SURREY – Sixty-two hectares of residential and municipal park land in North Surrey are planned for an aerial spray beginning in early May until June 30, 2019. The aerial spraying aims to eradicate a growing population of gypsy moths and minimize the risks they pose to forests, farms, orchards and trees. The Ministry of Forests, Lands, Natural Resource Operations and Rural Development has been issued a pesticide-use permit to aerial spray and is planning up to four applications of Foray 48B over the two-month time period to control the moth. Foray 48B is used in organic farming and contains bacillus thuringiensis var kurstaki (Btk). Btk has been approved for the control of gypsy moth larvae in Canada since 1961. Btk does not harm humans, mammals, birds, fish, plants, reptiles, amphibians, bees or other insects and only affects caterpillars after they have ingested it.
