Foothill-Sierra Pest Control was faced with excluding a large population of pigeons roosting between two historic buildings in downtown Sonora. We did not want to risk piercing the walls or roofs of these buildings. The first prototype, created and built by Jim Tassano, with Kraig Stewart’s help, worked well. The job was then taken up by our vertebrate specialist, David Adragna, who designed and built, with Bill Breidenstein, a strong, long-lasting, modular version of the prototype.
No hardware penetrated the roof or walls of either building.
The pigeons have moved on, and the flies are gone.
