The program of flock dispersal consists of the following procedure: Installation of bait stations at specific target areas where the pest birds normally roost and perch. Initially, a pre-bait feed is used to attract the birds and become accustomed to the feeding stations. After the birds begin to regularly feed from the bait stations, we substitute a material called “Avitrol” that contains flock-alarming properties, Once ingested it will cause the bird to react in a way that will frighten the remaining flock away from the site.
