Mushrooms and Dish Soap

I had a bunch of mushrooms in my lawn. I knew if I just pulled them out or raked they out they would be back the next day. I checked the internet to find out what to do. SOO SIMPLE! Mix 3 tablespoons of Dish Soap in one gallon of water. With a large screw driver, poke holes all around and in the mushrooms. Just pour the mix over the holes and around the little bas%*?3. The next morning over half were gone. We had a couple of days of rain. This morning you can't see any trace of them. Cheap, safe, and it really works.
This should also keep them from coming back for a good spell.
