That is what was said. It is my experience that any standing water in the
garden attracts mosquitos and there are the tiniest tadpoles (with heads
less than a millimeter across) before the strange looking larvae appear. By
that I mean at less than a tenth of the size that I would consider a
frog/toad tadpole, and there are gazillions of them.
