Some natural deterrents that keep frogs away include saltwater, citric acid and caffeine. Demolishing structures where frogs hide, such as piles of leaves and wood, also keeps frogs away.
Repel frogs by mixing a solution of saltwater and spraying it around the areas that frogs frequent. The solution deters frogs by burning their skin when they hop over the sprayed area. Frogs that get in direct contact with a 16 percent solution of citric acid or a 2 percent solution of caffeine usually die. Finding breeding locations of frogs and scooping their eggs regularly also deters them from inhabiting and breeding in the compound.
