invest in a "guard coyote?" lol, maybe put a couple of floats in your pool to scare them off, like an alligator one or something
Anyone have any good ideas on how to keep ducks out of my pool? They're nice and all but I have to clean out the crap afterwards all the time!
You could do like the oil sands plants do. Around their tailing ponds they set off explosions at intervals to scare the birds away. LOL
Seriously, record a shotgun being fired, and set up a motion sensor aimed at your pool, which would play the shotgun on a large speaker. That will scare them away. True there is very little open water in California, so that would be cruel to the poor ducks. A robot pool cleaner that runs across the bottom all the time?
I used to have the same problem in Pennsylvania. Don't they make pool alarms? They are supposed to alert parents that a child has fallen in. I'm sure ducks have parents too, so it should work.
