The novelty of seeing a pair of ducks descend on my swimming pool is wearing out. I'm not sure how they will leave the place, but after every two-hour visit, the surface of the water ceases to be pristine, and I know from past experience that hosting pigeons is a very bad recipe (worse, I fed them). They multiply and take over the place, make it filthy, and are very hard to shoo away once settled.
At this time the pool is still covered. The two ducks swim in the layer of water above the cover. Possibly once opened the problem will be solved on its own because, however minimal the chlorine I use, they may dislike it. So far I simply clap and that scares them to leave for a while.
What is an effective repellent for ducks? I thought about:
- A bucket of concentrated chlorine,
- Add some chlorine in the very shallow, still-closed, pool (with a risk of discoloring the cover),
- A motion sensor that triggers some crackling sound (rather tedious to put together for what I hope would be a temporary device + neighbors will not be amused if it's triggered in the middle of the night).
Can you share your experience about a (perfectly humane) way to nudge the ducks to move over to the plentiful ponds and creeks nearby?
