In the heart of Sweetwater, Texas, the central courtyard of Rolling Plains Memorial Hospital had a real bird problem--grackles. The beautiful 70’ X 70’ open courtyard is adorned with a green lawn, flowers, trees and a picturesque winding sidewalk. Patients enjoyed strolling through the courtyard, and hospital staff often gathered outside to take a break from their busy schedules. While hospital administrators hoped the courtyard would attract pretty songbirds, grackles invaded the area by the hundreds from the surrounding farmland. The noisy birds created quite a mess. The need for bird repellents was becoming obvious.
The hospital’s Plant Operations Manager was surprised at the number or birds and the awful smell of droppings, which the groundskeeper had to clean up every morning. The bird droppings also became a health hazard, since patients often came out in slippers and tracked in the disease-ridden bird waste back into their rooms. To make matters worse, the mounds of grackle feathers were beginning to interfere with the hospital’s air conditioning system. Something had to be done to get rid of birds.
First was to remove the bird feeders in the courtyard, but the grackles just kept coming. They tried balloons, rubber snakes, and plastic owls, but those bird deterrents didn’t work. So they finally called in a professional bird control company who recommended a Sonic Bird Repeller. They mounted two speakers on the roof, about 15 feet up, and 40 feet apart. They pointed the speakers toward the courtyard and “turned on the music.” With the windows closed, it sounded like a crow outside. To the grackles, it sounded like imminent danger--distress and predator calls that convinced the annoying grackles that they would be hunted and attacked unless they fled. And flee they did, never to return. In no time at all, the beautiful courtyard was clean and tidy, restored to its natural outdoor fragrance.
Many hospitals and medical centers like the one in Rolling Plains have had to deal with pest bird infestations. Hospital administrators have learned that effective bird control is a necessary part of hospital operations. With today’s tight operating budgets, administrators don’t want to face high maintenance and cleanup costs precipitated by pest bird infestations.
Grackles, pigeons, starlings and sparrows will be drawn to the many nooks and crannies of a hospital's courtyards, break areas, lunch and snack areas and of course, its signs, rooftops and even windowsills. When these areas are covered with droppings, they pose a health hazard, since the bacteria, fungal agents and ectoparasites in droppings and nesting materials have been known to carry any of 60 diseases--including histoplasmosis, encephalitis, salmonella, meningitis, and toxoplasmosis, even the West Nile virus. The resulting clean-up and maintenance costs in dealing with these droppings can be prohibitive. Excessive bird droppings on walkways and entry points can also cause dangerous slip-and-fall hazards--a huge legal liability for any institution.
Today, bird control measures run the gamut and are surprisingly effective. These include various bird deterrents, bird repellents, and bird barriers used by institutions across the country. In addition to Sonic Bird Repellents mentioned above, you might consider using the following to get rid of birds:
Bird Spikes. Ideal for preventing larger birds from landing on rooftops, ledges and other areas, bird spikes come in 3-, 5- and 8-inch widths and two-foot sections. The blunted spikes won't harm birds or maintenance crews, and you can get either stainless steel or rigid U.V.-resistant unbreakable polycarbonate. The poly spikes can be used around cell phone antennas and other RF antenna systems. If you have problems with birds clogging your rain gutters, look into the Gutter Spike, which comes in two-foot long strips. They present an effective bird barrier.
Bird Netting. Hospitals and health care centers have long used bird netting to physically exclude pest birds out of specific areas. Bird netting comes in various types and mesh sizes. For large birds like pigeons or seagulls, use a 1-1/8” to 2” mesh size. For sparrows or starlings, opt for a 3/4" mesh net. Better bird netting usually meets ISO 1806 protocols, is U.V. stabilized, flame resistant and rot- and water-proof. Also note that netting now comes in various colors to blend in better with its surroundings.
