What can I do to get rid of the frogs?
Every summer for the past three years frogs have invaded my yard and every morning I find bounds of mushrooms in yard what can I do to get rid of the frogs?
Frogs are protected in many States. It would be a good idea to contact your agricultural department on this specific situation. Their people would be the most helpful.
Round-up by Monsanto has been reported as an incidental destroyer of frogs and toads when applied for its intended purpose which is weed control.
Frogs do so much good in nighttime insect control. Like bats, they are worth their weight in gold.
I don't know how you are tying in mushrooms with frogs. It is reported that certain fungi have a deleterious effect upon frogs.
Heavy rains or overwatered lawns can bring about both frogs and mushrooms; the mushroom fungi attracted to such a lawn, and the toad/frogs attracted to the insect life that is fostered in such a condition.
By watering in the early morning and not at night, you might have a progressively improved exclusion of the specie that you question. It is important to aerate your lawn, and if you use a roller that has multiple prongs over its surface designed for the purpose of punching holes in the lawn, you might accelerate water absorption.
I've run out of ideas. If anyone has additional suggestions after reading this posted answer, I'd appreciate a communication.
Gheri, thanks for the opportunity to help you. I hope I've been a help.
