Lambton Public Health says mosquito larviciding, at municipal catch basins, is set to get underway this week.
The process helps control mosquito larvae and reduces the incidence of West Nile virus.
We're being urged to keep an eye out for vehicles with a flashing yellow rooftop light, West Nile virus signs and “Makes Frequent Stops” caution sign.
Lambton Public Health said it isn't collecting dead birds for West Nile virus surveillance.
If you find a dead bird on your property, wear gloves or pick it up with a bag; then discard the bag and the bird into a garbage container. It can be disposed of with your regular garbage.
Residents are also encouraged to take precautions to prevent exposure to mosquitoes by eliminating breeding sites and standing water on their properties, and wearing insect repellent containing DEET.
Less than one per cent of people infected with the virus become seriously ill.
