Horse flies are a common nuisance around outdoor trash cans, drawn by the smell of decaying waste. To keep them away, follow these proven methods:

1. Use Tight-Sealing Lids: Ensure your trash cans have secure, airtight lids to block odors that attract horse flies.

2. Clean Bins Regularly: Rinse and disinfect trash cans weekly to eliminate food residue and bacteria that lure pests.

3. Apply Fly Repellents: Spray natural repellents like vinegar, essential oils (e.g., eucalyptus or citronella), or commercial insecticides around the bin.

4. Keep Trash Bags Sealed: Double-bag waste, especially food scraps, and tie bags tightly to minimize odors.

5. Place Bins Strategically: Position trash cans away from high-traffic areas and in shaded spots, as horse flies prefer warm, sunny locations.

6. Use Traps or Bait: Hang sticky traps or bait stations near trash cans to capture horse flies before they become a problem.

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