Mosquito Control, June 10

An aerial mosquito control treatment of Brae Island will take place Thursday, June 10 between 3:30 and 5:30pm. Hand-treatment will also take place at select additional sites.

Bti, short for Bacillus thuringiensis subspecies israelensis, is an environmentally-friendly pellet larvicide that is not toxic to humans and is 80-90% effective in reducing mosquito populations at the larval stage of life. Morrow BioScience, the Township’s nuisance mosquito control contractor, will carry out this treatment.

Do your part

Fight the bite by keeping your property free of standing water (drain birdbaths, dispose of old tires, keep drains, eavestroughs, and basins dry, etc.); take extra care at dusk and dawn (when mosquitoes are most active); wear loose-ftting, light-coloured clothing; and use mosquito repellent.
