Does anyone have any idea how I can remove/drastically reduce (to the point of elimination) the water snails in my wildlife pond. There are too many to pick out by hand and there are so many small ones that are easily missed.
Currently other occupants include frog tadpoles (until they are eaten) newts, dragon fly larvae, large diving beetle, other water beetles, water boatmen, leeches and presumably a lot of other things. I do not want to damage them. However, it would be nice if this year a few of the tadpoles managed to make it to the frog stage. I hope to acquire some toadspawn and/or toad tadpoles and/or mating toads.
