Keeping outdoor trash cans free from rodents requires a combination of proper maintenance and smart practices. First, always use trash cans with tight-fitting lids to block access to food scraps. Regularly clean the bins with a disinfectant to remove odors that attract pests. Avoid overfilling the cans, as spilled trash can lure rodents. Place trash cans on a raised platform or hard surface to make it harder for rodents to climb. Additionally, consider using rodent repellents like peppermint oil or commercial deterrents around the bins. By following these steps, you can significantly reduce the risk of rodent infestations near your outdoor trash areas.
