Open house on gypsy moth aerial spray program in Lake Cowichan

LAKE COWICHAN – The public is invited to attend a community open house and participate in a discussion about the 2020 gypsy moth aerial spray treatment program in Lake Cowichan.

The meeting will be held on Tuesday, Jan. 28, 2020, from 4:30 p.m. to 8 p.m. at Lake Cowichan school gymnasium on 190 S. Shore Rd.

Members of the B.C. gypsy moth technical advisory committee will be joined by representatives from the Ministry of Environment and Climate Change Strategy, Ministry of Agriculture and Canadian Food Inspection Agency, as well as other experts, to answer questions and provide information about the 2019 trapping season and the planned 2020 aerial spray program.

The 2019 trapping data shows that a population of moths in Lake Cowichan has persisted for at least two years and appears to be growing. The gypsy moth technical advisory committee has determined that it is necessary to treat 231 hectares of residential and municipal land to eradicate gypsy moth.

The planned treatment will use aircraft to apply Bacillus thuringiensis var kurstaki (Btk), a biological insecticide that occurs naturally in soil and is commonly used in organic agriculture. Btk is effective at treating gypsy moth. It affects only caterpillars that eat sprayed leaves and has a proven safety record around humans. Livestock, pets, birds, fish, spiders, bees, ladybugs and amphibians are not impacted by Btk.

The gypsy moth is an introduced pest species. The caterpillars feed on tree leaves and can damage forests, farms and orchards. Large gypsy moth populations have defoliated sections of forests and residential areas in Ontario and the eastern United States in recent years.
