Bee flies can be a nuisance around outdoor trash cans, but there are several effective methods to keep them away. First, ensure your trash cans have tight-fitting lids to prevent odors from escaping and attracting insects. Regularly clean the bins with a mixture of water and vinegar or mild detergent to eliminate food residues and sticky substances. Additionally, consider placing trash cans in shaded areas, as bee flies are more active in direct sunlight. Using natural repellents like peppermint oil or citrus peels near the bins can also deter these pests. Finally, schedule frequent garbage pickups to reduce the buildup of waste that attracts bee flies. By following these steps, you can maintain a cleaner and pest-free outdoor space.
