Dealing with wasps around your outdoor trash bin is frustrating and potentially dangerous. The good news is that you can effectively discourage them from setting up shop with a few consistent habits. The most crucial step is to eliminate their primary attractants: food and shelter.
Start with rigorous cleanliness. Rinse out your trash bin regularly with a mixture of water and vinegar or a mild bleach solution. This removes the sugary residues and food smells that draw wasps in. Always ensure your trash bags are securely tied and that the bin's lid closes tightly without gaps. For extra protection, sprinkle a few tablespoons of peppermint oil or dish soap around the rim and base of the bin; wasps strongly dislike these scents.
Consider the bin's placement and environment. If possible, keep your trash bin in a shaded, cool area, as wasps prefer warm, sunny spots to build their nests. You can also hang a fake wasp nest nearby; wasps are territorial and will typically avoid building a nest close to another colony. For a long-term solution, inspect your bin weekly, especially in the spring and early summer, and immediately remove any small, starter nests you find with a long-handled tool. By maintaining a clean, uninviting environment, you can enjoy your outdoor space without uninvited stinging guests.
