Mosquito larvae

[Chickenmarsala]

Hi everyone!
I was out with my duck today and noticed that in his swimming pool there were little mosquitoe larvae swimming around in there. Is that dangerous for him to drink? And is there anything I can put in the water to get rid of them? I change his water every week and it's usually still pretty clear by the time I change it. Thanks everyone!

Mosquito are a fav of ducks so I would think the larvae would be too. Great for keeping the population a bit more under control.
