Flies belong to the order Diptera and are characterized by having onlt one pair of wings. The hind wings are vestigial and represented by two short organs known as halteres that serve to balance the fly during flight. Most commonly encountered flies have large compoud eyes and usually three simple eyes. Their mouth-parts are of the sponging/lapping or piercing/sucking type.

Life Cycle

All flies undergo complete metamorphosis with egg, larva, pupa, and adult stages in their development. The female fly deposits her eggs in animal waste or moist organic material where the larvae, or "maggots," complete their development, feeding on bacteria associated with their developmental site. When the maggots have completed their development and are ready to undergo the next step in their metamorphosis, they convert their last larval skin into a puparium, a hardened shell within which the pupa develops. Within the puparium, the pupa transforms into an adult fly, which pops off the end of the puparium and emerges. Body fluids pump into the fly's veins, causing the wings to unfold and expand and allowing them to dry and harden so that the adult can fly. The rate of fly development is dependent upon temperature, and under optimal summertime conditions flies may develop from egg to adult in as little as 7 days. Once the female fly has mated, she can lay several batches of eggs, typically containing over 100 eggs each.

Common fly categories found in Hong Kong

• House fly (Musca Domestica)
• Face fly (Musca autumnalis)
• Stable fly (Stomoxys calcitrans)
• Little house fly (Fannia canicularis)
• Garbage fly (especially in the genus Phaenicia)

Communicable diseases

Myiasis

Myiasis is the invasion of living tissue or organs of vertebrates by larvae of fly (maggot)...click for more details

Chrysomya bezziana

Chrysomya bezziana, the Old World Screw-worm Fly, is an obligate parasite of mammals. The site of infection is usually at superficial wounds.

Adult fly feeds on decomposing corpses, decaying matter, excreta and flowers. Adult female only lays eggs on live mammals, depositing approximately 200 eggs at sites of wounding or in body orifices such as the ear and nose. Wounds in the size of a tick bite are sufficient to attract egg-laying. The eggs hatch in 24 hours and the resulting larvae burrow into the host's tissues and feed on the host's dead or living tissue. The larvae are unable to develop in carrion. They leave the wound after 5-7 days and fall to the ground to pupate. Under hot and humid weather, they can complete the life cycle within 15-30 days. Adult flies live on average for 2-3 weeks.

Chrysomya bezziana is an agent of myiasis: the infestation of live vertebrate animals with larvae, which, at least for a certain period, feed on the host's dead or living tissue. Feeding activity of the larvae may cause serious tissue damage, resulting in loss of condition, injury to the skin/hide, secondary invasion and death. Same as other members of this genus, Chrysomya bezziana adults commonly visit faeces and decaying matters. Because of this habit, they, therefore, are mechanical carriers of pathogens.

Management

There is no better defense against flies than a tailor-made treatment plan from Johnson Group

Sanitation Practices
Regular removal (at least once a week) and disposal of organic waste, including dog feces and rotting fruit, reduces the attractiveness of the area to adult flies and limits their breeding sites. Garbage should not be allowed to accumulate and should be placed in plastic bags and held in containers with tight-fitting lids. Garbage should also be placed as far from a building entrance as is practicable. In general, poor exclusion and lack of sanitation are the major contributors to fly problems.

Structure
Flies found inside a building have entered from the outside in almost all cases. Therefore, barriers preventing access to the building are the first line of defense. Cracks around windows and doors where flies may enter should be sealed. Well-fitted screens will also limit their access to buildings.

Bug Defence™ Automated Misting System

Bug Defence™ provides an effective insect mist barrier along the perimeter of protected areas with immediate results. The automated misting system is computer controlled. You can preset your preference time and the system will then spray automatically at the precise rate and time.

Bug Defence™ provides an effective Insect Mist Barrier along the perimeter of protected areas with Immediate results. The Bug DeFence™ Solution is an all-natural, concentrated formulation of essential oils blended with complementary surfactants, and oil-specific synergists. Its gentle lemon scent provides a long-lasting deterrent to biting insects.

The patent concentrated formula is diluted with water before misting. It's a colorless, non-staining liquid that is safe to use around outdoor furniture. It contains no alcohol or toxic chemicals, is non-flammable, and biodegradable.

Developed and further validated through University Entomologists and Independent research facilities, the active ingredient “Geraniol” found within Bug DeFence™ has proven to be the most effective repellent of the over 4000 compounds tested by the University of Florida including Citronella and 10% Deet.

Thermal Fogging Machine and Cold-mist Machine

(Thermal and cold fogging are particularly useful in dealing with large population of fly adults)

Thermal Fogging

Thermal fogging is a space treatment against flying adult. It can reach air spaces in areas obstructed by dense vegetation or other objects. When the flies come into contact with the droplets (usually in 5-30 micron), they will be killed immediately.

Cold-mist Fogging

SOLO® 444 Cold-mist Blower	Fog Master® ULV Fogger

Cold fogging is a space treatment against flying adult. Though It cannot reach air spaces in areas obstructed by dense vegetation or other objects, it is easily to control its distance and coverage, and is more suitable to apply in urban areas. When the flies come into contact with the droplets (usually in 5-30 micron), they will be killed immediately.
