The Kroger supermarket on West 43rd Street in Houston has been invaded by thousands of noisy grackles. The big black birds have created a nuisance for the past couple of years, buzzing customers' heads, creating an ear-deafening din, and leaving unsightly droppings in their wake. The live oaks and sycamores surrounding the store’s parking lot provide an ideal perch for the birds. The store tried scaring away the annoying birds by setting off "bird cannon" on the roof, but the loud booms worked only temporarily, setting off car alarms, causing some people to call 911, and prompting police cars to roar in with sirens screaming and lights flashing.
Big birds like grackles can be a problem, especially if they’ve chosen your property to nest in. While you may be tempted to use lethal means like poisons or pellet guns, such methods are only marginally effective, as more birds will simply arrive to take their place. Here’s what today’s bird control experts recommend to solve a grackle problem:
Bird Chase Super Sonic
Ideal for discouraging all manner of birds from large open areas, the Bird Chase Super Sonic device broadcasts bird distress and predator calls every 10 to 15 minutes. You can add more speakers to cover up to five acres. And the Solar Bird Chase Super Sonic can broadcast distress and predator calls for as many as 22 types of birds, so your store is protected against grackles, pigeons, crows, and many other birds. And unlike ultrasonic systems that emit sounds birds can’t hear, birds definitely respond to Bird Chase Super Sonic’s intimidating sounds.
Plastic Bird Spikes
Bird Spikes won’t allow birds to perch or roost. They’re ideal for keeping birds like grackles off rooflines, signs, parapet walls, lighting fixtures and other elevated structures. More economical than steel spikes, plastic bird spikes come in a variety of colors—including crystal clear, brick red, light grey, brown, black and tan—so they’ll blend in with your store’s color scheme. The best plastic bird spikes are made of unbreakable UV-protected polycarbonate to last for years outdoors. High quality plastic bird spikes feature a flexible base that allows them to bend around curved surfaces. These spiked strips also have pre-drilled holes or glue troughs for easy installation. The spikes come in two-foot sections and 3-, 5- and 7-inch widths to provide wider and wider areas of protection. The bases of the spiked strips are only 1.5 inches wide, which makes them easy to install on narrow surfaces.
Install bird spikes on clean surfaces
Before installing any bird spikes, make sure the surface is clean and dry. Remove any loose rust, peeling paint, bird droppings, feathers and nesting materials. Use commercial disinfecting cleaning agents to keep from being exposed to any of the 60 known airborne diseases carried by birds. If the area is heavily contaminated with bird droppings (wet or dry), use proper eye and respiratory protection.
