Recently, electronic fly swatter appeared, which overcame the shortcomings of pollution of traditional fly swatter, but the cost of fly swatter increased. Second, the fastest: pesticides kill flies. At present, there are two kinds of fly killers on the market: stomach poison and contact poison. ① stomach toxicity. It enters the digestive system through the mouth of worms and plays a toxic role, such as enemies. (2) contact killer. After contact with epidermis or appendages, it seeps into the insect body, or corrodes the wax layer of the insect body, or blocks the valve to kill pests, such as pyrethroids and mineral oil emulsions. Killing flies will pollute the environment at the same time, especially stomach medicine, which is not suitable for food factories with food production and pharmaceutical factories with drug production. Third, all-weather ultraviolet trapping and killing. Flies belong to phototactic animals and are particularly sensitive to ultraviolet rays. Using this feature, humans invented the ultraviolet light trap, and the power grid outside the ultraviolet light can make flies electrocute and die. Advantages: no pollution; You can kill flies day and night. Disadvantages: it will produce sparks and is not suitable for flammable and explosive places. Fourth, the safest: put sticky fly paper. When a fly accidentally hits or falls and stops, it gets stuck and can't move. This method is only suitable for places where there are many flies, and there is no need to strictly kill flies. Fifth, everything comes to nothing-"strengthening the wall and clearing the wild." The longest life span of flies is 15 days. If they don't get food for a long time, they will die soon. Therefore, properly preserving all food and disposing of garbage is a fatal blow to flies. Sixth, the killer-wet rag kills flies. Rags ... >>

Question 2: What smell do flies fear most? When the weather turned warmer and rested for a winter, the annoying mosquitoes that bred a spring began to be arrogant again. After people are bitten by mosquitoes, mosquitoes can be infected with malaria, filariasis, dengue fever, Japanese encephalitis and other diseases besides itching and pain. To deal with mosquitoes, we must know ourselves and know ourselves, and fight every battle. Mosquito's "happiness" and "fear" like mosquitoes to breed in dirty still water and lay eggs and hatch into larvae in these places, so clearing the stagnant water in front of and behind the house is equivalent to ending its "hotbed". Mosquitoes also like to smell sweet wine, or stay in the place where milk stains are left at the bottom of the bottle, so using a sweet wine bottle or bottle with residual stains as a "trap" can often kill mosquitoes. I am afraid of mosquitoes and some flowers, and I am afraid of volatile smells such as cool oil and essential oil. If you put one or two pots of blooming roses, mint, Milan, jasmine and other flowers in the bedroom, or put a few uncovered boxes of cool oil and essential balm, mosquitoes will be confused and run away. Mosquitoes are also afraid of orange light. In summer, they install orange light bulbs indoors or cover them with transparent orange paper, so that mosquitoes will stay away from them. Anti-mosquito tactics Check pots, pans, floor drains, sewers, flowerpots and other places with water, cover them with lids and change the water frequently. Floor drains, sewers and other places to prevent water accumulation, and often spray some pesticides to prevent mosquitoes from entering the living environment. ? Mosquitoes love to hide in radiators, under beds, under tables, corners and other hidden places. You can smoke them with mosquito-repellent incense and kill them one by one. ? Mosquitoes like to lie on the window when it is dark at night, so don't turn on the light at this time, and kill them with a fly swatter or mosquito repellent. ? Pay attention to close the screen window and screen door, and don't leave the door wide open to let mosquitoes in. ? If you are afraid of mosquito bites in the wild at night, you can buy insect repellent such as mosquito bites and apply it to your body for about 4 hours. ? Don't litter cans, mineral water bottles, egg shells and other rubbish that is easy to accumulate water, so as to reduce mosquito breeding grounds. ? If you are on a business trip or don't live for a long time, cover the toilet and clean the water in the sink to prevent mosquitoes from laying eggs. ? Mosquitoes are very sensitive now, and it is difficult to hit them with a fly swatter. Mosquito spray can target mosquitoes and kill them easily. The disadvantage of disc mosquito-repellent incense is that it is polluted and there is a fire hazard when it is used. A lot of smoke is harmful to people's respiratory system. When buying mosquito-repellent incense, you should first choose products made of plant ingredients or low-toxic pyrethroid chemicals. For mosquito-repellent incense, those whose burning time is less than 7 hours according to the national standard can be regarded as unqualified products.

The effective use range of an electric mosquito-repellent incense is generally 15 square meters indoors. In addition, when using, the smell should be fragrant and appropriate, and there should be no sense of * * *, no ash and no open flame. The liquid medicine of liquid mosquito-repellent incense should be free of stratification, crystallization and precipitation, and there should be no obvious smoke and * * * smell when it is used. The user's hands of the electronic mosquito killer cannot touch the high-voltage power grid in the electronic mosquito killer, so the electronic mosquito killer should not be used continuously for a long time. The best mosquito catching effect can be achieved by placing the electronic mosquito killer at the height of 1.5-2 meters. Direct light should be avoided, and the electronic mosquito killer should not be placed in front of the electric fan to avoid airflow interference caused by strong wind. Be careful not to get wet by water and not to play with children during use. Be sure to turn off the power when you don't use it for a long time.

Question 8: How does the fly smell? A fly has no nose, but its sense of smell is very sensitive. It turns out that the fly has a pair of antennae on its head, which are the olfactory receptors of the fly. Each nose has only one nostril connected with the outside world and contains hundreds of olfactory nerve cells. If a smell enters the nostril, these nerves will immediately convert the smell into nerve electrical impulses and transmit them to the brain, and the brain can distinguish substances with different smells according to the different nerve electrical impulses generated by substances with different smells. According to the characteristics and structure of the olfactory organs of flies, scientists connect very fine microelectrodes to the olfactory nerves of flies, amplify the guided neuroelectric signals through electronic circuits and send them to the analyzer, thus replicating a strange small gas analyzer, which is installed in the cockpit of spacecraft to analyze gas components, and is also willing to measure toxic gases in submarines and mines. It is also used to improve computer input devices and gas color image analyzers.

Question 9: What is the smell that flies are afraid of? They are afraid of the pungent smell of vinegar, dried tangerine peel, lemon, onion and garlic.

The smell of food residue and kitchen waste at home attracts flies, and they need to be cleaned up as soon as there are flies. Hengjia's kitchen waste processor can be turned on and crushed to treat kitchen waste, and there is no corruption at home. If it is clean, there will be fewer flies. Remember to open the window every day to keep the air fresh at home.

Question 10: What smell do flies fear most? The most effective way to drive away flies is to open the doors and windows when the weather is warm, and then turn on the electric fan air conditioner to cool down, and the flies fly away by themselves. You'd better catch it with a fan again, and the effect will be better. I often use this method, which is very useful and clean.
