Millipedes are common pests that can invade outdoor trash cans, attracted by moisture and organic waste. To keep them away, follow these effective strategies:

1. Keep Trash Cans Dry: Millipedes thrive in damp environments. Ensure your trash cans have tight-fitting lids and place them in a dry, shaded area to reduce moisture buildup.

2. Regular Cleaning: Clean your trash cans weekly with a mixture of water and vinegar or mild detergent to eliminate food residues and odors that attract millipedes.

3. Use Natural Repellents: Sprinkle diatomaceous earth or cedar chips around the trash can. These natural substances deter millipedes without harming the environment.

4. Elevate the Trash Can: Place the bin on a raised platform or stand to prevent millipedes from crawling inside. This also improves airflow and reduces moisture.

5. Seal Garbage Bags: Always tie garbage bags securely to minimize odors and prevent millipedes from accessing food scraps.

By implementing these simple yet effective measures, you can significantly reduce the likelihood of millipedes infesting your outdoor trash cans. Regular maintenance and proactive pest control are key to keeping your outdoor spaces clean and pest-free.
