How to prevent the four evils and what are the four evils

"Four pests" should be flies, mosquitoes, rats, cockroaches, the current social prevention of the four pests mainly rely on the patriotic health campaign, to prevent the four pests, it is necessary to propose solutions to its problems, please refer to the encyclopedia for details.

The four pests are mosquitoes, flies, rats and cockroaches.

On February 12, 1958, the Communist Party of China issued the "Instructions on Eliminating the Four Evils and Stressing Health". It is proposed to complete the task of eradicating flies, mosquitoes, rats and sparrows in 10 years or less. Gradually, the sparrows were "rehabilitated" and replaced by bed bugs.

Later, due to changes in social life, bed bugs were replaced by cockroaches. Therefore, the "four pests" were eventually identified as flies, mosquitoes, rats, and cockroaches.

1. Mosquitoes can transmit malaria, filariasis, dengue fever, yellow fever and other diseases.

2. Flies carry countless bacteria and viruses, and there are dozens of diseases that can be transmitted.

3. Rats not only steal food and destroy buildings and farmland, but also spread plague, epidemic hemorrhagic fever and leptospirosis.

4. Cockroaches not only bite physical objects, damage raw materials, and pollute food, but also spread dysentery, typhoid fever and other diseases.

You can use insecticidal bait to kill cockroaches, environmentally friendly super sticky mouse board to kill rats, 10% insecticidal microemulsion and hot smoke agent for residual spraying, suitable for large-scale use, is the best drug to eliminate the four pests.

If you run into a problem. You can call 0775-2098073 for inquiries.

Common sense of civil servants, "eliminating the four evils", what are the four evils? (

What are the four evils of eradication? Oriental Hanno sanitizes the four pests, and the four pests in the four pests are cockroaches, rats, flies, and mosquitoes.

1. The prevention and control of rodents can be copied and controlled.

Biological control methods and chemical control methods.

2. The prevention and control of flies is mainly to do a good job in the harmless treatment of garbage and remove all kinds of breeding sites; Doors and windows are equipped with fly nets and other facilities.

3. The key to the prevention and control of cockroaches is to prevent the invasion of cockroaches, to wipe the cracks and plug the holes, to do a good job in indoor hygiene, to eliminate the cockroach habitat, and to cut off food and water sources.

4. People remove stagnant water indoors and courtyards to eradicate the mosquito breeding environment.

1. Eliminate rats.

Rats can not only steal food, bite bad clothes, furniture, bite wires and cause fires, but also can spread violent and acute infectious diseases, such as plague, endemic hemorrhagic fever, leptospirosis, salmonellosis (food poisoning) and so on, endangering people's health and life safety.

How to get rid of rats? The most common methods are as follows: 1. Drug rodent extermination, and the rodent drugs that are now being used are dichloride, killing it, bromadiolone, rodenticide, etc., which can produce a certain degree of drug resistance in rodents.

Therefore, it must be used interchangeably. 2. Tools to kill rats can be used with rat clips, wooden box closures, and stone slabs. 3. Biological rodent extermination, mobilize the masses to raise cats, and protect the natural enemies of rats (owls).

2. Exterminate flies.

Flies can transmit more than 30 diseases. Common diseases include: hepatitis A, paracholera, typhoid, paratyphoid, dysentery and polio.

To eradicate flies, three opportunities must be seized. In winter, it is necessary to get rid of overwintering adult flies and fly pupae as soon as possible. In the spring, it is necessary to pay close attention to the early killing of the first generation of flies, and strictly control and eliminate the breeding sites, so that the flies do not have the opportunity to breed.

In summer and autumn, in the peak season of flies, we should vigorously eliminate adult flies, eliminate breeding sites, and do a good job of environmental sanitation, so that flies do not have places to lay eggs and maggots. At the same time, in the active season of flies (April to October), it can also be manually pounced or poisoned with various drugs.

3. Eradicate mosquitoes.

Mosquitoes not only bite people, but also affect people's sleep and rest, and spread malaria, Japanese encephalitis, filariasis, etc. Therefore, if there are more mosquitoes, some insect-borne infectious diseases will increase, endangering people's health and affecting production, work and study. How to get rid of mosquitoes?

First of all, it is necessary to vigorously carry out a patriotic public health campaign, fully mobilize the masses to do a good job of environmental sanitation, fill up sewage pits, dredge yin and yang ditches, and eradicate weeds at the water's edge. Secondly, it is necessary to spray insecticide frequently to eliminate adult mosquitoes both indoors and outdoors. In addition, it is necessary to eradicate the larvae (i.e., larvae), either by hand-fishing, by pouring some kerosene into a large number of sewage puddles, or by killing the larvae with dichlorvos.

Fourth, eliminate cockroaches.

Cockroaches, commonly known as oil thieves, carry a variety of pathogenic bacteria on their bodies and are a vector for spreading intestinal infectious diseases. In addition, it can also gnaw on clothing, books and other utensils, and people hate it.

How to get rid of cockroaches?

Kill with drugs, such as argon, cidiachlorvos, fly cockine and other drugs; Always keep the room clean and hygienic, especially the kitchen, so that the tableware, cupboards, and clothes are often washed and kept tidy; Artificial catch.

The harm of the four evils to people is very large, and the four evils may be encountered in daily life, so the four evils must be eliminated in time

The key to rodent extermination is to improve rodent prevention facilities indoors and outdoors, plug rat holes and harden the ground.

1. Remove debris indoors and outdoors, do a good job of environmental hygiene, block rat holes, and harden the ground. So that rodents have no hiding habitat. Windows and all ventilation holes should be fitted with barbed wire in square centimeters; Sewers and gutters should be fitted with barbed wire in square centimeters.

2. The holes and damaged parts of the building should be filled with cement concrete.

3. The doors and windows of the room with food sources should be closed, and the barbed wire of the above-mentioned mesh should be installed, and the lower edge of the door should be inlaid with a zinc iron plate 60 cm high.

4. Set up artificial rat holes in hidden places around buildings and garbage passages and put poison baits for a long time.

The key to mosquito control is to remove and treat all kinds of stagnant water.

1 Outdoor altars, tanks, tanks and bonsai, rockeries, pools, watering buckets (pots) and tanks, sewage ditches, sewage pits, sewers, underground water valve boxes, septic tanks, tires and other stagnant water are the main breeding grounds for mosquitoes. To do it:

2. Do not store any stagnant water indoors and outdoors, and all kinds of containers should be placed with their mouths facing down to prevent water accumulation.

3. Change the water storage containers for watering flowers and pets, bonsai, rockeries, rich bamboo, kimchi jars, etc. every 4-6 days.

4. Remove all kinds of indoor and outdoor wastes (including tires), and dredge the water in sewage ditches, drainage ditches and gutters, as well as houses and shed eaves in a timely manner.

The key to fly control is to control and remove litter.

Garbage passages, garbage cans, garbage plots, garbage heaps and droppings in houses are the main breeding grounds for flies to lay eggs, feed and grow and develop, and these fly breeding grounds must be completely removed.

The key to cockroach control is to control and manage food, water and clogged crevices.

1. Store food and animal feed, remove residual food and used utensils, swill feet, etc., in time to eliminate cockroach food.

2. Remove garbage and debris at any time, repair damaged houses and facilities in time, plug gaps, and minimize the habitat of cockroaches. 3. Control the water source, keep the kitchen and toilet clean, hygienic and dry environment, and use cockroach bait if necessary.

The four pests are mosquitoes, flies, rats, and cockroaches. Mosquitoes and flies can transmit a variety of diseases, rats can not only spread diseases, but also steal food, destroy buildings and farmland, cockroaches also spread diseases, but also bite real objects, damage raw materials, and contaminate food.

The four pests were originally flies, mosquitoes, mice, and sparrows, and later, sparrows were "rehabilitated" and replaced by bed bugs, and then later, bed bugs were replaced by cockroaches, and the "four pests" were finally designated as flies, mosquitoes, mice, and cockroaches.

There are 252 kinds of pathogens such as germs, viruses, spirochetes, and rickettsials found in the world, and 114 kinds of "four pests" can be carried.

The existence of the "four pests" is not mainly the spread of epidemics, but the harassment they bring, the density of the "four pests", or the indirect indicators of whether the environment is dirty or not, reflecting the depth and breadth of a city's comprehensive improvement.

Sparrows should be removed and should not be protected.
