Swarms of bees mysteriously appeared at several air bridges at the Philippines main international airport on Thursday, briefly interrupting the boarding of passengers, an airport spokeswoman said.
The bees swarmed around the control panels of six air bridges, the mobile corridors that connect the aircraft to the terminal, preventing the operators from using the equipment, said airport media officer Consuelo Bungag.
"What we did was use the vacuum cleaners to clear them out of the control panels. We also resorted to manual swatting to hasten the process," she said.
Passengers on two domestic flights were forced to board their flights using mobile stairs because of the insects, said Bungag.
Airport authorities are working with the quarantine bureau to find out where the bees could have come from, she added.
