A family went on holiday to return to these scattered over the floor. They called us suspecting a rat infestation. The small brown objects are in fact fly pupae. They had forgot to empty the kitchen bin and house fly had bred in the decomposing waste. When the maggots had finished feeding they leave the organic waste in the bin to pupate where it is dry. All that was required on this call was sweeping them outside for the birds.
