Frogs and toads are tremendously beneficial to gardeners and anyone who loves to spend any time outside. They eat thousands of insect pests, including pesky mosquitoes and flies. (A single adult toad can eat as many as 10,000 insects every summer.) They will also fill the air with their (generally) relaxing songs, and be interesting and well-behaved neighbors to have around, especially if any of your children are budding naturalists.
