I didn't know that you lived in CB. When did you leave here?
We live out in the country, up on a hill, where there is no standing water, and always a breeze, which is probably why we are not bothered by mosquitoes.
I have weiner roasts and we sit out and visit way past dark and no one is bothered by mosqitoes.
However I am going to do more research on which is the best way to go. I know there is a risk, as there is a risk with anything, coyotes, halks, owls etc. But there are also the dangers of cancer from repeated exposer to pesticides.
I don't use flea preventers unless I see a flea, and most years I never see one, if I do, I treat one time, unless a second dose is warranted.
