Black scavenger flies can quickly become a nuisance around outdoor trash cans, spreading bacteria and creating an unsanitary environment. To prevent these pests, follow these effective strategies:

1. Regular Cleaning: Wash trash cans weekly with soapy water or a bleach solution to eliminate food residues and odors that attract flies.

2. Secure Lids: Use tightly sealed lids to block flies from accessing waste. Consider bins with locking mechanisms for extra protection.

3. Natural Repellents: Sprinkle baking soda or place citrus peels inside the bin to deter flies naturally. Essential oils like eucalyptus or peppermint can also repel them.

4. Proper Waste Disposal: Avoid throwing raw meat or overly moist food scraps directly into outdoor bins. Double-bagging such waste reduces odors.

5. Trash Placement: Keep bins in shaded, well-ventilated areas away from direct sunlight, which accelerates decomposition and attracts flies.

By maintaining cleanliness and using preventive measures, you can significantly reduce fly infestations around your outdoor trash cans.
