can be cancelled if weather conditions change.”

The City of Toronto also says the insecticide they are using is called Foray 48B Biological Insecticide Aqueous Suspension, of which Bacillus thuringiensis subspecies kurstaki is the active ingredient (identified under Pest Control Products Act Registration Number: 24977 class 11).

The pesticide does not affect adult moths, butterflies, bees, fish, birds or mammals. This is a biological control made from a naturally occurring bacterium found on dead or decaying matter in the soil that poses minimal risk to human health and is approved by Health Canada for urban aerial use.

SANTA PICIt’s that time of year again when Santa is going to come for a visit to Devonshire Mall in Windsor, Ontario. Santa loves arriving by helicopter because it is much quicker than his sled and reindeer. He needs to visit and get back to the North Pole quickly with the lists of games and toys you have told him you would like for Christmas. Have you been naughty or nice?

Come and join in the fun! See you there!









Another successful Helicopter Rides event Thanksgiving weekend at the Brigden Fair! It is truly remarkable how good weather usually coincides with the Brigden Fall Fair. Although Saturday was a rather windy day and we had to modify our flights, overall the week-end was a huge success for all involved. Another marriage proposal happened again this year! We appreciate the opportunity to be a part of this fall fair classic and look forward to our continued participation in future years.
