The content border of the handwritten newspaper for eradicating the four pests

The four pests are flies, mosquitoes, rats and cockroaches. Although science and technology are highly developed today, eliminating the four pests is still a very serious problem. Here are some common prevention and control methods, I hope they will be useful to everyone. 1. Guidelines for preventing and controlling flies 1. Preventing flies Flies have very diverse feeding habits and often lay eggs on garbage, feces and rotting animals and plants. The life cycle of a fly includes eggs, maggots, pupae and adult flies. Under suitable conditions, such as the common house fly, it takes 20 days to complete the entire life cycle at 16°C, but only takes 10-12 days at 30°C. And the number of adult flies only accounts for 15% of them. Therefore, the first task of fly prevention is to control the breeding places and breeding organisms of flies: (1) Remove all kinds of garbage, feces and rotten animals and plants promptly and thoroughly, and keep them clean Clean sanitary environment; (2) Install intact screen doors and screen windows, which can not only ensure good indoor ventilation, but also effectively prevent flies from entering the room. Commercial places usually have a large flow of people, so it is necessary to install professional anti-insect air curtains in commonly used ventilation channels to block the invasion of flies. The professional anti-insect air curtain machine is highly targeted, and in terms of wind speed and air outlet angle, the wind speed is 17 meters/second, which is a breakthrough improvement compared to ordinary air curtain machines and has a remarkable anti-fly effect. 2. Fly control: Fly swatters and aerosol cans are commonly used to control flies at home. Although they are convenient to use, they are less effective in killing flies. Fly sticky strips can better catch flies and are very suitable for indoor use. The fly trap is safe, environmentally friendly, convenient, strong and durable. It uses fly pheromones to lure flies and achieve excellent fly killing effects. This method is both economical and efficient, and is suitable for a variety of environments. The fly killers used in commercial places and their facilities should be pesticides that have been registered and allowed to be used in the country. Residual spraying using insecticides with residual and contact effects can effectively kill flies staying on the sprayed surface. If there are too many flies indoors, you can use professional fumigators and fumigants to fumigate and kill flies. This will kill flies quickly, effectively, conveniently, safely and environmentally. The stick-catching fly killing lamp uses the ultraviolet light source that is most effective at attracting flies and uses viscose to stick flies. This avoids the use of high-voltage electricity to kill flies in traditional fly killing lamps, causing fly corpse fragments to pollute the environment. This method is safe and effective. It is an indispensable method for daily fly control and is suitable for various indoor places. 3. Maintenance The control of flies must be persistent for a long time. The first task is to strengthen the control and management of breeding areas to prevent flies from breeding and breeding. (1) Maintain good and hygienic environmental sanitation; (2) Clean up garbage, feces and decaying matter in a timely manner to block the growth and development of flies; (3) Regularly inspect the sticky fly killing lamps, fly traps and fly strips Based on the inspection results, we will judge the fly control effect in the area based on the fly catching situation, and formulate specific control plans for the next step based on reality. 2. Mosquito Killing 1. Anti-mosquito: Mosquitoes cannot live without water, did you know? Mosquitoes need to spend about 7 days in water from eggs to adults. How to effectively prevent mosquitoes? The first step is to control mosquito breeding areas. We must check and remove environments with standing water (such as small containers, potting trays, air conditioning trays, kitchen and bathroom floor drains, etc.) at least once a week. Secondly, there must be necessary anti-mosquito facilities. Intact screen doors and screen windows not only ensure good ventilation of the place, but also more effectively prevent mosquitoes from entering the room. Mosquito nets are the safest anti-mosquito tool. If you have a baby or your living environment has serious mosquito problems, use a mosquito net soaked with an soaking agent that is harmless to the human body to achieve a more significant anti-mosquito effect. Installing professional anti-insect air curtains at the entrances of commercial places and facilities can very effectively prevent the invasion of mosquitoes. Professional insect-proof air curtains are highly targeted, and are qualitatively improved compared to ordinary air curtains in terms of wind speed and air outlet angle. The wind speed is 17 meters/second, and the anti-mosquito effect is immediate. 2. Mosquito control: Commonly used methods for killing mosquitoes at home mainly include mosquito coils, mosquito killer lamps and aerosol cans. However, each of these methods has its own shortcomings: some are slow to act, some have poor potency, and some are not comprehensive enough. How can we kill mosquitoes safely, environmentally friendly, conveniently, quickly and effectively? At present, the best way to kill mosquitoes is to fumigate and kill mosquitoes. Use professional fumigators and fumigants to kill mosquitoes. It only takes 9 minutes to kill mosquitoes. It is safe and effective. The mosquito killers used in commercial places and their facilities should be pesticides that have been registered and allowed to be used in the country. Residual spraying using insecticides with residual and contact effects can effectively kill mosquitoes staying on the sprayed surface. If there are too many mosquitoes indoors, the most effective way to kill them is fumigation. Mosquito killer lamps can be installed indoors or in entrance and exit passages to achieve better control effects.

Large stagnant water, rivers, rice fields and reservoirs are also breeding places for mosquitoes. In these places, pesticides recommended by the World Health Organization for drinking water can be used, which are safe and effective. 3. Maintenance: Inspection and monitoring are long-term tasks in mosquito control, so as to clearly understand the distribution, degree of harm and prevention effect of mosquitoes. According to the growth and development rules of mosquitoes, inspection and monitoring should be carried out on a 7-day cycle. The breeding characteristics of mosquitoes determine that the focus of this work is to check the stagnant water to see if there is mosquito breeding. Once a breeding problem is discovered, preventive measures should be taken immediately. 3. Guidance on rat prevention and control 1. Rat prevention Rats do many harms and can transmit many diseases such as: plague, epidemic hemorrhagic fever, leptospirosis, murine typhus, etc. Rats have a wide range of habitats, ranging from the walls of houses, under floors, on ceilings, in heating ditches and sewers, to the mezzanines of trains and ships; from suitcases and drawers to stacks of firewood and hay, they can hide and inhabit. Rats have great breeding potential, so doing a good job of preventing rats is the key to eliminating rat infestations. How to scientifically prevent rats? (1) Collect food and garbage, tidy up all kinds of utensils and sundries, check and clean suitcases, wardrobes, books, shoes and hats regularly, keep the surrounding environment clean and tidy, and cut off the food source of rats; (2) Clean up Destroy and eliminate the habitats of rats by randomly stacking items and hidden spaces such as the bottom of furniture; (3) Narrow gaps and harden the ground: Use cement to repair holes and cracks in ceilings, walls, and floors, and connect doors and floors, doors, and doors. Repair the gap between the window and the window sill so that the gap is no larger than 0.6 cm to prevent house mice from escaping; (4) Make a rat-proof door: install a 30-50 cm high iron sheet on the lower edge of the door in important places to prevent rats from chewing it door panel, or add an iron gate with a height of 60 cm, and ensure that the distance between the bottom and the ground is less than 6 mm, so as to keep mice out; (5) Install anti-rat fences in the trench, and the distance between the fences shall not exceed 12 mm. 2. Rodent control: There are many methods to control rats, generally physical and chemical control are used. Chemical rodent control, also known as pharmaceutical rodent control, uses poisonous bait to kill rats, which is effective and easy to use. However, you must purchase rodent-killing poison baits from regular channels and strictly follow the instructions for use to avoid unnecessary harm. Physical rodent control method: also known as instrumental rodent control method, it has been used for a long time and has many application methods. Place special baited mousetraps (such as mousetraps, mouse cages) and sticky mouseboards in areas where mice often hang out to trap mice. For commercial places or facilities with a large flow of people, these appliances must be placed in extremely hidden places that are out of reach of people to avoid harm to people. Imported mouse traps are extremely safe and will not cause personal injury. The viscosity of the sticky mouse board is the key to catching mice, so you should pay special attention when purchasing to avoid affecting the effect of killing mice. 3. Maintenance: Rat control work must be carried out for a long time, and regular inspection is the key. (1) Regularly inspect repaired holes, cracks and other facilities to ensure they are intact; (2) Check whether there are new mouse hiding places or intrusion passages in the indoor and surrounding environment, and repair them in a timely manner; (3) Frequent inspections cannot Seal the area with sticky boards and mousetraps, and clean up the captured mice in a timely manner; (4) Understand the situation of mice, use mouse-catching tools alternately, and adjust their placement to make mice difficult to detect and ensure efficient rodent control. 4. Guidelines for preventing cockroaches 1. Prevent cockroaches Perhaps inadvertently, your home has become a paradise for cockroaches. As we all know, cockroaches have an astonishing reproduction speed, reproductive ability and environmental adaptability, and their feeding habits are very diverse. It likes dark, warm and moist places. Cockroaches are everywhere, and their main hiding places are: (1) The narrow spaces between various cabinets and hanging wall cabinets placed close to the wall and inside the cabinets; (2) The base of the refrigerator and freezer, and the small chamber of the compressor , power switch box, etc.; (3) Gaps around kitchen countertops, cracks in cutting boards, etc.; (4) Food boxes, debris piles, grain piles, under sinks, cracked tile seams, etc.; (5) Under bathroom sinks gaps, gaps between mirrors and walls, clothing cabinets, bedside tables, table drawers, etc., computer cases, keyboards, phones, under carpets; (6) drainage ditches, wall holes for wires and water pipes, floor drains, etc.

Scientific prevention of cockroaches: (1) Cockroaches are initially brought in by goods, including food, daily necessities, etc., so the items brought in must be carefully checked; (2) Sprinkle repellent powder at the door to prevent cockroaches elsewhere. (3) Smooth wall cracks, cracks and gaps around pipe holes, and move unmoved items regularly; (4) Replace floor drains with strong partitioning effects; (5) Places where food and goods are stored should be regularly and thoroughly cleaned Clean up thoroughly to prevent the remaining cockroaches from spreading. 2. Cockroach control: Aerosol cans are commonly used to kill cockroaches at home, but the effectiveness of cockroach control is affected due to the hidden nature of cockroach habitat. The residual spraying method is commonly used in commercial places, but this method is not environmentally friendly and safe. The most widely used method at present is the bait method, which is prepared with food that cockroaches like so that they will be poisoned and die after eating it. Among them, gel bait is widely used in homes and commercial places because of its environmental protection, safety and convenience. Cockroach killing powder not only kills cockroaches, but also repels and blocks cockroach invasion. If the cockroach damage is serious, you can use the fumigation method. Use professional fumigators and fumigants to fumigate the room. It can quickly penetrate the gaps and kill cockroaches comprehensively. It only takes 40 minutes to kill 90% of cockroaches. It is necessary to rationally select and match cockroach control methods according to the specific situation. Only comprehensive application can achieve more effective prevention and control. 3. Maintenance: The harm of cockroaches to humans will appear at any time, because they can spread more than 40 diseases such as dysentery and typhoid fever. Therefore, daily inspection and monitoring of cockroaches is particularly important. (1) Check in real time whether the gaps everywhere have been smoothed; (2) Frequently check the items stacked indoors, inside cabinets, drawers, wall cracks, corners, around heated objects, and in damp places; (3) Put away sticky paper In a location susceptible to cockroach infestation (with food, water, warm place). According to the inspection situation, we can grasp the dynamics of cockroaches and effectively eliminate cockroaches.
