I've never been clear on what exactly the mitigation is for WNV. It's not like you can prevent mosquitoes biting you. Often you don't even know it's happening. What exactly are you supposed to do?
The article says "don't get bit" but thats basically impossible if you enjoy the outdoors, especially in more wooded areas like northern Ontario. You can't just wear a full body bug net the whole time. I mean I guess you could but it'd be miserable.
