just wondering if its safe to leave the beetles in, i know my leo can eat them, she chooses not to, but would they be able to harm her, or spread bacteria etc, if i leave them in, they help keep the tank clean inbetween cleans such as eating mealworm sheds or eating a few cricket leg scraps or eating the traces of poo left on the reptile carpet, are they safe to keep them in between cleans and treat them as a mini hoover and clean them out when i clean my gecko out or move them straight away?
