five methods to repel flies

natural enemies of flies 1. vinegar to repel flies

spray some pure vinegar indoors and flies will stay away.

2. orange peel method

5. the method of driving flies by residual tea

drying residual tea leaves and burning them in a toilet or a gutter can not only drive away mosquitoes and flies, but also remove odor.

Eight tricks to kill flies

First, the most primitive: swat flies to death with a fly swatter. The fly killing effect of this method depends largely on the skill of the operator. Advantages: low cost. Disadvantages: the effect of killing flies depends largely on the technology of killing flies; Will produce pollution. Recently, electronic fly swatter has appeared, which overcomes the shortcomings of pollution caused by traditional fly swatter, but the cost of fly swatter has increased.

second, the fastest: pesticides to kill flies. At present, there are two kinds of fly killers on the market: stomach poison and contact poison. ① stomach poison. It enters its digestive system through insect mouth and plays a toxic role, such as trichlorfon. ② Contact killer. After contact with epidermis or appendages, it penetrates into insect body, or corrodes the wax layer of insect body, or blocks the valve to kill pests, such as pyrethroids and mineral oil emulsion. Killing flies will pollute the environment at the same time, especially stomach poison, which is not suitable for food factories with food production and pharmaceutical factories with drug production.

Third, around-the-clock ultraviolet light traps and kills. Flies belong to phototaxis animals, especially sensitive to ultraviolet rays. Using this characteristic, humans invented the ultraviolet trap lamp, and the power grid outside the ultraviolet lamp can make flies die of electric shock. Advantages: no pollution; Can kill flies day and night. Disadvantages: it will produce sparks and is not suitable for flammable and explosive places.

fourth, the safest: put fly paper. When a fly accidentally hits or falls and stops, it is stuck and cannot move. This method is only applicable to places where there are many flies and there is no need to strictly kill flies.

five, everything is gone-"clear the field". The longest life span of flies is 1.5 days. If they don't get food for a long time, they will die soon. Therefore, keeping all food properly and disposing of garbage is a fatal blow to flies.

six, the trump card-wet rag to kill flies. After throwing the rag with water, the kinetic energy is large, so the range is long, and the coverage area of the rag is large, which increases the hit rate. After a period of practice, the rag thrown by the practitioner will become a fly's nightmare. Flies (21 sheets)

VII. Sticky-catching fly-killing lamp: It combines the characteristics of the third and fourth fly-killing lamps, and uses the most effective lighting frequency of the black light tube to attract flies and other flying insects to fly into the lamp box, which is stuck by the pre-built anti-ultraviolet adhesive board. The whole process is noiseless, odorless, efficient, hidden, safe, non-toxic and pollution-free. It is a widely recognized product in the market now.

Eight, the most environmentally friendly and direct: you can shoot the fly directly by hand. Because the fly's take-off angle is 31 degrees with its plane, the fly is very sensitive to small airflow. Shooting directly from top to bottom often doesn't work, so you can choose the horizontal shooting method. Choose a flat place where flies land, clap your hands and quietly approach the flies. The palms are about 41cm apart, the connecting line between the little fingers of both hands is 4cm-7cm away from the flies, and the midpoint of the connecting line between the palms of both hands is in a vertical line with the flies, so as to ensure the maximum hit rate. When you are ready, quickly close your palms and the flies can be destroyed in your hands. After about 31 practical exercises, you can master this fly killing method. If you use this method for a long time, the hit rate can reach more than 71%. You need to wash your hands and disinfect them in time after killing flies by this method.

fly control measures

methods to control flies can be divided into three categories: physical methods, biological methods and chemical methods. The most effective control measure is the comprehensive use of three methods.

(1) physical methods. The physical method used in livestock and poultry farms is to remove feces in time. Pay attention to the feces and sewage in the dead corner when cleaning, and keep the feces of livestock and poultry dry as much as possible. Do a good job in the cleanliness of livestock and poultry farms and disinfect them regularly. Properly dispose of the removed feces and pull them away or ferment them in time. Waste padding and dead livestock and poultry in livestock and poultry farms should also be properly handled.

(2) biological methods. The biological method to control flies is to cultivate their natural enemies in feces. Natural enemies of flies include beetles, mites and wasps. Under natural conditions, there are fewer natural enemies of flies in feces. Dry livestock manure is beneficial to the development of natural enemies of flies, and we can regularly put natural enemies of flies on the manure of livestock houses.

(3) chemical drug law. Chemicals are the most effective weapon to control flies. Chemical drugs can kill not only adult flies, but also fly eggs and larvae. Chemical drugs are divided into larvicides and adult insecticides.

1. Larvicide: The highly effective larvicide mainly acts on the larval stage in the development of flies, and the effect can only be seen after 2 weeks of application. This kind of insecticide can be sprayed directly on the feces of livestock and poultry or on the ground after removing the feces. At present, the insecticides for killing fly larvae in China are: (1) organophosphorus: fenitrothion, fenthion, malathion and trichlorfon; ⑵ Carbamates: Benzene dichloride; ⑶ Insect growth regulators: there are flufenuron, etc., but they are rarely used in China at present because of the relationship between the insecticidal period and the price. In addition, there are also insecticides for controlling flies through feed at home and abroad, such as ciprofloxacin premix, which is added to feed to control the reproduction of fly larvae in livestock and poultry pens.

2. Insecticide: Insecticide can kill flies quickly, but it is not a standard method to control flies. The commonly used adult insecticides are divided into the following categories: (1) organochlorine: trichloroinsecticidal ester; ⑵ Organophosphorus: fenitrothion (emulsion, wettable powder), fenthion (emulsion, wettable powder) and malathion (emulsion, wettable powder); (3) mixing pyrethroids and carbamates; ⑷ Pyrethroids: deltamethrin (wettable powder).

There are the following methods for applying the insecticide

Apply the insecticide on the staying surface of flies: Apply the insecticide at the place where flies like to stop. Spraying or smearing and painting the pesticide with constant amount, so that the effective components of the pesticide can be uniformly attached to the staying surface of flies according to a certain dose. When flies crawl or perch on the treated surface, they can contact and absorb pesticide poisoning and die.

space spraying: using insecticide aerosol or misting agent to spray in space, so that flies can be poisoned and die directly, which is suitable for quickly killing flies.

poisonous fly rope (rope): Use the habit that houseflies like to stay on rope hangers indoors. Soak cotton rope, hemp rope, etc. in organophosphorus or long-acting pyrethroid pesticides. After the rope is full of liquid medicine, take it out and dry it, and hang it on the roof or ceiling of the pen house.

poison bait: poison bait is a simple, economical, quick-acting and easy method to control flies. Miraculous effects can often occur within a few hours: flies that are resistant to dichlorvos can be controlled by 1.1-1.2% trichlorfon sugar water bait because of different ways of drug entry. In addition to mixed food bait as poison bait, there are liquid poison bait, viscose poison bait and granular poison bait, which can be used in different occasions.

killing rats and flies

when there are rats in the house, people often use rodenticide to kill rats. When the annoying rats stop making trouble, they will forget about killing rats. But after 1-2 weeks, the constant appearance of flies will remind you to look for dead rats quickly. Therefore, after killing rats, we should look for rat carcasses in the corner, pack them in plastic bags and dispose of them.

Finally, smartkiller has a special mosquito and fly catcher. You can have a look if you are interested.
