Millipedes can be a nuisance when they invade your outdoor table, but there are several effective ways to prevent them. First, keep the area around your table clean and free of decaying leaves or mulch, as these attract millipedes. Regularly sweep or hose down the surface to remove debris.

Next, create a barrier by sprinkling diatomaceous earth or crushed eggshells around the table legs—these sharp particles deter millipedes. You can also use natural repellents like citrus peels, cedar oil, or vinegar sprays, which millipedes dislike.

Ensure proper drainage near your table, as millipedes thrive in damp environments. Elevate the table slightly or place it on a dry surface to reduce moisture buildup. If the problem persists, consider using a mild insecticide labeled for millipedes, but opt for eco-friendly options first.

By maintaining cleanliness, using natural barriers, and controlling moisture, you can enjoy your outdoor table without unwanted millipede guests.
