Keeping outdoor trash cans free from flies is essential for maintaining hygiene and preventing pest infestations. Here are the most effective methods to achieve this:

1. Use Tight-Fitting Lids: Ensure your trash cans have secure, airtight lids to block flies from accessing waste.

2. Regular Cleaning: Rinse bins weekly with soapy water or a vinegar solution to eliminate residues that attract flies.

3. Bag Trash Properly: Double-bagging food scraps and sealing waste tightly reduces odors that lure flies.

4. Natural Repellents: Sprinkle baking soda or place citrus peels at the bottom of the bin to neutralize smells.

5. Dispose of Waste Frequently: Avoid letting trash sit for too long, especially in hot weather, to minimize fly attraction.

6. Use Fly Traps or Zappers: Install traps nearby to catch flies before they reach the trash can.

By following these steps, you can significantly reduce fly problems and maintain a cleaner outdoor environment.
