Chlorhexidine, also known as Nolvasan, is a powerful disinfectant that effectively kills bacteria, viruses, and fungi in reptile enclosures. It is commonly recommended due to its safety for reptile cages, as it leaves no toxic residue or fumes when diluted according to the product instructions. In addition, veterinarians utilize it for wound irrigation as it is both safe and effective. Unlike other disinfectants, chlorhexidine does not produce any toxic fumes, making it a safer option for both reptiles and their keepers.
