Water Bottles on Walls: Myth or Solution for Urban Cleanliness?

Skepticism and Lack of Scientific Evidence
Despite the popularity of these explanations, the scientific community remains skeptical about the actual effectiveness of water bottles as a deterrent for animals. There is a lack of concrete studies confirming these theories, and many consider the practice more of a social placebo than a truly effective solution.

A Symbol of Care for Shared Spaces
Regardless of its practical results, the presence of the bottles can be seen as a sign of citizens’ desire to take care of public spaces. Beyond the actual effect, they represent an invitation to reflection and collective responsibility, emphasizing the importance of keeping cities clean and welcoming for everyone.
