Bird behaviour is instinctive. It is conditioned by basic needs: food and water, shelter, warmth, security (from predators). By means of sensory stimuli that alter birds’ instinctive responses, Bird Free:
To eliminate long-standing infestations, pigeons must first be deterred from returning to their nests/night roosts. Pigeons instinctively return to their nests/night roosts every evening, and will make all possible efforts to overcome physical barriers to them doing so. Consequently, traditional methods will often fail to exclude resident pigeons from such sites.
Many facilities managers have finally been able to solve persistent pigeon problems with Bird Free where other methods have failed. After installing Bird Free, one client who had, for several years, tried unsuccessfully to get rid of pigeons from a public building by using spikes and nets, commented: “It ought to be called Ronseal, it does exactly what it says on the box.”
