Did you know dry ice can be used to eliminate unsightly mole or gopher tunnels from your lawn? Dry ice pellets can be used to eliminate these lawn pests without endangering children or family pets. Just put a handful of dry ice pellets down each hole you find, and cover the hole with soil to seal the opening.
As the dry ice sublimates into carbon dioxide gas, which is heavier than air, the gas will settle into the underground nest, suffocating the moles and gophers by displacing their oxygen where they feed and live. Using dry ice is safe and non-toxic and leaves no mess. Make sure to follow all dry ice safe handling precautions.
