Swarms of bees were seen near Toronto in Canada after a truck spilled crates carrying five million bees on a road. Amid the "bee emergency", police warned drivers to keep their car windows closed, AP reported. The bees were being transported to their wintering location when the accident happened.


Halton Regional Police officials said they received a call around 6:15 am that several bee crates had fallen off of a truck on the Guelph Line, north of Dundas Street in Ontario's Burlington. Constable Ryan Anderson said it was "quite the scene", reported the news agency Associated Press.


"Crates were literally on the road and swarms of bees were flying around. The initial beekeeper that was on scene was apparently stung a few times," police said.


As the bees started to scatter, police warned pedestrians to avoid the area and urged residents and passing motorists to keep their windows closed.


Police also put out a notice on social media regarding the incident, following which a number of beekeepers got in touch with the cops and offered them help. Six to seven beekeepers arrived at the site of the incident soon after the incident to corral the insects.


"There were a lot of flying bees that made even beekeepers in full suits nervous," beekeeper Michael Barber told BBC. He said some beekeepers were also stung.

AP cited data from Canadian Honey Council (a national association of beekeepers) that a colony of honeybees in summer comprised around 50,000 to 80,000 bees.
