Mosquitoes

Our Nuisance Mosquito Control Program is described through the Pest Management Plan [PDF - 3 MB] and has been authorized through the Ministry of Environment and Climate Change Strategy under the Integrated Pest Management Act.

We work closely with Morrow Bioscience to monitor, map and treat known breeding sites of nuisance mosquitoes. View a map of the treatment area [PDF - 3 MB]

Our program targets the most common nuisance mosquitoes found in the Fraser Valley – floodwater mosquitoes, which hatch when river levels rise during freshet. The program focusses on controlling these mosquitoes in their larval stage before they emerge from the water as adults.

Throughout the spring and summer, our field technicians actively monitor larval development across the region. When the larvae reach the right stage and density at a site, the area is treated by hand or by helicopter using a bacterial larvacide which kills the mosquitoes without affecting other creatures in the water. The FVRD does not conduct fogging or spraying for adult mosquitoes. Please visit the FAQ page if you have more questions about the program. 

As you can see in the before and after videos below, our mosquito control program quite effective. The site was monitored on June 15, 2016, and treated on June 17, 2016.
