What is the reason why there is a stinky big sister in the house?

There may be several reasons why there is a smelly big sister in the house:

1.Environmental factors: March to September is the breeding season of the elephant, which may be conducive to the breeding of the elephant due to the humid climate, the small number of people, and the lack of air circulation.

2.Hygienic factors: Leather or adhesive paper on the bed board is convenient for the breeding of Tsubaki elephants, and it is best not to have anything like paper paper on the bed board.

3.Carrying: Relocation or new workers bring in, do a good job of insect prevention before entering the room, and wash or expose items in time.

4.Bed board quality: In order to save money, many factories buy poor quality bed boards, and the holes and gaps are obvious, which brings convenient breeding conditions to the Tsubaki elephant to hide.

To sum up, the stinky sister may enter the house because of the combination of various factors such as environment, hygiene, foreign carrying, and the quality of the bed board. In order to prevent the appearance of the stinky sister, you can take corresponding precautions, such as keeping the room clean and ventilated, avoiding contact with the places where the stinky sister may be hiding, and buying the best bed boards.

Every autumn, it is also the active period of the stinky sister, especially if there are trees or flowers near the room, there will be a large number of stinky sisters entering the room along the gap around the screen window. It is recommended to eliminate it in time after it is found, and replace it directly if the sealing strip on the window does not work.

If there is a stinky sister at home, it is because the house is close to trees and flowers, and the doors and windows are not tightly closed, so the stinky sister ran in. The general activity time of the stinky big sister is from the turn of spring and summer to almost winter, and in winter it will be completely hidden, and it will come out again in spring.

The stinky eldest sister has a dark brown body color; The dorsal posterior side of the head bears a pair of tiny orange-yellow, or orange-brown longitudinal spots, and the terminal of the last segment of the antennae 2 3 is partly orange-yellow or orange-brown, partly, the individual is in the first.

There is still a section of orange-yellow or orange-brown spots in the second and third segments. There is a sharp spike on the outer edge of the dorsal plate of the prothorax,** with a transverse arc orange-yellow or orange-brown fine spot.

Stinky Sister's life history:

According to the annual observation, in the south-central Hebei region, the annual generation of tea winged Tsubaki, all the adults who emerge early, the eggs laid before mid-June, hatched, the nymphs can emerge into the first generation of adults, and can lay eggs, and then emerge into the overwintering generation (second generation) adults by the nymphs.

However, only one generation of eggs laid after mid-June can occur, that is, the adult that emerges is the overwintering generation. Macular Tsubaki occurs one generation a year. Both overwinter indoors as adults.

There are two reasons why there is a stinky big sister in the house, which are as follows:

Reason 1: Poor hygiene at home, garbage is not disposed of in time, or the ground is damp, and the indoor ventilation conditions are all reasons that cause the stinky sister to enter the house.

Reason 2: The change of seasons caused the stinky sister to enter the house. Annual.

In April and May, the stinky elder sister breeds in large numbers and will often run to the house.

The stinky sister's handling method is stupid

1. If you find a stinky sister at home, first check whether there are cracks in the doors and windows at home. If there is, seal it up. It is better to put a gauze on the window to prevent it from creeping in.

2. Mix the laundry detergent with water into a thick liquid and sprinkle it on the place where the stinky sister often appears. The house should be kept clean, and an unclean environment is easy to attract the eldest sister.

3. Close the doors and windows, spray the house with pesticides, people and livestock leave, and come back a few hours later, you will always find some surprises on the ground. If there are fruit trees outside the house, it is easy to attract the eldest sister, especially apple trees and jujube trees. If the tree is not big, you can shake it, and after the stinky sister falls from the tree, you can trample it to death with your feet.

4. If there is a large number of stinky sisters in the farmland orchards, you can go to the market to buy special powders to kill the stinky sisters, mix them into a concentrated liquid and spray them. The stumps of some trees and the withered yellow plants in the field stalks gather to burn them, and they can also be partially wintered.

Bed bugs generally live in groups, and can live with clothes and luggage, mainly inhabiting the bed frame, the corners of the tent, the walls, the ceiling, the table, the chair, the bookshelf, the bedding, the straw mat, the bed mat, etc., and the back of the paste wallpaper, where there are often a lot of brown feces.

Bed bugs are afraid of light and are mostly active at night, with the peak of activity being between 3 and 5 a.m. Bed bugs are agile and alert, they can suck people's blood without people noticing, and when they suck blood, if the human body moves slightly, they will stop sucking blood, crawl away and hide. It is difficult to attract bed bugs, and even if some methods are used to attract them, they can only kill some of them, not all of them.

Bed bug extermination methods.

1. Eliminate bed bugs through drugs. The medicine can be selected as a musticide powder. Jiebing Sa must be a powder of medicine, in a small bottle.

The method of use is very simple, spray the medicine directly in the corner where the bed bugs appear or the corner of the wall and the corner of the furniture, the more evenly sprayed when spreading, the better, do not sprinkle in a pile.

After spreading the medicine, the bed bug crawls on top of the medicine, sticks to its feet, or when it is close, it comes into contact with the medicine, so that the bed bug will be excited, and will go back to the nest to bite its companion, and then slowly die. Generally, all bed bugs can be eliminated in about 10 days after use.

2. Keep the room clean and tidy, remove debris, plug the gaps in the bed board that are easy to breed bed bugs, plug them with lime or putty, pay attention to personal hygiene, wash clothes, mosquito nets, bed sheets, etc. frequently to control the breeding of bed bugs.

3. For bed frames, bed boards and other utensils that have bed bugs breeding, they can be moved outdoors, and the mouth of the kettle filled with boiling water is aimed at the gap, and the gap must be moved slowly to water, so that the gap reaches a high temperature to scald the bed bugs and eggs.

4. Soak clothes, mosquito nets, bed sheets, and pillows with bed bugs; For clothes that cannot be scalded with boiling water, you can soak them in disinfectant powder or laundry detergent for half an hour, clean these items, and then put them in the sun.

5. Quilts, mattresses, and bed boards can be exposed to strong sunlight for several hours, and often turned over, so that bed bugs can escape due to high temperature, so as to clean up bed bugs.

The scientific name of the stinky eldest sister is "Tsubaki Elephant", also called "bug". There is a stinky gland opening behind the stinky big sister's body, and when it encounters an enemy, it emits a stinky gas, and it is also called "fart bug", "stinky girl", etc.

According to the data, Tsubaki elephant is a common name for a class of insects with abnormal wing changes, about 30,000 species, of which more than 90 are pests. 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 stinky elder sister mainly harms pears, peaches, apples and other fruit trees, the harm rate is generally about 15 to 25, and the damage rate to the fruit is as high as 70 or more, making the fruit become "monkey's peache" and "pear pimple", with a bitter taste and loss of edible value.

In urban areas, the stinky elder sister harms 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, and fruits, so that the effect of greening and beautification is greatly reduced.

Forest protection experts taught the citizens a few tricks to treat the stinky sister, and concentrated on hunting and killing the stinky sister during the winter; In early spring, measures such as plugging tree holes and scraping old bark were taken; In summer, at noon, gently shake the trunk of the tree with your hands to kill the stinky sister who has landed in time; In addition, it is necessary to prevent and control the stinky eldest sister during the nymph period, because during this period, the stinky eldest sister can only crawl and cannot fly.

At present, the Forestry and Biocontrol Center has entered the experimental stage of biological control by using the natural enemy of the stinky sister, the Tsubaki Xianggou egg wasp. The field investigation showed that the parasitism rate of Tsubaki eggs was relatively high, the average parasitism rate of Tsubaki eggs was 47 22, and the parasitism rate of Tsubaki eggs was 30 56 on average, which was the natural nemesis of the stinky sister.

Make good relationships and think about good times.

It's not realistic to completely eliminate the eggs, and when you see it, take the tape, stick the side outward, clump together, stick to it, take a few layers of paper and wrap it to death, and then throw it downstairs in the trash can, don't put it at home.
