Warehouse Directors Beat Bird Infestations with Ultrasonic Deterrents

Open warehouse doors are a siren call for birds. In a 4,000‑sq‑ft space with 15‑ft ceilings, even the smallest species can find a warm, undisturbed nest.

Wendell Murphy, vice‑president of an Avis rental franchise and air‑freight trucking firm in Lexington, Ky., has spent a decade battling this nuisance.

“For twelve years we tried to keep the birds out of our warehouse at the airport,” Murphy says. “Spring rains and deteriorating insulation made it worse—birds nested wherever the insulation was loose, turning the rafters into an overnight hotel.”

He doesn’t mince words about the mess: droppings contaminate freight, floor surfaces, and equipment, creating costly cleanup and health concerns.

Murphy tried everything from high‑pressure washing to rubber snakes, artificial owls, and even a rifle shot—none of which worked.

His breakthrough came from the Lexington Airport’s facilities manager, an engineer who credited an ultrasonic system for keeping birds out of the passenger check‑in area. The manager recommended Bird‑X Inc.’s QuadBlaster QB‑4.

Following Bird‑X’s instructions to the letter, Murphy’s crew cleared the roosts, repaired insulation with wood strips, and washed the entire building. They then mounted the compact 8‑inch square QB‑4 about 10 feet above the floor, out of reach of dispatchers.

The device emits a high‑frequency tone above the human hearing threshold but one that birds find uncomfortable. After installation, birds landed on the rafters and flew right out.

Today the warehouse is spotless. “No more mess,” Murphy says, noting improved employee morale and reduced health risks from droppings. He estimates the entire project cost under $600—an inexpensive investment compared to potential cleanup and product damage.

Murphy, who has been blind since 1965, also appreciates that the system poses no harm to birds. “I love birds and keep feeders at home,” he adds.

Ray Salvesen, warehouse supervisor for Comdisco Inc. in Chicago, faced a similar challenge. Birds were triggering motion detectors and spoiling customer tours of the facility.

After installing a QB‑4 unit 35 feet up in one dock—alongside nest removal and steel‑wool/mesh screening—birds began to leave. Salvesen noted that the device was even more effective in winter, keeping birds from entering at all. He later installed a second unit in a second dock, finding no need for a third.

Bird infestations threaten cleanliness, safety, and product integrity in warehouses. Ultrasonic deterrents like Bird‑X’s QB‑4 offer a humane, cost‑effective solution that eliminates nesting without harming wildlife. For more information, visit www.bird-x.com.
