The average toad will eat 50-100 insects every night - that's 10,000 to 20,000 insects throughout a gardening season. They will help eliminate garden pests such as flies, grubs, slugs, cutworms, grasshoppers, and anything else they are fast enough to catch. You can encourage toads to take up residence in your garden by providing shelter and water, and by using gentle pesticides that won't hurt your warty allies.
Toads prefer homes that are humid and out of the wind. You can build a toad residence by digging a shallow depression in the soil and covering it with a board. Don't forget to leave a door! A birdbath at ground level would provide just the right amount of water for your toads' daily needs, but if you would like to see them raise a family in your garden, consider adding a water garden or small pond. Once they move in, they will stay for years, so the small effort required to attract them will pay off many times over.
