insect foggers

[greenstreak]

I travel a lot up the st John's river and stay around a lot of wooded areas. I am wondering how effective it would be to use an electric fogger on insects. Does the fogger leave a residue when used? I wanted to spray around my boat. I am wondering if it will harm the finish on fiberglass? Would it work on blind mosiqutos? I just cam back from Hontoon state park over the weekend. My boat was completely covered with thousands of blind mosquitos. Most dead all over it.

thanks
