Scuttle flies, also known as phorid flies, are a common nuisance around outdoor trash cans, attracted by decaying organic matter. To prevent these pests, follow these effective strategies:

1. Regular Cleaning: Wash trash cans weekly with soap and water to remove residues that attract flies. A mixture of vinegar and baking soda can help eliminate odors.

2. Secure Lids: Use trash cans with tight-fitting lids to block fly access. Ensure lids are always closed, especially in warm weather when flies are most active.

3. Proper Waste Disposal: Wrap food scraps and organic waste in sealed bags before tossing them into the bin. This reduces odors and limits fly attraction.

4. Natural Repellents: Sprinkle diatomaceous earth or essential oils like eucalyptus or peppermint around the trash can to deter flies naturally.

5. Regular Trash Removal: Avoid letting garbage sit for too long. Schedule frequent pickups or take out the trash before it overflows.

By implementing these methods, you can significantly reduce scuttle fly infestations and maintain a cleaner outdoor space.
