Almost everyone that grows anything has experienced deer and/or bird damage to plants, whether they are growing food or ornamental plants, on a commercial scale or just for yourself. Now there is an easier way to deter deer and birds by using the Deer Shield and Bird Gard products. The Deer Shield Pro and Deer Shield Super Pro use digital recordings of aggressive, hostile and territorial deer to trigger a primal fear and flee response, effectively and humanely controlling deer. The Bird Gard works in a similar way by broadcasting digital recordings of distressed and alarmed birds, along with the sounds made by their natural predators. This triggers a primal fear and flee response. Pest birds soon relocate to where they can feed without feeling threatened.
