Introducing the world's first-ever indoor laser bird repeller! Bird BLazer utilizes proven, state-of-the-art, "fat beam' laser technology to remove birds without harming them. Laser beams are well-documented to chase away pest birds. Constantly changing laser beam patterns disrupt some of the most notoriously pesty birds like pigeons, sparrows, starlings, swallows and other birds. The beam seeks out their roosting-spots, alarming and confusing them, and they flee. This technological breakthrough makes current hand-held, labor-intensive lasers obsolete.
