What is the purpose of a porcupine wire?

The purpose of a porcupine wire is to repel birds from landing on surfaces. This type of wire is designed with sharp spikes or points that create an uncomfortable surface for birds, discouraging them from perching or nesting in unwanted areas. By implementing porcupine wire, property owners can effectively manage pest birds that may cause damage or create sanitation issues. The design is specifically tailored to deter larger birds without harming them, offering a humane solution for keeping these animals away from particular locations.

The options related to trapping animals or attracting wildlife do not align with the specific function of porcupine wire, which focuses on repelling rather than capturing or enticing animals. Additionally, signaling danger to other animals is not associated with this wire's role, as its primary application is about preventing landing rather than communicating threats.
