Where I live, we used to have tons of frogs. The city actually built a freeway bypass to prevent too many flat frogs. Didn't work. Anyway, the frogs quickly vanished around the same time we started spraying to reduce the spread of West Nile. Don't know if it was the food source or if the spray killed the tadpoles, but unintended consequences are a thing. A knock-on to that is we now have a growing roach problem.
