Chemical formula of dust. DDT (dichlorodiphenyl trichloromethylmethane)

All means are good against bedbugs. This common truth is a strict statement for those who have already tried many drugs and methods, trying to get rid of these insects. Taking into account the peculiarities of the life of bedbugs and their reproduction, it is not so easy to remove them from the living quarters.

Ordinary dust is a chemical insecticide that residents of the former Soviet Union... At one time, everything was poisoned with this substance, from fleas on pets to the processing of crops, the destruction of mosquitoes, the treatment of head and pubic lice. Today we hear little about dust, the shelves of hardware stores are flooded with all kinds of chemicals, mostly made in China with a dubious efficiency rating.

We have set ourselves the goal of reminding the inhabitants of our country about what dust is, tell about its main historical merits, and also look into its chemical formula in order to understand how effective the remedy is against domestic bugs. And of course, nothing will support our theoretical research more than the reviews of people who have used dust in practice against bedbugs.

What is dust?

Dust is an insecticide of chemical origin, the more accurate name of which is DDT. Dost this tool began to be called due to its powder form, as it is known in English "dust" is translated as "dust, powder". Dust is a colorless, crystalline, tasteless and almost odorless organochlorine agent known for its high insecticidal properties. DDT is produced only in the form of dry powder additives, which allow protecting the active working substance from decomposition. It is these additives that give the dust that grayish-blue color and specific smell.

“We bought the dust, hoping for its effectiveness, and we really regretted it. The smell is unbearable, irritating this powder, which had to be poured everywhere. It is scary to get poisoned, not to mention the children and the dog who had to be sent to grandmother. Yes, there are fewer bugs, but all have not disappeared, because it is impossible to sprinkle everything in the world. Now we will buy something sprayable and not so toxic to people. " Anna.

DDT is now found in many commercial insecticides... Due to its hydrophilic molecule, DDT can be used in almost all forms - emulsifiable concentrates, water-soluble powders, granules, aerosols, fumigants, vaporizers and aqueous solutions.

DDT was first synthesized in 1874, but the insecticidal effects of the agent were discovered much later by the Swiss chemist Paul Hermann Müller in 1939. Dost received widespread publicity for helping control the spread of malaria and typhoid fever among civilians and military personnel during the second half of World War II. DDT does not possess disinfectant properties, but it can be used to suppress the huge spread of body lice, head lice and mosquitoes, which are known to be carriers of typhoid and malaria, respectively.

After the war, DDT herds were available for use as an agricultural insecticide and production and use were increased accordingly. Müller was awarded the Nobel Prize in Physiology or Medicine for the discovery of the high effectiveness of DDT as a contact poison against certain arthropods in 1948.

However, the ascent to Olympus was short-lived. In 1962, the book "Silent Spring" by the American biologist Rachel Carson, which was published, turned upside down international relationship to DDT. This directory unveiled the environmental impact of the indiscriminate spraying of DDT in the United States and challenged the release logic a large number potentially dangerous chemical substances into the environment without a sufficient understanding of their impact on the environment or human health.

In addition, the author argued that DDT and other pesticides are capable of causing cancer and that their agricultural use poses a threat to wildlife, especially birds. The publication of the book was a landmark event for the environmental movement, which led to a great public outcry, which ultimately, in 1972, ended with the ban on agricultural use of DDT in the United States.

The worldwide bans were subsequently formalized under the auspices of the Stockholm Convention on Persistent Organic Pollutants, but the limited use of dust for the control of insect disease vectors continues to this day and remains controversial. DDT remains an effective tool in reducing human mortality from malaria, which in itself is considered a higher priority than protection environment and concern for the health of birds.

In Russia, dust today continues to be actively used against body and household insects, but its use in the agricultural sector is very limited. Here DDT is replaced by pyrethroids - plant-based insecticides, which are considered more loyal to warm-blooded creatures.

Effects on human health

Of course, it was not in vain that the noise was raised against the active use of DDT in any of its forms, including in the form of powder - dust. In addition to the harmful effects on the environment, DDT interferes with the functionality of the human endocrine system, but as for the carcinogenic effect, although much has been said and written about this in its time, detailed studies have not been carried out.

DDT is classified as a "moderately toxic" substance under the programs in different countries, including Russia. It is considered "moderately dangerous" according to the classification of the World Health Organization (WHO). This means that in pure form DDT is not available in regular hardware stores today. The right to use it belongs to persons who have undergone training and internship, as well as employees of organizations engaged in professional destruction of insects.

“We noticed one bug crawling out from under the baseboard. We went to the neighbors - it turned out that they were poisoning. We bought dust and filled up all the cracks. The smell was terribly unpleasant, in the first days we could not spend the night at home, then it faded a little and we ventilated constantly. But we must pay tribute - the bugs did not migrate to us, we did not notice any more of these pests, and none of our households had bites. So in some cases it is quite possible to apply. " Ildar

Among other things, DDT is characterized by the likelihood of chronic poisoning by it. Such an effect can be achieved with long-term and regular toxic effects of DDT on the human body. DDT, like other organochlorine compounds, has xenoestrogenic activity, due to the fact that the molecules of dust and female sex hormones are chemically quite similar. As a result, DDT is able to induce corresponding hormonal responses in animals and humans. In general, such a poisonous effect of DDT is expressed in the following violations:

• premature birth;
• properties destroying the endocrine reproductive system;
• decreased sperm quality;
• pathology of menstruation;
• change in the duration and quality of lactation.

Applying bug dust

In addition to all of the above, it is worth noting that modern dust, in the general sense, may not contain pure DDT in its composition due to its limited use. sanitary standards... And in those packages that are sold, the so-called "Chinese dust from bedbugs", there is anything you want, but only DDT. Therefore, it is better to refuse such a proposal from Chinese underground manufactures right away, otherwise you can make it so that there will be no one left in the living room except bedbugs and cockroaches.

Therefore, when purchasing dust, it is better to trust domestic manufacturer, moreover, it is better to directly purchase the goods in organizations that not only distribute insecticides, but also themselves are engaged in persecution of domestic insects. Here there is the highest probability of acquiring a truly high-quality drug.

It is allowed to use dust in the form of an aqueous solution, however, before pouring the powder into water, you should read the instructions - the mixture may contain substances that are not soluble in water. The best option the use of dust against bedbugs will be its use in the form of a dry powder. For those who decide to treat their bedroom with dust on their own, you should know the following.

Dust is a dry powder and the less moisture it contains, the more effective and more its insecticidal properties. Therefore, it is necessary to process initially dry surfaces, and protect your respiratory organs with a respirator. Inhalation of dry particles of chemistry necessarily stimulates their absorption on the mucous membranes and can provoke irritation and even general poisoning of the body.

Before processing, you need to take out in an airtight plastic bags all things that can be taken off and picked up. Fall into this category - linens, stuffed animals, electronics, contents of boxes, cabinets and so on. It must be remembered that these things may contain adult bugs and their eggs. The bags will prevent them from getting out as they move around the apartment and infecting other rooms. All things must be additionally treated with temperature or chemistry, allowing the processing of fabrics and plastic.

At the time of processing, there should be no pets, birds and aquarium fish in the room. For the last two categories, it will be enough to inhale a few particles of dry dust to start irreversible changes in their body.

As already noted, personal protective equipment is required - gloves, goggles, mask or respirator. Clothing should not allow the penetration of dust on the bare areas of the skin.

Shown before processing wet cleaning all surfaces that need to be sprinkled with dust, this will increase the insecticidal effect.

Pets must not be allowed into the room after treatment.

Precautionary measures

True dust has a specific odor that can disrupt night sleep, and the smallest particles of chemistry, can cause an allergic reaction. Therefore, with the appearance of pain in the eyes, lacrimation, sneezing, headache, nausea and other signs of a violation of the general condition, it is necessary to interrupt contact with dust as soon as possible and seek medical help.

The effectiveness of dust from bedbugs

In general, DDT is very effective against any insect. It is not for nothing that the Nobel Prize was awarded for this discovery. However, the reviews that can be found on the Internet are contradictory, which we associate with different chemical composition funds distributed under the brand name "Dust", as well as - the frivolity of manufacturers.

Dust - description of the drug

Dust is an insecticidal preparation that is effective against bedbugs, cockroaches, flies, ants and fleas. On average, a package of this powder is designed for 10 m2. Due to its physiological properties, dust is resistant to temperature changes and works well in dusty places. After cleaning, micro-particles of powder remain on the treated surfaces, which continue to act for several months.

The composition of this drug may vary depending on the brand of the manufacturer. To attract buyers and increase the price, flavors and dyes are added to the powder, however, this does not affect the quality of the dust. Pure dusty powder is based on:

• Cypermethrin (colorless insecticide, due to its viscosity, helps to increase the duration of the drug).
• Malathion (a poisonous substance that is used against any insects).
• Synergist piperonyl butoxide (helps to accelerate the penetration of a poisonous substance through the cuticles of arthropods).
• Solvent.
• Talc (most powder, filler).
• Lubricant.

The main properties of this drug

In the fight against bedbugs, you will need more drug than in the fight against other insects. The structure of their proboscis is provided for blood supply, it is difficult for them to swallow powder. Therefore, the composition of the dust is aimed at destroying the insect by tactile contact. The toxicity of this substance is not high and allows a person to stay indoors throughout the entire period of pest control.

Popular Dust Based Powders

On the shelves of non-grocery stores, we see a huge assortment of various drugs for bedbugs. Here is a list of the most effective dusting powders:

• Clopoveron. The drug is designed for use by specialists in large areas of infection, so it rarely appears on the market. It is an order of magnitude more expensive than other insect control products.
• Dust " Clean house". This is very reliable remedy used in living conditions... It has moderate toxicity, so the instructions for use should be strictly followed.
• Phenaxine is odorless and provides good results.
• Fas-take - serves as an analogue of Phenaxin.
• Riapan. The active ingredient in this powder is permethrin. The effect of the drug lasts for 3-4 days.
• Dust "Tornado". One package is enough for 70m2, the approximate cost of the drug is from 20 rubles.
• Neopin. A type of powder that can be diluted with water and treated hard-to-reach places.

How to use?

To poison bedbugs yourself is quite simple. During the processing of an apartment, you must follow the rules:

• Preparation for work. We remove food products, personal hygiene products, dishes, animals and other residents from the premises, open all windows.
• Overalls. Wear as close-fitting clothing, gloves and glasses as possible. Be sure to use a respirator to avoid inhaling the pollen powder.
• Use a washcloth or wide brush to apply the powder.
• We distribute it thin layer on the inner surface of the bed, carpets, on the baseboard in the habitat of pests.
• In places where there are cracks, we try to carefully pour the powder.
• If you need a liquid consistency of dust, and you do not know how to dilute it, pay attention to the instructions written on the package.
• If pollen gets in your eyes, rinse thoroughly with running water.
• After finishing the processing of the room, we take off the clothes and send them to the wash. We take a shower and go for a walk for 3-4 hours.
• After the specified time has elapsed, we proceed to cleaning the premises. Using a vacuum cleaner, remove the remains of powder from upholstered furniture, rinse the rest of the surfaces with a soda solution.

Harm to humans

The question often arises as to how toxic the antibite remedies are. Scientists say DDT has a detrimental effect on the environment and interferes with the human endocrine system. However, the healthcare organization considers this drug to be moderately toxic. The risk of chronic poisoning is present if it is used daily for a long time. With long-term use of out dust at home, there is a risk of disruption of such body functions:

• The endocrine reproductive system is destroyed.
• Sperm quality decreases.
• There is a risk of premature birth.
• The menstrual cycle gets confused.
• The quality of lactation is deteriorating.

Advantages and disadvantages of this drug

It is very effective against insects. However, compared to other insecticides, the powder is not very convenient to use. More about the benefits of dusting products:

• Most powders do not need to be diluted in water. However, there is a dust that is used in liquid form How to dilute it is written in the instructions on the package.
• Low price.
• One packet is sufficient for a large lesion area.
• The dust acts on more than 20 species of insects. However, bedbugs are one of the few who get used to the toxic properties of dust.
• It is less toxic to humans.

What are the disadvantages of the powder:

• Inconvenience to use. The powder must be scattered and then rubbed onto the surface.
• Weak concentration of toxic substances.
• Characteristic smell.
• Bed bugs develop immunity to certain powders.

What is dust

To get rid of bedbugs, our readers advise the Pest-Reject repeller. The operation of the device is based on the technology of electro-magnetic impulses and ultrasonic waves! Absolutely safe, ecological product for humans and pets.

It turned out that DDT is a terrible poison not only for insects and rodents, but also for humans. It is able to accumulate in the body, causing changes at the genetic level. The tool increases the risk of developing oncological diseases, allergies. Recent studies have shown that it negatively affects the nervous system. It is practically not excreted from the body, which makes it so dangerous.

Modern preparations based on dust

If the product is of Chinese origin and has a strong, relatively instant effect, then it almost certainly contains this prohibited substance. Everyone's business is to decide whether to use it in their home or not.

What to look for when choosing a dust

When buying an insecticide, you need to pay attention to its characteristics:

• action
• best before date
• presence or absence of smell
• mode of application

It is best to purchase an odorless powder. It is important that the expiration date has not expired. It is best to target insecticides from renowned manufacturers and with funds produced in Russia.

Many Chinese powders can contain high doses of DDT and be completely uncertified. Very often, the composition of oriental products remains unknown to consumers, which creates a potential health hazard.

How to get rid of bedbugs (video)

Dust for the fight against bedbugs

Dust from bedbugs is highly effective. It is applied in places where insects accumulate in a thin layer. In order to exclude harmful effect on humans and animals, everyone must be removed from the room during processing, and food products must be taken to a safe place. Processing is carried out in a respirator and rubber gloves, and after it they thoroughly wash everything with soap open areas skin.

After 6 hours in the room, it is necessary to collect the remains of the powder with a vacuum cleaner and wash all surfaces very well with water, soap and soda.

Flea control

Dust allows you to get rid of basement and other types in 1-2 applications. Fleas do not feed on anything other than blood, therefore dust powder acts on them, getting through the skin.

Processing the lower tier of an apartment at a height of up to 1.5 meters allows you to kill all adults. Re-processing is required after a week or two in order to destroy those fleas that hatched from the eggs remaining after processing.

Dust powder package is enough for disinfection of 10 square meters of surfaces. The standard package contains 50g of the product.

The room should be disinfected in the same way as described above. It is important after cleaning to ventilate the room, leaving open windows for 20 hours.

Will dust help lice

• To remove lice, you need to lather your head with dusty soap, putting on a plastic cap after the procedure.
• Wrap a towel over your head and leave to act with the solution for 1 hour.
• After that, you need to thoroughly rinse your hair and comb it out.

The unpleasant qualities of soap include:

• sharp disgusting smell
• high toxicity to humans

Today, it is extremely difficult to purchase dusty soap - its production has long been discontinued due to the ban on dust and DDT. It is easier and safer to use folk remedies to combat lice, as well as pharmaceutical preparations.

Many people confuse dust and. Therefore, the latter is beginning to be used as a remedy for lice, especially after the stories of those who lived in Soviet times. Tar soap absolutely harmless to humans and even able to improve the condition of the skin. But, unfortunately, it is completely ineffective for the treatment of head lice - it is impossible to get rid of lice with it.

Otmar Zeidler is a chemist, through whose efforts this substance was synthesized in 1873. However, long time it did not find application, and only in 1939, thanks to the efforts of P. Müller, a Swiss chemist, the insecticidal properties inherent in dichlorodiphenyltrichloroethane were revealed. Already in early 1942, DDT went on sale, quickly gaining popularity around the world.

With its help, it was possible to effectively resist typhoid and malaria, diseases that at that time had the greatest degree of danger to mankind. Spraying was enough to ensure reliable protection territory over the next few months.

Mueller's efforts were appreciated, and already in 1948 he received the Nobel Prize in Medicine. However, the substance DDT also had a number of negative characteristics, which led to significant environmental pollution in many countries. As a result, already at the beginning of the 70s of the last century, serious restrictions on its release and use came into effect, which are still relevant to this day.

Among the main merits attributed to dichlorodiphenyltrichloroethane, one cannot fail to note the following:

• It was thanks to DDT that the typhus outbreak was localized in Naples in 1944. This was the first ever case of a winter epidemic stopping;
• the use of DDT avoided deaths from malaria that hit India in 1965;
• in the same India for 50-60 years. Doom-Doom fever raged, but thanks to the use of the drug, many problems were avoided.

Fighting epidemics with DDT spraying

Basic properties of DDT and its analogues

DDT - chemical preparation, included in the category of substances based on compounds of the organochlorine type. It has a crystalline structure, its color can be different - gray, white or slightly brownish. Does not interact with water, although under the influence of most organic solvents, including ketones, aromatic hydrocarbons and others, demonstrates excellent solubility.

V natural environment dichlorodiphenyltrichloroethane has a long period decomposition with negative impact on water resources, plants and directly the soil itself.

Its transmission takes place along the food chain, the toxic chemical tends to mutate, and when it penetrates into a living creature, it affects the tissues and the nervous system, negatively affecting the ability to reproduce.

Over time, the pesticide accumulates in the body - removing it to the outside through purification systems impossible.

As for how DDT is deciphered, there is a combination of three components at once - dichloro-diphenyl-trichloroethane, while the content of 4,4'-isomers reaches 75%.

Among the main analogues of this insecticide, the following are especially distinguished:

• Aldrin is a substance with rather high toxic indicators, prone to accumulation in the body and not amenable to decomposition. Has an increased danger to humans, which led to its prohibition in a number of countries.
• Dieldrin is a chemical based on aldrin, but in a lower concentration. For living beings it is less dangerous, therefore it is very effectively used in agriculture.

Usage aspects and precautions

When using the drug, you should adhere to certain rules without forgetting about your own safety. It is important to remember that dichlorodiphenyltrichloroethane is extremely dangerous and toxic.

Relevance of pesticide use

The pesticide DDT is especially productive in the following situations:

The manufacturer recommends storing dichlorodiphenyltrichloroethane in a dry and dark place at room temperature. It is important to exclude contact of DDT with food, children are also strictly prohibited from accessing the chemical. Before use, you should make sure that the expiration date is up to date.

Rules for the treatment of open areas with the drug

When treating open areas, the following factors should be considered:

• work is carried out in protective clothing;
• a mask for the eyes and a headdress are required;
• at the end of processing, shake off DDT from clothes, take a shower and change into a clean set;
• optimal temperature regime: + 20-22 ° С, the weather should be calm;
• during processing, there should be no pets nearby.

Work with reliable protection

Home use

Processing is carried out in the following order:

1. All unnecessary things are removed from the premises - furniture, food, and so on. It is important to take care of personal protection - work is carried out with gloves and a respirator.
2. Surface treatment is best done with a brush. First, apply a pesticide to reverse sides carpets, thresholds and cladding panels, after which they move on to pieces of furniture and ventilation. It is important not to forget about upholstered furniture and all kinds of joints and gaps.
3. After processing, they wait about 3-4 hours - during this period it is not recommended to stay indoors. After applying dichlorodiphenyltrichloroethane, wash your hands thoroughly and change into clean clothes.
4. Upon return, the room is ventilated. Smooth surfaces are cleaned with a soda-soap solution. Work is also performed with gloves. Upholstered furniture is cleaned with a vacuum cleaner. From hard-to-reach places dichlorodiphenyltrichloroethane need not be removed - so it will continue its protective effect in the future.

The main benefits of dust

DDT for home use from pests

DDT has the following advantages:

• a wide range of actions - from domestic insects to agricultural pests;
• high degree of processing productivity;
• ease of use - the dust does not require mixing or dissolution, but is immediately ready for use;
• small volumes for the treatment of territories - 50 g is enough for application per 10 m2;
• acceptable price policy- dichlorodiphenyltrichloroethane has an affordable cost, which has a positive effect on its demand and popularity.

Effective pest control

First aid for drug poisoning

For man lethal dose dichlorodiphenyltrichloroethane is 5-10 g, although with a defeat of 1-1.5 g, very serious consequences are possible. There is a particular danger oil solutions from which the pesticide is absorbed at the fastest rate.

When poisoning with dust, there is a feeling of nausea, general weakness of the body, heart problems, pain in the limbs, fever, and a number of other symptoms appear. Possible liver and kidney problems. In such a case, delay is unacceptable, you should seek qualified medical help as soon as possible.

Before the arrival of the medical team, a copious gastric lavage should be performed. To do this, use a suspension activated carbon or a solution based on sodium bicarbonate in 2% concentration. After that, you should take a saline laxative. It is highly contraindicated to use castor oil.

Effects of various pesticides on humans

The answer to the question, what is this dust and how the drug affects people, has been received. Its use, despite all its effectiveness, is fraught with many dangers, therefore, in the absence of proper knowledge and experience, it is worth abandoning dubious experiments and entrusting the work to professionals. This will make it possible to save not only time and money, but also health.
