On Tuesday (2 August 2016), exterminators took two hours to kill the bees that invaded at least five blocks 271A, B, C, D and 270A at Punggol Walk.
The bees rapidly flew to all 16 floors of the five blocks, with more at the higher floors.
To fend against the bees, some residents wore long sleeved shirts and even raincoats. Others turned off the lights, hoping they would leave.
At about 9pm, exterminators dispatched by the town council arrived and sprayed insecticide. They killed all the bees only at about 11pm.
Several residents were stung but mostly suffered minor injuries.
The exterminator said the bees are not poisonous but some people may suffer allergic reactions from stings, and should visit a doctor if they feel discomfort.
