methods of killing flies in restaurants: installing a fly trap, spraying in space and separating flies.

1. Installing a fly trap

There are four stages to kill flies: eggs, larvae, pupae and adults. The first three stages mainly live in breeding grounds and breeding grounds. A large number of wastes, such as food residues, excreta, secretions, production leftovers and so on, are good breeding grounds for flies.

Therefore, regular care and cleaning of the living environment is very effective for reducing flies. Set a fly trap behind the kitchen or in the kitchen waste dump, use rotten fish as bait, trap adult flies and then kill them with pesticides.

2. Space spraying

Space spraying is used in the open air, and pesticides are used for space spraying, so that flies can be poisoned and die directly when they get in contact with the mist particles, which can kill flies quickly. For restaurants, it can be sprayed at the front and rear positions. The drugs sprayed in space are highly toxic. As a food occasion, the restaurant should be sprayed as far away from the kitchen where guests eat, so as to ensure food insurance.

3. Cut off flies

Killing flies indoors or outdoors, spraying pesticides in space, so that the flies directly touch the mist particles of chemicals and die of poisoning, which can quickly kill flies. Indoor spraying can use less dangerous pesticides such as aqua or deodorized kerosene dosage form, while organophosphorus pesticides can be used in garbage dumps and in the field.

Installing screen doors and screens at the doors and windows of restaurants can effectively avoid the invasion of foreign flies. In addition, a blower is installed at the inclined position of the outlet wind of the restaurant, which can form an air curtain or duct after working, and can also effectively drive away flies.

Habits and hazards

Flies are omnivorous flies, and they can eat various substances, such as human food, secretions and excretions of human beings and livestock and poultry, kitchen residues and other garbage, and plant juices. After the housefly is full, it can excrete feces at a short interval (a few minutes).

Due to frequent vomiting and defecation, more water loss and frequent feeding, flies eat, spit and discharge on the breeding materials, causing serious pollution. In livestock and poultry farms, feed and drinking utensils are often polluted by it.

flies can spread 51 kinds of diseases, among which important diseases affecting livestock and poultry breeding, such as avian influenza, Newcastle disease, foot-and-mouth disease, swine fever, Pasteurella multocida, avian colibacillosis and coccidiosis, can accelerate the spread of epidemic diseases when diseases break out.
