Fruit flies, or Drosophila melanogaster, are often found around our food waste bins as they feed on rotting fruit which gradually produces alcohol.

Almost every residential area is plagued by overflowing bins.

"People were going to the wagons to put the rubbish in themselves, which you shouldn't do, and emptying wheelie bins in the road."

Mr Armstrong, who lives in Grangetown, said the rodents had been a particular problem near his home for the past two years since communal rubbish bins overflowed onto the floor.

In some parts of the second city, residents said bins had not been collected since mid-February.
