Stable flies are a common nuisance around outdoor trash cans, but there are several effective strategies to keep them at bay. First, ensure your trash cans have tight-fitting lids to block access to food waste. Regularly clean the bins with a mixture of water and vinegar or bleach to eliminate odors and residues that attract flies. Using trash bags and sealing them properly can also reduce fly attraction. Additionally, consider placing trash cans in shaded areas, as stable flies prefer warm, sunny spots. For extra protection, use natural repellents like essential oils (e.g., eucalyptus or peppermint) around the bins. Implementing these measures will significantly reduce the likelihood of stable fly infestations.
