For my Whites Tree frog's terreium, daily cleaning includes removing any visible feces or other waste, i.e. dead crickets, and cleaning and refilling his water bowl. I then clean his terrarium throughly every 2 to 3 weeks. I am a clean freak when it comes to my frog’s housing area and make sure everything—the tank, furnishings, soil, moss, etc..—is either thoroughly cleaned or replaced.
