In the urban landscape a curious detail attracts attention: balconies and windows decorated with old CDs that rotate according to the wind. What seems like just an improvised decoration or an attempt to reuse old supports to add charm to the environment is, in reality, an ingenious and economical strategy to keep away pigeons and some insects, such as flies.
The secret is in the light. The mirrored surfaces of the discs reflect the sun’s rays, producing sparkles and flashes that change direction as the wind blows. This reflection creates a visually unstable environment, which confuses and annoys birds and insects. The result is that many pigeons prefer to take refuge elsewhere, leaving balconies and windows free.
In addition to preserving the cleanliness and aesthetics of the facades, the measure helps prevent diseases. Pigeons, although they appear harmless, are vectors of fungi and bacteria that can cause respiratory problems and infections.
Do it yourself at home
More than a visual trick, the method has gained popularity because it combines practicality, economy and sustainability. Anyone can make a “CD clothesline” in just a few minutes by hanging records with nylon thread or fishing line. The more CDs and different angles, the more effective the result will be,
The technique, however, is not a permanent solution. In places with a large concentration of birds, experts recommend combining CDs with other physical barriers, such as nets, sticks or specific repellents.
