1. Predatory natural enemies
Including frogs, dragonflies, spiders, mantis, ants, lizards, geckos, insect eating gadflies and birds. Chicken dung is the breeding of houseflies and barn flies, but there are often ferocious macrocheir mites and marsupials, which will prey on fly eggs and maggots in dung.
2. Parasitic natural enemies
Parasitic wasps such as Apodemus agrarius and wasps often lay their eggs in fly maggots or pupae, and feed on fly maggots and pupae after hatching larvae. It was found that 60.4% of the pupae excavated in spring were invaded by parasitic wasps and died prematurely.
1. Vinegar fly repellent method: spray some pure vinegar indoors, and the flies will avoid it.
2. Orange peel fly repellent method ignites the dried orange peel indoors, which can not only expel flies, but also eliminate indoor odor.

1. Swat the flies with a fly swatter (more primitive)
The effect of this method depends largely on the operator's technology. Advantages: low cost. Disadvantages: the effect of killing flies depends largely on the technology of fly killers; Will produce pollution. The emerging electronic fly swatter overcomes the shortcomings of pollution caused by the traditional fly swatter, but the cost of fly killing has increased.
2. Insecticide fly control (fast)
There are two kinds of fly killing agents on the market: Gastric poison and contact insecticide. ① Stomach poison. It enters its digestive system through the insect's mouth to poison and kill, such as trichlorfon. ② Contact killing agent. After contacting with the epidermis or appendages, it penetrates into the insect body, corrodes the wax layer of the insect body, or blocks the valve to kill pests, such as pyrethroid, mineral oil emulsion, etc. While killing flies, it will pollute the environment, especially gastric poison. It is not suitable for food factories with food production and pharmaceutical factories with drug production.
3. Place sticky paper (safer)
When the fly bumps or falls to rest by mistake, it will be stuck and unable to move. This method is only applicable to places where there are many flies and strict fly control is not required.
4. Fly killing lamp
Day and night UV light trap. Flies belong to phototaxis animals, especially sensitive to ultraviolet light. Using this characteristic, human beings have invented ultraviolet trapping and killing lamp. The power grid outside the ultraviolet lamp can make flies die by electric shock. Advantages: no pollution; It can kill flies day and night. Disadvantages: it will produce sparks and is not suitable for flammable and explosive places.
5. Firm walls and clear fields
Flies live up to 15 days. If they don't get food for a long time, they will die soon. Therefore, keeping all food properly and disposing of garbage is a fatal blow to flies.
