Keratin is the protein extracted from skin modification such as horn, nail, wool, hair, claws. This protein is not easily digestible. Mainly hairs of human and cattle pollute the environment and also collapse our drainage system. For this type of waste management Tineola bisselliella shows the best result. We study their feeding behaviour in different parameter like pure hair; hair and salt water; hair and blood water; hair, dust and blood; hair and shampoo and hair and coconut oil. Among them hair with dust and blood is most preferable and clean hair means hair and shampoo is less preferable. We also study the impact of temperature, humidity and light intensity on different life cycle stages and how that parameters related to hair consumption that is also established.
