There is a brilliant way to catch birds. When sparrows and pigeons were plagued by the Central Balu Cafe, the landlady had a whim and bought a "bird-driving amplifier" to take turns to play the sounds that the birds feared most, driving away 70% of the wild birds.

Before the diners left, the birds in the trees were already eyeing the food on the table. The "Fusheng Food Pavilion" on the ground floor of Block 11A in Ballu King had been harassed by wild birds for more than a year.

Recently, however, there are suddenly fewer wild birds there, but there are more bizarre "calls".

It turned out that these strange noises came from a "bird driving amplifier". The sounds played by the loudspeaker included the majestic cry of eagles, the fierce barking of dogs, the crackling of firecrackers, and the mournful cry of birds arrested.

Zheng Yutong, 41, the owner of the coffee shop, revealed in an interview that she began to test the "audio bird driving method" in the three coffee shops she operated four months ago, and the results were particularly satisfactory to her.

Zheng Yutong has been plagued by bird infestation since he took over the operation of the coffee shop a year and a half ago. She said that there are thick trees near the coffee shop, and groups of sparrows, starlings and pigeons often gather on the trees, staring covetously at the food of diners.

"at first, the birds would wait for the diners to leave before they swarmed down and pecked. Later, the birds became more and more daring and began to fly down to grab their food when the diners were not looking. After eating the food, the birds will leave feces everywhere in the coffee shop, making the environment very unsanitary. "

Zheng Yutong said that she has tried many ways to drive birds, including placing iron flowers, trying lasers, placing CDs, and so on, but to no avail.

She said that she accidentally saw someone driving birds with sound abroad, so she imported four special bird expelling amplifiers from China and the United States to try.

"after the amplifier was installed, it soon achieved results. About 70% of the birds were afraid of these sounds and were afraid to go near the coffee shop."
