84 disinfectant water is fine. Let the bathroom be roughly dry before use, prepare disinfectant according to the requirements, spray it evenly, and once a week, all kinds of small insects will disappear.

Could it be a locust,,, so terrifying,,, no matter what insect is definitely harmful to people, and it looks like a parasite, kill the poison before using water or filter it before drinking, the locust is very afraid of salt, be careful, parasites are very troublesome, and it is also very harmful to the human body.

You can go to the local health department to ask, they still have to take care of this livelihood problem, we don't know the exact situation here, anyway, it's still that sentence, any insect it will definitely not be good for people, it doesn't look like a beneficial insect, there are insects in the water feel so scary, the disease enters from the mouth, be careful

How can it be that long, at most about 2cm.

You'd better put alum in the well, it's gone for a long time.

Don't worry, it's not harmful if you don't drink it directly. In the past, I also had it in the well, probably after a long period of rain, and the other is that the well is too dirty, so you just put alum to purify it and it will be gone, of course, it is better to use it with bleaching powder.

Khan: Actually, I saw this kind of insect when I went back to my hometown. It's in the field. I don't recognize it.

It should be said that "red worms" are more common in river water, well water, and even household tap water. "Red nematode" is also known as silk earthworm, water earthworm, red silk worm, red nematode, etc., and there are snake snakes in the north.

There is no harm to people, it should be grasshoppers and crickets and other grass-eating insects.

There are no insects in the current well, and the wells at the entrance of the factory in the past are also climbed into, because the well is deep and cold and will not give birth to insects, but there are frogs in the well, and the frogs are not afraid of the cold and can hibernate.

Water earthworms. Earthworms mostly live in the sludge on the bank or bottom of the river ditch basin, dense on the surface of the sludge, one end is fixed in the sludge, one end stretches out the sludge to shake in the water, and when it encounters alarm, it immediately retracts into the sludge. Fertility increases as temperatures rise.

Water earthworms have extremely high nutritional value. Before feeding, rinse repeatedly with water. It is the favorite food of goldfish and koi fish and the main food of eel seedlings.

After the tide of the Huangpu River in Shanghai recedes, many earthworms grow in the sludge on the shore, and many people fish every spring and autumn.

Hello, the reasons for the production of black bugs in well water: 1. There are pollution sources (organic nutrients) around: sewage seepage from toilets, pigsties, kitchens and other facilities.

Please change the location of the well and dig a well in a pollution-free place (away from toilets, pigsties, kitchens, graves). 2. Take buckets and various utensils to bring organic matter (rice water, rice soup, meals and other crumbs and juices) into or wash the sewage into the return well, so insects will be born. According to the size of the well, a certain amount of quicklime or sodium chlorate (bleaching powder) can be used to dissipate and put into the well for insecticide and sterilization, and the next day the well is cleaned - emptying the well water, digging up the silt, repairing the well wall and adding the manhole cover, and paying attention to water sanitation in the future (using a special water bucket to take water).

To achieve the above two points, the well water must be clean and free of insects. If there are these insects in the bathroom at home, they are mosquito larvae, they represent bacteria and are not clean. In general, they are present in less clean water, and although they do not have a large impact, they are still uncomfortable.

And in places with a lot of garbage, there are also other larvae that like these environments. Therefore, try to change the indoor water in summer, which can ensure humidity, prevent bacterial breeding, and do not provide a living environment for larvae. Rural areas and some areas where water quality disinfection is not up to standard will find some insects in the storage water, considering that some insects lay eggs in the water tank, the small insects you mentioned are the larvae that have developed to touch the old, it is recommended to clean the water tank thoroughly, use boiling water to scald the tank to kill the eggs, and use disinfectants if necessary.

I also found such insects in the well in my hometown, although I don't usually drink the water from the well, but I still use it for washing clothes and bathing, and I am worried about whether it will be harmful to the human body.

Later, I looked it up on the Internet, and people said that this insect is called a red worm, and its scientific name is water earthworm.

Red nematodes generally live in rivers and sewage, and their reproductive ability increases with the increase of temperature. Experts believe that the nematode is not a parasite, although eating it will not be directly harmful to the human body, but because of its own bacteria and its excrement can cause gastrointestinal discomfort, causing people to have diarrhea, nausea, vomiting and other symptoms.

You described it as mosquito larvae, boiling and drinking.
