Hi all, for the last few months, we have Ducks swimming in our pool, sitting on the pool fence and making a hell of a mess. I have tried capguns, throwing tennis balls which haven't worked.
I've thrown brooms at them etc.
We have a shark kite floating above the pool with Silver streamers for the last few days, but they still sit on the fence. Next step is to talk the boss into putting spikes on the fence, but they're not cheap.
Also might be an excuse to buy a M4A1 Gel Blaster. ;-)
From my past experience, ducks will only stay for a couple of weeks, have ducklings and then move on.
Then you can use a high-pressure cleaner to clean up around the pool. The pool water will clean with the usual pump / filter.
