Flies are the most familiar and disgusting insects for human beings, among which there are three most common flies in China: housefly, golden head fly and Lucilia sericata. Their main harm to people is to spread intestinal infectious diseases: dysentery, typhoid, polio, trachoma, tuberculosis and other pathogens. Secondly, the harassment or bloodsucking characteristics of flies can make people uneasy and upset. Fly breeding reflects the quality of environmental hygiene, affects the development of catering industry and tourism, and also relates to the construction of health city.

Flies are completely metamorphic insects. Their life history can be divided into several stages: eggs, larvae (3 instars), pre-pupae, pupae and adults (segregation, male). Most females lay eggs, but some flies, such as the hemp fly, lay larvae.

Fly control must adhere to the control of breeding organisms (land) as the main method, and adopt a comprehensive control method combining environmental control, physical and chemical control.

1. Environmental prevention and control:

For fly control, environmental control is mainly to control and manage breeding areas, which is the main fundamental measure. To eliminate and dispose of fly breeding materials (including feces, garbage, abandoned animals and plants) and remove the basis on which flies breed, the number of flies is fundamentally controlled. This is the key link in the prevention and control work, and we must pay enough attention to it.

Chemical control:

The killing of flies can be divided into two stages: larval stage and adult stage.

Because of the characteristics of fly larvae and the insecticide resistance of the larvae to insecticides, the killing effect in larval stage is not ideal. Adult fly killing can be treated with a variety of chemicals. However, larval killing and adult killing are still important means in fly control in residential areas. Before the implementation of chemical control, our company technicians know the main species of flies, especially their habits of breeding and activities, find out their weak links, and take effective measures to achieve the purpose of prevention and control. The chemical control methods of flies mainly include detention spraying and quick-acting space spraying.

1. Retention spraying: Retention spraying is spraying long-lasting insecticides in fly habitats, which can obtain longer killing efficacy. Outdoor treatment places include livestock pens, poultry shed ceiling, the inner and inner walls of the top cover of the garbage bin, the glass windows and screen windows of outdoor dry toilets, etc. Indoor treatment places include ceilings, lighting fixtures, filament screens, screen doors and other fly habitats.

2, space quick kill flies: space quick acting fly killing is the use of space spray to kill flies in indoor or outdoor environment in a short time. This method is usually used for killing flies, and it must be equipped with anti fly measures, otherwise it can not be sustained. For example, the "Kangzhuo space spray insecticide" uses ultra low volume spray method to control flies in public places such as hotels and hotels. Installation of fly control facilities and physical control methods

3. Toxic bait to kill flies: It is a simple, quick, economical and easy method to control flies. It can produce miraculous effects in a few hours. Toxic bait can be made into mixed food poison bait, liquid poison bait, viscose poison bait, granular poison bait and so on.

3. Physical prevention and control:

Indoor fly control must adopt physical fly control measures, install fly trapping and killing system, in some unsuitable places for chemical control, set up fly control facilities and physical control methods may be the only effective method.
