Do you want mosquitos? Or are you trying to get rid of them? Mosquitos are attracked to standing water. If you have any containers that have water in them dump them. Old tires fill with water too. Remove them. Even a pets water bowl should be dumped everyday. Standing water in swimming pools that are not filtering are also a breeding ground. Stagnet ponds too. By removing the places for them to breed you will get rid of the problem. Note also down South they will be especially bad this year because of the mild summer.
