How many ways can you kill flies? There are many ways to kill flies, the most thorough way is to control and deal with the breeding of flies; The most effective way is to beat with flies; The most commonly used method is a fly trap; In addition, there are fly bait, fly rope, fly paper, spraying pesticides and other methods.
What is the best way to kill flies? Fly is a completely deformed insect, which goes through three stages in its life: egg, larva (maggot) and pupa. So the best way to kill flies is to deal with substances suitable for flies to breed. If the garbage is bagged (the bag should be intact and the bag mouth should be tightly tied), do not litter or urinate anywhere, and properly handle the pet feces.
Adopt comprehensive flight control measures;
Since the advent of chemical pesticides, remarkable results have been achieved in killing pests, but many drug-resistant populations have emerged due to repeated use. At the same time, pesticides also pollute the environment and do harm to people, livestock and natural enemies. However, at this stage, chemical control is still an indispensable and important measure for fly control on the basis of environmental management. This is also a more convenient and economical measure. Especially under special circumstances (such as floods and earthquakes) or during the epidemic period of intestinal infectious diseases. Can reduce the density of adult flies as soon as possible.
Choose the opportunity, occasion, drug types, dosage forms, dosage, application equipment and methods of chemical control. It should also be considered in combination with specific conditions in order to achieve better benefits. Chemical control can be divided into two aspects: for larvae and adults;
(1) Kill fly larvae; The larval stage of flies is generally concentrated and easy to find and use. The first instar larvae are very sensitive, but their life span is short and their heads are small, so it is best to apply pesticides in the early stage of 2-3 instars. At the end of 3rd instar, the killing effect was poor. In addition, the characteristics of evil creatures also closely affect the efficacy of pesticides. If pesticides are used for larvae in dung piles and garbage dumps, it must be considered that pesticides can fully act on worms. When the manure is thick, it is appropriate to use low concentration and large dose, and when the manure is thin, it is appropriate to use high concentration and small dose. Chemical insecticides used in larval stage are easy to induce drug resistance. Especially when the same chemical insecticide is used to control larvae and adults, the resistance will be faster.
The World Health Organization recommends the use of insecticides to kill fly larvae;
Organophosphorus: diazinon, bromophosphazene, dimethoate, troponin phosphate, butachlor, fenthion, malathion, methyl thiophosphate and trichlorfon.
Carbamates: benzene dichloride and light-resistant pyrethroids. In addition, insect growth regulators, such as flufenoxuron, have a good effect on various resistant fly populations. According to China's situation, there are the following chemical pesticides for fruit treatment:
Diazin, fenitrothion, fenthion, malathion, trichlorfon and mirex are all produced, but there are few insect growth regulators in China at present because of the relationship between insecticidal period and price.
In addition, maggots that breed in relatively limited places in small containers can be properly treated by simple methods such as boiling water or soaking in cold water, in addition to applying a small amount of drugs.
(2) Killing adult flies: Under normal circumstances, killing adult flies is mostly carried out indoors, and the safety of using sanitary pesticides should be emphasized.
1. Pay attention to the safety of indoor pesticides: the use of sanitary pesticides is mostly in the living environment, even in the environment where people have conditions or are in close contact with people, which directly or indirectly relates to people's health. Although most sanitary pesticides belong to low toxicity category, some of them belong to poisoning category, and the main pesticides belong to neurotoxicity category, no matter how low toxicity, they are still toxic. Some people say that some products (pesticides) are harmless. Long-term exposure to low-toxic pesticides will be harmful. Some are sticky and irritating to the skin, so when using pesticides, we must pay attention to rational use and scientific use.
When using pesticides indoors, we should choose low-toxic pesticides with qualified quality; There are no expired drugs. When spraying pesticides indoors, operators should wear protective clothing, hats and gloves. Deal with the leakage of medicine from the sprayer in time, and no one is allowed in the room when spraying medicine. When spraying medicine in the canteen or kitchen, put away the food and tableware. When using aerosol, don't use it in places with heat sources and open flames. Don't point at people when spraying. Don't spray too much, because after the fly comes into contact with the drug, it can only be knocked down and killed after the drug enters the body and works.
There are several ways to control adult flies chemically.
2. Pesticide application on fly-stopping surface: it is used outdoors in breeding ground, surrounding and nearby vegetation surfaces, indoors, doors, windows, walls, ceilings over 2 meters, barns, stables and other places where domestic flies like to stop. Pesticides with residual effect and contact killing effect are sprayed or smeared quantitatively, so that the effective components of pesticides are uniformly attached to the staying surface of flies according to a certain dose. When flies crawl or perch on the treated surface, they will be poisoned by absorbing pesticides.
The effect of pesticide application on the retention surface depends on the residue period of pesticide itself and the uniformity of spraying. Generally, the surface with strong water absorption should use lower concentration and higher dosage, and the surface with poor water absorption should use higher concentration and lower dosage.
Insecticides used to prevent and control adult flies from staying on the surface are as follows:
1) organochlorine: triclosan (7504) emulsion.
2) Organic phosphorus: diazinon, (emulsion, wettable powder), fenthion (emulsion, wettable powder), malathion (emulsion, wettable powder), phoxim (emulsion), fenpropathrin (10% mirex, wettable powder).
3) Carbamate: Kuaikang (80% metoclopramide mixture: wettable powder)
Bailidan (20% propoxur EC)
4) Mix pyrethroid and carbamate: polymethalin (wettable powder)
5) Pyrethroids: Kaisuling (2.5% deltamethrin wettable powder) and Dyke (deltamethrin suspending agent).
Fendouna (5% cis-cypermethrin wettable powder)
Weihai Jing (5% beta-cypermethrin wettable powder)
Aikening (10% cypermethrin wettable powder)
Mirex (cypermethrin suspension concentrate)
Shafik (10% cyfluthrin wettable powder)
Baichongsha (12.5% beta-cypermethrin SC)
3, space spraying: indoor and outdoor, using insecticidal aerosol or mist agent for space spraying, so that flies are directly contaminated with drug mist particles and poisoned to death, suitable for indoor or outdoor rapid killing of flies. In short, using the same insecticide to control drug-resistant houseflies, space spraying is more effective than residual spraying, but the cost is higher, and organophosphorus pesticides (such as dichlorvos, malathion, fenitrothion, phoxim). Carbamates (such as propoxur) and pyrethroids (such as pyrethroids and permethrin) have better effects. When necessary, the two drugs can be mixed or used in combination with synergist to obtain better results.
Spraying method: manual sprayer, cold aerosol can be used indoors, and hot aerosol generator can be used widely outdoors. Ultra-low volume spraying is a special method of space spraying. It can be sprayed with high-concentration oil or emulsifiable concentrate in a large area, with quick effect and low dosage.
The World Health Organization recommends using some pyrethroids to kill flies outdoors in the form of ultra-low volume or hot smoke, which can achieve good results, but it is expensive and has short residual effect, and can only be used in special circumstances, such as when all adult flies must be quickly eliminated during the epidemic of intestinal diseases.
(1) Spraying insecticides outdoors to control adult flies:
A organophosphorus: phoxim (EC), cartap (EC), malathion (oil), dichlorvos (emulsion) and dichlorvos (light diesel oil preparation).
B pyrethroids: permethrin (oil), permethrin (emulsion), fenvalerate (pyrethroid, emulsion), cypermethrin (suspension emulsion),
(2) spraying insecticide indoors to control adult flies;
Organophosphorus; Phoxim (emulsion)
Carbamates: fenobucarb (emulsion) and propoxur (emulsion).
Pyrethroids: permethrin (oil), (aerosol)
Permethrin (aerosol), pententhrin (oil)
Fenvalerate (pyrethroid) (spray)
In rooms and restaurants with complete fly prevention facilities such as screen doors and screens, 1-2 flies occasionally enter, and try to beat them with flies. If it is difficult to hit them because of the high level of the room, it is best to use an ejector or aerosol and a manual aerosol can at this time and spray 1-2 times at the flies.
4. Poison fly rope (rope): Take advantage of the habit that houseflies like to stay indoors on the rope hanger. Soak cotton rope, hemp rope, etc. Organophosphorus or long-acting pyrethroid insecticides. After filling the rope with medicine, take it out to dry and hang it indoors or on the roof or ceiling of the poultry house.
Insecticides that can be used to soak poison ropes are:
Fenthion 10-25% EC, malathion 10-25% EC, propoxur 10-20% EC, permethrin 1- 1.25% EC, deltamethrin/.
In addition, fenitrothion, diazinon, dimethoate and pyramidate can also be used. Adding a little brown sugar or other attractants to the poisonous fly rope during the production process can also increase the killing effect.
5. Poison bait: Poison bait is a simple, economical, quick-acting and easy-to-use method to kill flies. Miraculous effects can often occur within a few hours: the flies that are resistant to dichlorvos after residual spraying can be controlled with 0. 1-0.2% trichlorfon sugar water bait due to different ways of drug entry. In addition to mixed bait, there are liquid bait, viscose bait and granular bait. , can be used in different occasions.
Insecticides used for poison bait include mirex, diazinon, dichlorvos, trichlorfon, dimethoate, dermatophytes, malathion, naloxone, methyl thiophosphate, propoxur, bendiwei and so on.
Commonly used poison bait formula:
0.2% trichlorfon sugar solution (sugar content: 10%)
0.5% of trichlorfon grains and corn grains, and 0.2% of trichlorfon fish viscera.
0. 1% trichlorfon sugar solution (sugar content is 10%), 0.05% fenthion granules,
0. 1% propoxur sugar solution (sugar content is 10%).
Yingnandan is often used as fly bait, which can achieve very good results. However, the drug is highly toxic, and it is forbidden to be used in other places except the garbage yard under the supervision of professionals. Besides food bait, poison bait has other attractants.
