Considering frogs and toads very much like mosquitos and mosquito larvae as a food source, what most likely happened in Kathy Durrum's situtaion is that by introducing mosquito dunks and killing the larvae they removed the food source for the frogs which caused a large number of them to starve to death. Removing the dunks allowed the mosquito population to proliferate which then also allowed the predators of mosquitos, frogs and toads, to also proliferate. Any time you remove or reduce the amount of an animal from an environment that is a small ecosystem you're doing damage to that entire system, not just the one specific animal in it.

They've been croaking here more this week, but I was hearing a few in Feb. and I saw the first eggs a few weeks ago. They went through a freeze, so I don't know if that affected them or not...time will tell. I don't think there will be as many as the last couple of years since we kept the water from collecting on top of the pool this winter. We heard some on and off throughout the winter. I noticed the Indian Plums were starting to bloom in the woods.

They are just there to have their meals. It will be irritating but they don't do any harm to you. I used to do the same, spray chemicals or bug sprays, but one day my daughter thought me something which I forgotten long back. She is studying in Sunnybrook School in Ontario, and they had a class one day about the frogs, tree frogs etc. That day she made me realize that these frogs and toads are important for proper bio balance. Stop hurting them and try simple steps like those mentioned by Walker.

Hoping someone can point me in the right direction to get an id on this stuff in my pool I’ve gotten everything from frog eggs to algae to caterpillar frass from a nearby tree. It vacuums up easily and is not attached to the liner
