For the flying yard insects-you should consider the Flowtron Electronic Insect Killer. I have had this type of thing before and they barely made a dent in the bugs but this one is amazing! I did my research and read reviews before ordering one and am not disappointed. I live in NW Georgia and with all the recent rains, the mosquitos are already out in full force. I have only had it up about 5 days but we have yet to even see a mosquito near any of us and we stay outside a LOT! There are 3 sizes-I got the big 1 1/2 acre one (we have 10 acres).  It has "attractant cartridges" and every morning there is a huge pile of bugs under it. Only drawback is it sounds like a mini machine gun so hang it at a bit of a distance from your outdoor sitting area! lol
