Thousands of bees swarmed a small delivery business, driving out employees and customers in fear.

Phone footage captured shows the swarm taking over the entire premises of the SF express delivery service in Maoming in Guangdong, China, on March 27.

Several men could be seen helplessly standing outside the building, with nothing to do but wait for the bees to retreat into a wooden box.

Confused passersby also could not help but stop and stare. Some locals who witnessed the scene reportedly wondered if someone had tried to ship the bees through the delivery service.

However, the owner of the service later clarified the situation, telling local media: 'Bees from the nearby apiary flew into the shop.'

Later, they were led away using a bee box, the owner said.
