Bug zappers WORK!
I used to work at a Sewage Plant...Lots of standing water... Lots of mosquitoes!
I had them install a one half acre bug zappers, because the mosquitoes were feeding the spiders, (I kept getting bit by those rascals - the spiders)
I would leave the bug zapper on, and by the next day, I would think some one unplugged it! Found out that the mosquitoes covered the entire thing!!
Finally ended up burning the bug zapper out! (Must of used it too much when it was new??? After only two seasons...sheesh).
Got an acre and a half for my house...When the neighbor cut the tall weeds down in the field next to my house, I didnt have a single bug, after that! (Before that, there were many!)...
Ok, my two cents for what its worth, and a wee bit extra for the collection plate...
