i let a little puddle sized pond i dug stay wet and got a ton of frogs out of it. i noticed tadpoles in there one day so i made sure the water didn't run out and i fed them table scraps of lettuce, watermelon, tomatoes, banana peels, etc. i fed and watered them for a few weeks and now i have tiny frogs all over the place. they are in every corner of the garden, i have to look down everywhere i walk to make sure i'm not stepping on any. sorry for the tangent, but the talk of beneficials gave me an in to share my surprise frog pond story
the spray i use is: BT, molasses, dish soap, garlic and pepper juice, and sometimes neem.
