Living in Arizona and the mosquitoes are finally a big nuisance here. Recently they have started to infest my small duck pond which is an issue because my son loves to feed and pet the duck on a daily basis. I have tried small fish, but my duck just likes to eat all of the fish within a day or so. Does anyone have a solution to this? My duck has a 10x10 foot run with an above ground pool that I built. I typically drain it once a week. My 6 month old duck doesn't seem to be eating them and once the mosquitoes have moved in the duck doesn't even go in the water.
