New data indicates that Bird Free is 100% effective in dissuading feral pigeons from roosting at night for at least four years after installation.
Up until now, Bird Free has stated, via HSE that the efficacy of the product lasts for 3 months, however we now have new data to prove otherwise.
This data derives from a test that was done on a night roost sit at the Veterinary Clinic of the University of Pisa in San Piero a Grado. From day 0 (the day of installation) the number of pigeons were counted every day, up to 4 years. The figures from this shows that, after installation of Bird Free, not one single bird was observed roosting at night.
Based on the reported results, HSE has now granted the efficacy of the product a minimum of 4 years.
