We actually found a product that omitted a sound that the ducks did not like. We posted it on one of the polls by the pool, I was concerned that dogs around the pool or other animals would hear it. The reviews said they wouldn’t, it worked great! I’ll look it up shortly for ya!
Simple just get some of those blow-up floats I know some of the pool supplies have dolphins that stand in the pool they don't like they won't stay around long
We have a fake owl on our deck in the corner. We never had eucks or geese issues in the 8 years i have been on my property. We are located in the woods next to a lake so there are plenty of ducks and geese in the area
Really scary looking fake wolf's. With Fir and everything. Works for geese as well. 100% effective. I have also used cheap blow up beach balls and leave a bunch floating in the pool.
True story: We had Canadian Geese wreck havoc around our lake so we purchased real looking fake coyotes to scare them away which they did not do. During a property inspection a corporate inspector asked why we did not get real ones. Can't make this stuff up.
Floating alligator in the pool, if you have tall fencing you can affix the little iridescent windmills to it, along with the reflective ribbon. Also affix them to the railings at either end of the pool. There are noise devices that work and also automatic sprinklers.
