Flies can regularly be found in homes and businesses across New Zealand.
Some species are more common than others and are attracted to different environments suited to their natural habits and lifecycle.
Knowing about the size, habits, seasonality and lifecycle of different fly species, can help to identify the most effective prevention and fly control methods.
FACT: On average, the adult housefly will live for around 30 days. They go through a complete four-stage cycle that consists of egg, larva, pupa and adult stages.
House 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.
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
Bluebottle flies (also known as Blow fly) can often be seen hovering around dustbins. These scavengers are attracted to pet faeces and dead animals and as such are known carriers of disease.
Their name originates from their iridescent colours that are similar to coloured bottles.
Cluster flies are commonly found in quiet, undisturbed parts of your home, such as attics and wall voids. They require warm places to hibernate over winter.
You may see a large group of cluster flies around a window, as they are attracted to the light on sunny winter days.
Adult sand flies can be a real biting nuisance. They live on sandy riverbanks with an open habitat free of shading trees.
Females prefer to lay their eggs in damp soil or in the water.
Drain flies are often associated with sewage beds, where larvae feed on sludge–like organic matter. They are also known by a variety of names; drain fly, sewage fly and moth fly are a few examples.
Lacewings are considered an important predator of mealybugs in both greenhouses and interior plantscapes.
They also feed on (among others) several species of aphids, spider mites (especially red mites), thrips, whiteflies, small caterpillars and beetle larvae.
Adults are active fliers, particularly during the evening and at night. They have a characteristic fluttering flight.
They feed on pollen and also need nectar or honeydew as food before laying eggs.
Lacewings are often used as a biological integrated insect control program.
