What I want to talk about today is the black skin beetle that almost always occurs in the home, a very troublesome worldwide pest.
Body characteristics and living habits
The black beetle is a black oval-shaped small insect with a carapace, very hard, crawling very fast, and the adult can fly.
This kind of bug bites people,However, it is not poisonous and does not secrete venom. Although it is not serious after biting, it only has a small packet, but it looks very disgusting, and it is also harmful to food.
Black beetle is resistant to hunger, cold, and dryness. It can be said to be the "little strong" of the Coleoptera family.
They are generally one generation a year, and the larvae usually cluster in indoors, wardrobes, cracks in floor tiles or dust mustards, and they also appear in flour, beans, cereals and other foods to overwinter .
Most of the larvae seen at home are black beetle larvae. Adults do not eat harmful clothes. Adults fly to the wild to eat nectar, pollen or fungi.
The harm brought by
Black beetle is not a special product of a certain place, and does not exist in different countries and regions. is found all over the world and is a worldwide pest .
It will harm the stored grains and seeds of cereals all over the country. Oilseeds, flours and beans can also be harmed.
According to calculations, the county only damages wheat and corn every year and loses 25,000 kilograms.
and it not only harms all kinds of food, but also harms wool, cotton, silk textiles, fur, raw silk, leather, clothing, nylon, man-made fibers, etc.
In addition,Books, paper, stationery, Chinese medicinal materials, and even some metal products such as plastics and aluminum skins are also affected by this species of pests. It is the most common major pest in homes.
larvae like wood or other hard objects, such as cork, books, plaster, aluminum to dig the pupal chamber, so it often damages the floor, ceiling, wooden shelf, wooden box, bookcase and other items in the home .
How to enter the home?
Many people have questions about the black beetles in their homes. How did these guys get into our home? In fact, there are many channels.
1. Black beetles usually crawl into the home through door and window gaps, wall holes, pipelines, sewers and other places. Some black beetles will also be brought into the home with the goods.
2. Home environment Unventilated places in the home are prone to dampness, and Dermatodes like the humid environment , which also gives them the conditions for reproduction.
3. There is too much debris in the place where the rice is placed. They will overwinter indoors, in the crevices of warehouses or in the sundries , begin to pupate in mid-to-late April of the following year, and continue until early July. Overwintering adults appear from late April to early mid-August. How to destroy
?
(1) If you want to remove this worm, you need to clear the debris in the bottom of the warehouse in time to keep the room clean.The worm-grown food can be thrown away, or it can be exposed to the sun.
(2) Remove nectar plants and weeds around the warehouse to prevent old adult worms.
(3) Use controlled atmosphere control method or aluminum phosphide fumigation method.
In addition, the larvae of the black skin beetle have a pseudo-death nature, and need to be cleaned out of the room in time after being killed.
However, skin beetles are not useless. These earthy brown beetles are considered a major pest in the home.
But for some museums, dermatome beetles are often used by researchers to clean bone specimens, because it is difficult for researchers to clean up small parts of those specimens without damaging the specimens.
But if you see them at home, you still have to destroy them unceremoniously, otherwise the grain, clothing, furniture at home will be the victim...
