Residents of Cloverdale and parts of Surrey and Delta are being reminded that the first round of aerial spraying to combat the Gypsy moth began today.
Wednesday is the first of four consecutive days of spraying planned (April 15 to 18) for the target area – more than 4,500 hectares around 64 Avenue and 176 Street in Surrey, and 204 hectares between Highways 10, 99 and 91 in Delta.
Spraying will continue Thursday, Friday and Saturday, between 5:20 and 7:30 a.m., weather permitting.
People living immediately next to the treatment area may hear a low-flying helicopter as turns around and re-aligns.
The area is being treated with Foray 48B to eradicate the introduced moth.
Organic farms treated with the product will not lose their certification, the Ministry of Forests said Tuesday in an announcement.
Poor weather or wind may force ministry officials to postpone the treatments to the next suitable morning.
There are two more sets of treatments to take place. Due to the early spring, staff hope to complete all spraying by mid-May.
The targeted areas include most of Cloverdale, from the Langley border between Highway 10 and 80 Avenue, and extending as far west as 144 Street, taking in Sullivan and eastern Panorama Ridge.
An additional 26-hectare ground spray will also be done on a rural property due south of the 172 Street and 56 Avenue intersection.
Foray 48B contains the bacteria Btk and kills caterpillars after they ingest it but doesn’t harm humans, mammals, birds, fish, plants, reptiles, amphibians or other insects.
It’s approved for use on organic farms.
The moth is an introduced pest species. The caterpillars feast on tree leaves and can damage forests, farms, and orchards.
Nearly 200 male European gypsy moths were caught in pheromone traps last summer in Cloverdale on trees along 64 Avenue.
If left untreated, the destructive moth could spread to new areas of the province by hitching a ride on vehicles, containers, trains, port terminals and B.C. Ferries.
