Lacewings, while beneficial for gardens, can become a nuisance when they swarm around outdoor tables. To prevent them from being attracted to your table, start by eliminating light sources at night, as lacewings are drawn to bright lights. Use yellow or LED lights instead of white bulbs, which are less appealing to insects.

Keep your table clean and free of food residues, especially sugary spills, which can attract lacewings. Regularly wipe down surfaces with a vinegar-water solution, as the scent repels many insects.

Planting natural repellents like lavender, mint, or citronella around your outdoor dining area can also deter lacewings. These plants emit fragrances that lacewings dislike.

For immediate results, consider using a fan near your table. Lacewings are weak fliers and avoid windy areas. Alternatively, place a bowl of soapy water nearby to trap them.

By combining these methods, you can enjoy your outdoor space without unwanted lacewing visitors.
