How to prevent bed bugs in winter, and how to prevent bed bugs at home

Bed bugs are a common name for a class of insects with abnormal wing changes, and there are about 30,000 species. Their common feature is that their bodies are flat, large and tiny, and their mouthparts are beak-shaped, suitable for stabbing and sucking. In the suburbs of Beijing, the stink fart insect mainly harms pears, peaches, apples and other fruit trees, in Hunan, the stink fart insect mainly harms rice, the damage rate is generally about 15% to 25%, and the damage rate to the fruit is as high as more than 70%, making the fruit become "lion's mane peach" and "pear pimple", with a bitter taste and loss of edible value.

In urban areas, bed bugs harm willow, elm, mulberry, poplar, acacia, eucommia, paulownia, pomegranate and other greening trees and flowers, they suck the juice of flower buds, petals, leaves, young leaves, fruits, so that the effect of greening and beautification is greatly reduced.

Adults suck the juice of young shoots, shoots, flowers and fruits of plants, causing flower drop, fruit drop and leaf wilting; Adult nymphs emit foul liquid on young leaves, flower spikes and fruits, which also makes the area brown and burned. When a big event occurs, it seriously affects the yield and even causes it to lose its harvest.

Although the harm of orange bugs to fruits is greater, the number of occurrences is generally not much, and manual control should be the mainstay, pay attention to the protection of natural enemies, and use chemical control when necessary.

1) Artificial control.

Adults and nymphs often inhabit the leaves or fruits on the periphery of the canopy in the morning and evening or in rainy weather, and can be killed in the morning or evening when the dew is not dry and inactive. The eggs are mostly laid in the foliar egg mass, which is easy to find, and can be inspected in the orange orchard during the oviposition period of the adult worms in May and August, and the egg mass can be removed in time. However, if a black ring is found under the egg cover, it means that the eggs have been parasitized by parasitic wasps, and should be kept in the field to protect them, so that they can reproduce naturally and increase the number of parasitic wasps in orange orchards.

2) Biological control.

The natural enemies of orange bugs are abundant, and there are known to be yellow ants, parasitic wasps, praying mantises, spiders and so on, which should be protected and utilized.

3) Pharmaceutical prevention and control.

If there are too many insect populations and it is impossible to solve them by manual control, 80% of the enemy can be used.

Use clean white gauze, wrap camphor, dried lemon, pepper, etc., and put them in places where stink bugs are often infested, and you can drive them away, as for killing, spray them with a 1000-fold dilution of emulsion or 800 1000-fold dilution of 90% trichlorfon crystals. If some pine alkali mixture is added to the trichlorfon liquid, the control effect can be improved, and it can be mastered.

The control effect of the first and second instar nymph stage is better.

If you don't move in, you will come in advance to kill the whole insecticide, spray dichlorvos, stuff for three days, and then ventilate to ensure that there will be no insects in your home for n years. It's best to spray more under the floor.

How to get rid of bed bugs.

First, the harm of bed bugs.

There are only two kinds of temperate bed bugs and tropical bed bugs in China, male and female bed bugs and nymphs can suck blood, and the range of activity is generally in the habitat, mainly inhabiting the bed frame, bed board, the four corners of the tent roof, the wall, the table, the chair, the bookshelf and other gaps.

Bed bugs are widely distributed, love human blood, inhabit indoors, reproduce closely related to people, may spread certain diseases, such as relapsing fever, leprosy, plague, tuberculosis, etc., but it has not been confirmed epidemiologically, because bed bugs bite people, hinder sleep, rest and work, and because saliva is injected into the human body during the bite, the bitten part often appears urticaria-like lumps, itching, and can also cause symptoms such as nervousness, insomnia and weakness, so bed bugs are very harmful to the human body.

2. Bed bug control?

1. Environmental control: Transforming the living environment and destroying the breeding and habitat of bed bugs is the key to bed bugs.

2. Physical control: boiling water can kill bed bugs and eggs several times; Manual killing, knocking on bed frames, tables, chairs, picking and killing bed bugs with needles, etc.

3. Chemical control: spray or rub the gaps with 1 2 times thionphos or 1 3 Kaisulin emulsion, or plug the gaps with 1 3 deltamethrin ointment, etc., which can obtain good control effects.

3. Physical killing of bed bugs.

Bed bugs can be killed with drugs, but also by physical methods, under general conditions at home, physical methods can be preferred, relatively small, will not cause household environmental pollution. Here's how:

1) Manual capture: knock on the bed frame, bed board, kang mat, straw mat, etc., shake down and kill the bed bugs, or use needles and wires to pick out the bed bugs in the gaps and kill them.

2) boiling water scalding: bed bugs are not resistant to high temperature, can be scalded to death with boiling water eggs and adults, bed frames, bed boards and other utensils with bed bug breeding can be moved to the outdoors, with the mouth of the kettle filled with boiling water to the gap, slowly move and water, be sure to make the gap reach high temperature, in order to scald the bed bugs and their eggs, for the breeding of bed bugs clothes, mosquito nets, can be soaked in boiling water.

3) Sun exposure: For clothes that cannot be scalded with boiling water, they can be exposed to strong sunlight for 1 4 hours, and turned to make bed bugs die or crawl out due to high temperature.

4) Prevention of dispersion: In rooms with bed bug activities, the relocation (relocation or sale) of luggage, furniture and other items must be strictly inspected and dealt with to prevent the spread of bed bugs from being brought out or brought in.

There may be the following reasons for the appearance of bed bugs indoors, first, the environment is relatively dark and damp, second, the purchased old furniture or old equipment carries bed bugs, third, the indoor hygiene is poor or there is a pile of paper and adhesive paper, and fourth, the quality of the bed board is poor, and there are holes and seams.

Bed bugs prefer to live in dark and damp environments, especially in rooms with low floors that are not exposed to light all year round. It is said that there are two ways to spread bed bugs: active diffusion and passive diffusion, active diffusion refers to the bed bugs themselves looking for a living environment, and passive diffusion generally refers to the bed bugs that are inadvertently brought into the room when relocation.

After removing bed bugs, it is recommended to keep the room dry and ventilated, and bed sheets, bedding and other utensils are exposed to the sun at regular intervals for sterilization.

Through renovation and repair, a home environment that is conducive to human health and not conducive to the breeding and reproduction of bed bugs is created.

Environmental management is a basic measure for the prevention and control of sanitary pests, including bed bugs. It is often said that if the foundation is not strong, the ground will shake, reflecting the importance, longevity and fundamentality of environmental governance. Bed bugs like to hide in various crevices indoors, and repairing or filling gaps in walls, bed board cracks, floors, etc., can reduce the habitat of bed bugs, making it difficult to hide or have nowhere to hide.

It is said that on the basis of doing a good job in environmental management, the combination of other prevention and control measures (such as physical control, chemical control, etc.) can achieve twice the result with half the effort.

Chemical pesticides are used to kill bed bugs. Chemical control has the characteristics of rapid and efficient emergency response, and is an important means to prevent and control bed bugs, especially when the bed bug is seriously infested and the density is high, chemical control should be carried out in time. At present, the insecticides used for bed bug control are mainly Cress insecticides, which are sprayed evenly in bed bug hiding places to effectively and quickly kill bed bugs and their eggs.

If you want to get rid of bed bugs yourself, you must be patient.

The house should be cleaned and sprayed with some disinfectant at home, so that the bed bugs can be completely eliminated.

There are bed bugs in the house, you have to do this to completely ** them, you can spray insect medicine on these damp places every week, which can kill a lot of insect eggs, so that you can completely ** them.

The best way to do this is to pay attention to hygiene.

Are you talking about bed bugs?

You can put mothballs, if you want to put an end to it, you must seize two key periods of spraying, one is the spring recovery activity of overwintering adults (mid and late March), overwintering adults have poor drug resistance, and the first spraying is carried out when a large number of eggs have not yet been laid. Second, before the third instar of nymphs (in mid and late April), the resistance of overwintering adults is reduced to the lowest point, and the newly hatched nymphs are sprayed for the second time when the resistance is poor under the third instar.

Varieties of medicines: 10% high-efficiency chlorchlorfon 2000 times, or 90% crystal trichlorfon 500-800 times, or 80% dichlorvos emulsifiable concentrate 800-1000 times.

Bed bugs, whose scientific name is "Tsubaki elephant", are also called "bugs", insects of the bug family. They are the most diverse group of Hemiptera, with about 5,000 species in the family Elephantidae alone. There are two types of carnivorous and herbivorous species.

Tsubaki elephants are well-known experts in odor gases, they have odor glands, which are located between the dorsal plates of the abdomen when they are larvae, and transfer to the anterior side of the back of the chest when they are adults, and secrete odorous fluid when they are in danger, so as to escape in self-defense, which makes them "notorious".

Common names or aliases: fart bug, stinky big sister, stinky spotted bug, stinky lady, stinky cockroach.

It is commonly found on mulberry trees. aka"Nine spice worms", that is, Hemiptera, heteroptera, melon black bugs of the family Bugidae.

It is a flying blue-black insect the size of a fingernail and resembles a water turtle. In spring and summer, climb on the stems and leaves of crops and suck the slurry with nine spice insect oil, once fried, it is a kind of fragrant and delicious, dispelling disease and prolonging the medicinal food, therefore, it has won the reputation of 'nine spice worms'.

The Dictionary of Traditional Chinese Medicine contains: "Nine spice worms have significant curative effects on nervous stomach diseases, heartache caused by mental depression, soreness and weakness of the waist and knees, impotence, enuresis and other symptoms caused by spleen and kidney yang deficiency. "They are the most diverse group of Hemiptera, with about 5,000 species in the family Elephantidae alone.

Plant a camphor or nightshade tree next to it, which emits chemicals that repel bed bugs and mosquitoes.

It's a stink bug, of course I'm afraid of perfume! I sprayed the toilet water a few times last time, and then it died, haha, vicious
