Is it possible to use dust soap from lice and nits

Попробуем разобраться, насколько эффективным и безопасным является применение дустового мыла для борьбы со вшами...

Dust soap is truly one of the most effective means of lice. This is evidenced by the testimonies of those who did not hesitate to apply it, and real scientific research on the effectiveness of its main component (DDT). However, the use of such soap is associated with a serious danger that the main component of soap represents for a person, and in particular for a child.

Even in the second half of the last century, before the appearance of innumerable innocuous insecticides and the means based on them, the soap from lice was almost the only really reliable alternative to "grandfather" folk recipes based on kerosene and vinegar. Indeed, it cost a piece of soap penny, and lice allowed to withdraw from one time, and even in fairly complex and neglected cases.

"My mother always poisoned the lice with dust, and I showed them to their children. It is inexpensive and absolutely reliable: the head is soaped, hides under a bag, washed off in half an hour and washed with shampoo. The smell, of course, is terrible, but no nits and no lice survive after that. "

Nevertheless, today dust soap is considered the property of history: it is used in extremely rare cases by residents of especially remote areas. The reason for this - in its side effects, which caused the worldwide ban of this remedy.

What are the properties of dusty soap?

Dust Soap: composition, action, effectiveness against lice

Dust soap is, in fact, a simple household soap in which DDT, one of the most famous insecticides, is added at a certain concentration. It is DDT in the common people called dust, and thanks to this soap itself got its name.

Дустовое мыло является, по сути, ничем иным, как привычным для всех хозяйственным мылом, куда добавлен ДДТ

ДДТ опасен тем, что может накапливаться в тканях организма

Do not confuse dust and tar soap. The first has no cosmetic properties and is intended only for the destruction of parasites. The second, on the contrary, improves the condition of the scalp and hair, but the lice are very weak.

Не нужно путать дустовое мыло и дегтярное, так как они имеют совершенно разную природу действующего вещества.

With the help of DDT, for several decades, very different insects-parasites and pests-have been exterminated very successfully. At one time its use even began to resemble mania: DDT was poured everywhere, wherever possible, even when there was no obvious need for it.

Еще несколько десятилетий назад ДДТ активно применялся в сельском хозяйстве для борьбы с насекомыми-вредителями.

It is interesting

According to experts, DDT saved at least 10 million people for the history of its application. Only in India it was able to eliminate the epidemic of malaria (it processed water reservoirs - natural reservoirs of reproduction of malarial mosquitoes): then 5 million inhabitants of villages and rural areas were threatened. Similar situations took place in Greece and Italy. In addition, it was at the expense of DDT that the Green Revolution became a reality - before its use, pests destroyed a much larger portion of the crop than after the beginning of treatment with dust fields and gardens.

In the 60s of the last century, doctors found that the accumulation of DDT in the body causes serious intoxication, sometimes with a fatal outcome. Even before that, environmentalists were sounding the alarm because of the mass mortality of birds feeding on damp fields treated. Finally, in the late 1960s, the use of DDT in human pest control was banned in many countries around the world, and the louse-dense was, in fact, outlawed.

На сегодняшний день дуст практически не применяется не только против вшей, но даже и в аграрной сфере.

Nevertheless, dust soap against lice is very effective. DDT is an insecticide of contact action, capable of penetrating into the body of the parasite through the chitinous covers of its body. This means that if soap lather is thoroughly soaped over the entire head or other parasitic parietal parts of the body - so that it surely gets on every insect - all the parasites can be destroyed in one treatment.

At the same time, all nits will die. It should be noted that even many modern means against lice do not possess such high efficiency.

On a note

The larva of an ordinary meatfly, several times larger than the size and weight of a louse, perishes from the exposure to the surface of its body of one millionth part of a milligram of dust.

Concentration of dust in the soap is sufficient to not worry about the amount applied to the head means: if all the hair will be under the foam, this will be quite enough.

"We tried a few means from lice with the whole family. I washed my head with Pedilin, my daughter was treated with Nittifor, my husband, like a stern man, was washing his soap with soap. The result: dust soap is beyond competition. I think the nits have died before the bag was put on the head. The stink, of course, unbearable, my husband then got sick all night, but the remedy works flawlessly. Pedilin is also good, but the nits had to be combed separately. "

Dangers and side effects when using dust soap

It is believed that a person is lethal with a dose of more than 300 mg of DDT per kilogram of body weight when taken in. Roughly speaking, for poisoning at one time you need to swallow about 20 grams of DDT - that's a lot.

However, the dust has a very unpleasant quality - it constantly accumulates in the tissues and is practically not excreted from the body. This means that even if the dose is not received immediately, but in parts, the result will be the same.

To serious poisoning, sometimes with instant vomiting, already results in a dose of 16 mg / kg. Lesser amounts cause usually moderate intoxication.

In this case, DDT, getting on the skin, does not cause any particular harm. However, when using dust to lice, the substance can penetrate into the eyes, nose, scratches at the site of the bites on the head during the treatment, which will still lead to penetration of the insecticide into the human body.


"Our son brought lice from a children's camp. It's okay, of course, but it's unpleasant. Grandmother in the old manner washed his head with dusty soap, and the next morning I had to take Tema to the hospital - he was very vomiting and vomiting, his whole head was sprinkled. The doctor looked at us as if she were insane, she says that the dust against lice and nits is like throwing gasoline on your head and burning it. Lied Theme under a dropper for three days, then a week away at home, and then we just shaved it and forgot about lice. "

Lydia, Pskov

It is believed that DDT, accumulating in the body, can lead to various mutagenic disorders, the emergence of malignant tumors, weakened immunity, the development of diseases of the nervous system and brain, poisoning and death of the fetus in pregnant women. There is no direct evidence for such assumptions due to the termination of the use of the dust, but there is a prerequisite for believing that these fears are not groundless.

Symptoms of poisoning with dust are:

  • nausea and vomiting
  • weakness in muscles
  • headache
  • shortness of breath, and asthmatics - exacerbation of the disease
  • an allergic reaction with rashes on the skin.

If after application of a dust soap at least some of these symptoms have appeared, the patient should necessarily be shown to the doctor. Doing lavage of the stomach and drinking activated charcoal in these cases is useless.

There are also contraindications to another property - soap itself very much dries the skin and can lead to irritations. Therefore, people with dry skin do not use dust soap better.

If the decision is made: how correctly to apply dust soap

But if the dust soap against lice is still decided to use (highly not recommended), it should be applied in accordance with the following rules:

  • the handler should wear a respirator, goggles and rubber gloves, soap the soap and soap the patient's head Перед обработкой головы от вшей дустовым мылом необходимо запастись перчатками и респиратором.
  • the patient should always sit with closed eyes and mouth
  • after applying soap on his head, he puts on a rubber cap or bag, which is pulled under the hairline by an elastic band
  • the foam is kept on the head for half an hour (at the first sensations of pricking, burning, itching it needs to be washed off) and the head is thoroughly washed with a simple shampoo several times
  • even damp hair combed by a frequent comb (it is good to use special pediculicidal combs) to remove dead lice and nits.

It is worth remembering about the very unpleasant smell of dust: after the removal of lice, its "fragrance" can persist for quite a long time.

Dust soap can not be used frequently or regularly. The Dust destroys lice and nits already at the first treatment, but if suddenly after that the parasites on the head still remain, they should be removed by any other means.

Tar soap, aerosols and shampoos: an overview of alternative means

If possible, dust soap is better replaced with safer and no less reliable means of lice. For example, the following options are good for this:

  • Shampoo Pedilin and Aerosol Para-Plus - these drugs destroy both lice and nits, but they are not toxic to humans. Шампунь Педилин является гораздо более безопасной альтернативой дустовому мылу
  • Sprays from lice Paranit and Nyuda - they do not destroy nits , but are completely safe and are recommended for use in children. Спрей от вшей Нюда
  • Pediculicidal ridges - they have to comb their heads for several days in a row, but they are deprived of any contraindications and side effects.

Гребни для вычесывания вшей и гнид абсолютно безопасны для здоровья.

And, finally, there is always the opportunity to just shave off the hair, infected with lice. This is the most effective, simple, safe and affordable way to fight. If the infection occurred in the summer, shaving the hair will help to restore the healthy condition of the scalp more quickly.
