Introduce fish that eat tadpoles. Koi
, Goldish or a whole lot of betta fish. Bettas are hardy and can survive almost anywhere. I guess you should get about 10 males and 20 females. It's going to cost a whole lot. There are a lot of snakes that eat frogs. The best option is to introduce predatory fish. Maybe Oscars? Arowanas? What fish are in the pond at the moment?
the original poster wished for something natural, and this would be exactly opposite.
personally i feel strongly against this topic. "Introducing" things to non-native areas is why we have the restrictions on the fish and aquarium plants we have today. this same concept occurs on the saltwater side too ( like lionfish being found in florida and algaes taking over the west coast )
adding something random throws off the cycle of things. you may not even realize it but these frogs are reproducing in large numbers prob. because food sources are abundant. take away the frogs and the more bugs you'll see. now add Koi
and a year from now what eats them? you cant have too much cheese, fix the problem by buying mice, then expect to fix that problem with cats.
not only whatever is added to "fix" the problem will be eating tadpoles and/or frogs but they could also eat the other wildlife and/or provide an abundant source of food for some other type of predator to reproduce like jack rabbits. think about it. if you added a few snakes for the situation and they have all these frogs to feed on, they to will be reproducing all over. they wont make noise like a frog but they could cause a nasty bite when attempting to enjoy this lake. i know i wouldnt want to meet a family of water mocs or copperheads
to sum it up, im not looking for an arguement rather hopefully a mature debate. incase your wondering who's this tree hugging hippie, thats not even my motivation for this education. yes, i could claim we are visitors to this earth and many were here before us and will be after us blah blah blah but really it comes down to the simple fact that this is my hobby which i enjoy ( as im sure many others ) and i would like to continue to enjoy and share it with others.
so as for my natural way of getting rid of them, keep them there or put ear plugs in
