Some restaurants (with outdoor seating) have hundreds of pigeons, crows, blackbirds, starlings, which are infesting the roof tops, grounds, and railings where food is being prepared or served. Because of the sheer size of each of these areas, this is a major challenge, especially outdoors.   

Placement of Birdbuffers at upwind side of the roof top (or under eves) repels birds with a grape vapor over the top of the area where birds fly, causing them to leave the area.

 

When birds see food and/or "droppings" on the ground, these act as attractions. Repel birds with this automated vaporization process, which uses the fluid Rejex-It Fog Force.  The Birdbuffer Q2 and the Birdbuffer TD, produce a constant, virtually invisible, dry-vapor, (then clean up the mess once and for all).  After 1-3 months into the program, the active birds have left the area (and take their mess with them).  Some birds can withstand discomfort on a temporary basis.  But as vapor-time goes on, they start leaving the area. Effective with pigeons, crows, blackbirds, starlings, it does not harm them, just keeps them away.

After 10 years and a patent, Birdbufer LLC now offers several units as the  Birdbuffer Q2, a self-contained, vapor machine (with digital timer), the Birdbuffer TF, a handheld thermal fogger to get rid of stubborn birds, and the newest Birdbuffer TD, a smaller indoor version of the Q2 system for use in covered areas, patios, or under eves.  You can see these products at birdbuffer.com, then click birdbuffer products for a list.
