People often sanitize their trash bins to eliminate unpleasant odors, reduce the risk of attracting unwanted pests like insects or rodents, and maintain cleanliness in their living environment. Over time, organic waste and other materials deposited in the bin can decompose and produce foul smells, as well as become a breeding ground for bacteria and other pathogens. Sanitizing the trash bin helps to kill germs, remove lingering odors, and generally make the area more hygienic. Additionally, it can prevent the spread of illness-causing bacteria and maintain a healthier living space for occupants.
