x2 on this method. It has worked well for us. Place bags on tree limbs if possible which will be in the sun. The water bag greatly depends on using the method along with the suns rays. You will want to keep the water filled bags in the sun as much as possible.Has anyone tried a gallon ziplock filled with water and a penny? I use one by my front door (where the girls like to hang out and poop) and my flies have cut back 90% percent, seriously-crazy right? I haven't used one in my coop yet (no need). It worked wonders for that one spot! I wonder if it'll work in the coop as well?
