Flesh flies are a common nuisance around outdoor trash cans, drawn by decaying organic matter. To keep them away, follow these proven methods:

1. Regular Cleaning: Empty and scrub trash cans weekly with a mixture of water and vinegar or bleach to eliminate odors and residues that attract flies.

2. Secure Lids: Use tightly sealed lids to block access. Opt for bins with locking mechanisms or weighted tops to prevent flies from entering.

3. Natural Repellents: Place bay leaves, mint, or citrus peels inside the bin—their strong scents deter flies. Alternatively, spray a solution of essential oils (e.g., eucalyptus or lavender) around the bin.

4. Bags and Liners: Double-bag waste, especially food scraps, to contain smells. Tie bags securely before disposal.

5. Pest Traps: Hang sticky fly traps or DIY traps (like apple cider vinegar with dish soap) near bins to catch adult flies.

6. Sunlight and Placement: Position bins in sunny areas, as flies prefer shade. Keep them away from doors or seating areas to minimize human contact.

By combining these strategies, you can significantly reduce flesh fly infestations and maintain a cleaner outdoor space.
