West Nile Virus (WNV) in Peel July 22 – July 28, 2018
The adult mosquito surveillance program started on June 17, 2018. Adult mosquitoes are collected weekly from mosquito traps at 33 fixed locations throughout the Region of Peel until late September. To date, 157 mosquito batches have been tested for WNV and three batches have tested positive, two in Brampton and one in Caledon. No human cases of WNV have been reported in Peel this season.
The larviciding program started on June 1, 2018 and will continue until September 30, 2018. Larviciding involves the application of environmentally friendly products to reduce mosquito larvae in stagnant water. The first round of roadside catch basin larviciding is completed and the second round is ongoing. The first round is indicated by a blue dot on the catch basin grate and the second round is indicated by an orange dot. It takes at least three weeks to complete a round of larviciding. There will be three rounds of roadside catch basin larviciding this year. Larviciding of catch basins in the green spaces of parks in Peel has been completed. The treatment of surface water sites on public lands is ongoing.
Reduce your risk of WNV by removing stagnant water on your property: • Empty or dispose of containers that can hold water, such as old tires, wheelbarrows, barrels, pails, toys and recycling bins • Turn over wading pools, remove water that collects on pool covers and make sure the pool’s pump is circulating. Protect yourself from being bitten by: • Avoiding areas with large numbers of mosquitoes • Wearing light-coloured clothing, including long sleeves, long pants, socks and a hat whenever you are outdoors (even when you are in your backyard), especially at dusk and at dawn • Use an insect repellent and apply it according to the manufacturer’s directions.
