So I finally have my deck up and running (nothing like vero95's!). Unfortunately, from my experience last summer, there can be a fair number of mosquitoes in my backyard. Short of getting my deck completely screened in, what are the options for mosquito control? Does anyone have first hand experience with the various types of flying insect control? I see electronic bug zappers, and various restaurants have those zappers with blue lights. What about the propane powered ones? Do they work?
