Recently, the people of Jiefangqiao Road, surnamed Li, have always been plagued by a kind of bug.
"A small black worm that doesn't fly fast, doesn't have many numbers, and is easy to shoot to death." But the first day it was shot dead, and the next day it would appear again, out of nowhere. Mr. Lee said he had heard that the bug was called a "sewer insect." "From the sewers, that's not disgusting!"
<h1>It's annoying! </h1>
There are always small black worms in the bathroom at home
Mr. Li said that in recent times, the frequency of this small black worm is very high. "Of course, we are rarely at home during the day, and when we come back to take a shower at night, we find small black worms in the bathroom and the bathroom."
The small black worm has rounded wings, and if you look closely, the wings are still a little transparent.
Every time he saw the little black worm, Mr. Li would shoot him to death one by one. "The number of them appears every day is not much, three or five."
However, after shooting every day, there will be small black worms the next day. "The doors and windows are so well closed, I don't know where they came from."
<h1>Find answers</h1>
"I heard people say 'sewer insects'"
"My friend said that he had encountered this kind of bug in my family, and later he specifically checked it and said it was a 'sewer insect.'"
"How dirty the sewers are!" This bug flew up from the sewer, and it wasn't disgusting. "Mr. Li told reporters that he would like to know how to eradicate this insect." If one day it flies out and falls into the soup in the dish, it is not too dirty! ”
<h1>Experts explain their doubts</h1>
This little black bug is called a moth midge
The reporter rushed to Mr. Li's home and photographed the two small black worms that he had deliberately kept.
Entomology expert Zhu Shude said that this small black worm, scientific name moth midge, is a sanitary pest.
It is reported that the adult insect of this insect is not harmful in itself, but it may carry some germs; moreover, the larvae or eggs of moth midges will "parasitize" in the human body once they enter the human body. Therefore, although the bugs are small, they should also pay attention to prevention.
Zhu Shude said that moths and midges fly slowly, but it is best not to shoot them directly with their hands, and they can choose to spray mosquito sprays.
At the same time, moth midge larvae prefer moist, dirty, dark environments and generally do survive on sewer walls. And, because the larvae are small, they are difficult to spot.
"One is to ensure that the bathroom and bath are clean, conditional, and dry, as far as possible to control the environment of breeding moths; the second is to clean up the garbage in the bathroom and the bath in time; the third is to clean up the floor drain in time and spray some insecticides regularly." Zhu Shude said that although moths are more disgusting, they fly slowly, and one flight is not too far, and there is no need to be afraid to see it.
In addition, moth midges, although prefer humid environments, are not tolerant to flooding. Therefore, there are sewer pipes at home, preferably sewer pipes with curves, so that there is water in the bends, which can also effectively control moths and midges.
