Lifecycle of Flies
Egg
Milky colored with banana-shaped, 1mm in length. It takes 8 to 24 hours for eggs to emerge into the next stage, depend on the temperature and hydration level of the surrounding.
Larvae
Aka maggots, their colors emerge from transparent to pale-whitish, finally in light yellow and then grow into pupae. Larvae are in long, round-shape, with no legs. They are extremely sensitive to bright lights, therefore, they could be found in dark places with poor hygienic condition.
Pupae
Pupae are found in cylinder form, with its color turning from pale to darker, 5 – 8mm in length. The transformation will take place in this stage.
Adult
The pupae will emerge to adult under the process of complete metamorphosis. The wings will be hardened and developed to fly. The life cycle of an adult fly is highly depending on the temperature, moisture level, food and water, for around 2 weeks time. Female flies generally live longer than male for 30 to 60 days.
The harm brought by flies
Flies’ body contains lots of hair; their feet produce sticky secretion. They hunt for food nearby human or animals’ feces, sputum, vomit or even corpse, in which virus or diseases could stuck on their body for spreading, such as Vibrio cholera, typhoid, salmonellosis and other intestinal diseases; moreover, they would stop on food or cutlery while rubbing their body or feet that spread diseases. Another reason why they are such a large virus container is because of their eating habit: flies will split out liquid to dissolve food for intake; also, due to their large intake of food, they deposit feces constantly while eating, which leave diseases in the area. Human will be infected after eating unhygienic food and using unclean cutlery.
How to prevent flies?
Use a bin with lid for garbage handling and clear the bin every day.
Handle and wrap animals’ corpses (such as rats) properly, avoid exposing the corpses in the air.
Use IED in restaurants or for storage places for food.
How to place the right IED?
1. IED should be placed at areas that are most likely to be passed by flies, such as entrance door and living room.
2. IED should be hanged 1.5m higher than the ground.
3. For food production area, IED should be placed at the door, to avoid flies from going in and infecting food.
