Alderflies can be a nuisance when they gather around your outdoor table, especially during warmer months. These insects are attracted to moisture, light, and organic debris, making your patio or garden a prime target. Here are some effective ways to prevent them from invading your space:

1. Remove Standing Water: Alderflies thrive near water sources. Regularly check for and eliminate stagnant water in pots, trays, or nearby containers.

2. Use Natural Repellents: Essential oils like citronella, eucalyptus, or peppermint can deter alderflies. Mix a few drops with water in a spray bottle and apply it around your table.

3. Install Yellow Bug Lights: Alderflies are drawn to bright white lights. Switching to yellow or LED bug lights can reduce their attraction.

4. Keep the Area Clean: Regularly clean your outdoor table and surrounding area to remove food crumbs, fallen leaves, or other organic matter that might attract pests.

5. Use Fine Mesh Screens: If alderflies are a persistent problem, consider using mesh screens or netting around your seating area to block them out.

By following these simple steps, you can enjoy your outdoor space without the annoyance of alderflies. Consistency is key—regular maintenance and preventive measures will keep these pests at bay.
