Drive pest birds away with BirdXPeller PRO Programmable species-specific repeller The new sonic repeller from BIRD-X uses birds own distress calls to create a "danger zone" - it frightens infesting birds away for good. Proven and Guaranteed. In extensive field tests, BirdXPeller PRO has significantly reduced or completely eliminated bird infestations. If youre not happy with the unit, you can send it back - call us for details please. How it Works:BirdXPeller PRO features birds distress cries on a microchip (supplied by a major American university). The birds perceive danger when they hear these sounds. They become agitated and disoriented: they think their flockmates are in trouble so they flee the area... never to return. Species-Specific and Programmable:Target your birds with a species-specific approach - not scattershot. There are eight bird sounds on the unit, so choose the ones that are invading your space! In fact, some of the eight are predator calls - if you add these to your program, youll give the birds even more of a sense of danger. Then, if you need to repel different birds in the future, simply re-program your BirdXPeller PRO.) In addition to programming the selected birds, you can also program volume, time off periods (between sound blasts), and whether the bird sounds play in random or sequential order. These programming options make it virtually impossible for birds to get used to any one pattern. Harmless:BirdXPeller PRO attacks the birds with loud, terrorizing sounds, but it doesnt harm them.
