Johnson Group Flies Control Service

Flies are the most common pest problem and is the hardest one to solve. It is one of the most common disease transmission media as well. They often grew from filth, such as feces and rotten meat, very visible in premises such as wet markets and garbage collection points. They will cause pollutions everywhere they go, like our food and water sources. If the problem was overlooked, it could lead to infection of digestive system or skin, or even causing major health problems.

To deal with the outstanding adaptability and reproductivity of lies, an thorough upgrade of the environmental hygiene is needed. Specific measures are required to prevent flies infestation, so as to truly resolve the problem. Our specialist will come up with a tailor-made plan according to clients’ environment and needs. And we prioritize non-chemical resolutions. Apart from pest control services, we also provide professional cleaning and sanitizing services to improve general hygiene.

Chemical Treatment

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.

If the pest problem was severe, Johnson Group will deploy the one-shot aerosol insecticide to kill all the common pests including flies, mosquitoes, cockroaches etc. And then carry out other measures to improve the overall hygiene.

Characteristics of Flies

Flies belong to the order Diptera and are characterized by having only 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 compound eyes and usually three simple eyes. Their mouth-parts are of the sponging/lapping or piercing/sucking type.

Johnson Group - overview flies

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.

Fly control is accomplished by searching out their bredding places and then improve the sanitation practices. Many materials currently in use are physical in origin and are highly specific for flies, with little or no effect on other organisms.

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.

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.

Communicable diseases


Myiasis is the invasion of living tissue or organs of vertebrates by larvae of fly (maggot). Feeding activity of the larvae may cause serious tissue damage, often accompanied by putrid discharge and ulceration, resulting in loss of function, injury to the skin, secondary bacterial invasion and death.

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 feces and decaying matters. Because of this habit, they, therefore, are mechanical carriers of pathogens.
