Just like my mother-in-law, its mere presence may be enough to drive living creatures away.
Garden Guard Scare Owl
The Garden Guard Owl is more than an attractive decoration! Hung at your window he'll keep birds from flying into the glass. Nailed to a tree or building, or hung from a fence, he'll deter pigeons, squirrels, crows and seagulls. Add a touch of whimsy to your home or garden with these silent guardians. No matter how they are displayed, they will stand as deterrents to many of the pests who share a keen interest in your garden. Made of black powder coated quality steel, these handsome creatures are weather resistant. Move frequently so pests don't get used to its silhouette.
HOW does it work? I doubt that pesty garden squirrels would forego my vegetables just because of this unless it makes a sound or hits them with a lazer- I have tried the sonic thing, animals be gone, Chili powder. And NOTHING works!
