DescriptionHouse flies are major carriers of disease and can infest all types of premises. They are attracted to all types of food, including human food, pet food, animal feed, food waste and even faeces. Seeing adult flies is usually the most common sign of activity and a potential problem. Larvae may also be seen as they crawl out of breeding material to pupate. House flies are able to quickly mature from an egg to an adult. They breed in moist decaying vegetable matter eg. in uncovered dustbin or pet food. • Eggs are laid in batches of 120 to 150 and can hatch in 8 – 72 hours. • The larvae of House Flies can take 3 – 60 days to mature. • Pupae matures in 3 – 28 days. Once indoors, house flies can be found resting on walls, floors or ceilings. Outdoors they can be seen on plants, the ground, fences, compost heaps and rubbish bins. At night them they prefer to rest near food sources approx. 5 to 15 feet off the ground.
