The Town of Whitby and Region of Durham are committed to reducing stagnant water sources as a way to protect our community from West Nile Virus (WNV). West Nile Virus is a mosquito-borne illness that can be transmitted to humans by the bite of an infected mosquito.

Reducing mosquito populations helps reduce the spread of WNV and other infections spread by mosquitoes.

What can I do to reduce mosquito populations on my property?

You can reduce mosquito populations be eliminating stagnant water sources that act as a habitat and breeding ground for mosquitos. Here are a few tips for removing stagnant water sources:

• Remove unused objects, garbage or refuse that could collect stagnant water (e.g., tires, flowerpots, etc.)
• Turn over items such as wading pools, recycling boxes, wheelbarrows and boats when not in use
• Clean and chlorinate swimming pools, outdoor saunas and hot tubs and cover them when not in use
• Drain of water that collects on pool covers, window boxes, flower pots, etc. at least once a week
• Change the water in wading pools, bird baths and pet water dishes at least once a week
• Aerate ornamental ponds, or stock self-contained ponds with mosquito-eating fish (e.g., goldfish, koi, etc.)
• Cover rainwater barrels with a fine mesh or screen
• Don't wash grass clippings or leaves down roadside catch basins
• Turn compost over on a regular basis
• Do regular landscape maintenance of weeds, tall grasses and shrubs
• Do regular maintenance of roof gutters to prevent clogging
• Ensure that doors and windows have tight fitting screens and are in good repair

You can also help by reminding your neighbours to eliminate mosquito-breeding sites on their property.

Why should I be concerned about stagnant water?

It only takes four days for stagnant water to become a breeding site for mosquitos. By removing stagnant water sources, we are making it difficult for mosquitos to reproduce and grow their populations.
