I, unwittingly, purchased water plants from a source that I think had tadpoles. Soon after I noticed multiple very small swimmers. After spraying my acquatic plants with liquid Seven, the population diminished a bit--I think. I now notice a more mature group of tadpoles. Knowing they will turn into frogs, I must discard of them as this is a contained area in the middle of my house. There is no escape for them as all four sides of the atrium are enclosed--it is only open to the sky. I would appreciate any advice on this matter. Already, the sounds of night critters from inside and outside of the atrium are equivalent to a symphony orchestra. I actually enjoy the sound but I don't think I could handle hopping frogs all over the place. Thanks for your support. CAT
