The Perth District Health Unit’s annual West Nile virus surveillance has begun. The unit uses catch basin larviciding to help control the mosquito population.
They also trap and test the insects to track the virus in Perth County and reduce the risk to humans. So far no mosquitoes caught in the county this year have tested positive for the virus.
In the meantime there are things you can do the help cut down the risk of West Nile.
You should also empty standing water on your property at least once a week, use bug spray with DEET or Icaridin, and wear light-coloured long sleeves and pants.
