Aerial gypsy moth sprayings are planned near the Port Mann Bridge in 2020.
The treatment area is in Fraser Heights, next to Highway 1 and the South Fraser Perimeter Road, according to a release from the Ministry of Forests, Lands, Natural Resources Operations and Rural Development Wednesday (Dec. 18).
The sprayings would take place between April 15 and June 30, 2020.
The ministry is planning to aerially spray 241 hectares of residential and municipal parkland in north Surrey.
The area was hand sprayed in 2017 and 2018, and then aerially sprayed in 2019.
“It is now apparent that the treatments did not completely eradicate this infestation,” the release states.
Trapping and monitoring results over the past several years, according to the release, show “clear evidence” that gypsy moth populations are becoming established in the treatment areas.
“If left untreated, the invasive moth could spread to new areas of the province via vehicles, containers, rail and marine vessels.”
Members of the B.C. Gypsy Moth Technical Advisory Committee will be hosting an open house at Erma Stephenson Elementary school library (10929 160th St.) on Jan. 21, 2020 from 4:30 to 8:30 p.m.
The ministry says gypsy moths are an introduced pest species, and the caterpillars feed on tree leaves and can damage forests, farms and orchards.
