Deltamethrin is the active ingredient of insecticides (pyrethroids) that are used in agriculture, personal plots, as well as in household, sanitary, and medical practice for disinfestation against harmful and synanthropic insects.

Physical and chemical properties

Technical deltamethrin is a white, odorless crystalline powder. The substance is practically insoluble in water, but emulsifies well in it. Deltamethrin is highly soluble in organic solvents (acetone, ethyl alcohol, dioxane), mineral and vegetable oils, moderately soluble in benzene, xylon and other aromatic solvents, slightly soluble in kerosene. The substance has a slightly acidic reaction and is stable to light. Deltamethrin is highly insecticidal because is the most active isomer in pure form out of 8 possible.

Physical characteristics:

• molecular weight: 505.2;
• insoluble in water;
• melting point: 98-101 °C;
• volatile;
• flash point: 42 °C (technical product can withstand heating at 40 °C for 6 months).

Effect on insects

Most pyrethroids contain chrysanthemum acid as a base. In turn, the radicals in the general formula of deltamethrin are represented by bromine atoms. The active substance contains only 1 isomer, which determines insecticidal properties, the rest are removed. Due to this, preparations based on deltamethrin have high insecticidal activity. Like other pyrethroids, deltamethrin interferes with the function of nervous system insect, affecting calcium metabolism in synapses and sodium-potassium channels, resulting in excessive release of acetylcholine during the passage of a nerve impulse. The drug causes severe stimulation and damage to the motor centers. The protective effect lasts 15 days.

Application

Agriculture. Preparations based on deltamethrin have strong lipophilicity, so even rain cannot affect the quality of processing. The active substance is effective against gnawing, sucking and coleopteran insects. Preparations containing deltamethrin are approved for use against pests:

• potatoes (Colorado beetle), wheat (chickweed, pest bug, thrips, aphids, grain flies, grain beetles, fall armyworm);
• barley (cereal flies, flea beetles, pyavitsa);
• corn (corn borer, bollworm);
• rapeseed (bugs, rapeseed beetle, flea beetles, white beetles);
• sugar beet (meadow moth), etc.

Personal plot of land. Preparations based on deltamethrin are recommended for controlling pests of vegetable and fruit crops:

• cabbage (cabbage cutworm, turnip and cabbage moths, leaf-eating caterpillars, flea beetles);
• potatoes (Colorado beetle);
• apple trees (aphids, leaf rollers, codling moths);
• tomato open ground(gnawing cutworms, Colorado potato beetle).

Medical, sanitary and household disinsection. Preparations based on the active substance are effective in killing flying (mosquitoes, flies) and crawling (cockroaches) insects.

Toxicological characteristics

Deltamethrin is highly toxic to insects, bees, warm-blooded animals and humans, and is highly toxic to fish. The active substance exhibits little stability in environment. Residual amounts of deltamethrin at correct use are not found in plants and do not accumulate in soil. Preparations based on the active substance belong to the third class of danger for humans and the first for bees.

C 22 H 19 Br 2 NO 3 – formula of the substance deltamethrin, synonymous names for which are “Supermethrin”, “Deltacid”, “Decamethrin”, “Butoflin”, “Splender”, “K-Otrin”, “Butox”, “K” –Obiol”, “Decis”, “K-Otek”, “Vesta”, “Fas”, “NRDC-l61”.

Deltamethrin belongs to the group of acaricide-insecticides. This is one of the pyrethroid substances in the preparative form, which is sold in a 2.5% emulsion concentrate (in the Biorin preparation - 1%). Deltamethrin has contact and intestinal methods of penetration and influence on pest organisms.

This substance is widely used in the agricultural sector, as well as in private households. It is used both in everyday life and in sanitary and medical practice, that is, wherever the fight against harmful insects, including synanthropic insects, is relevant.

In the agricultural complex it is used against bedbugs, leech, aphids, thrips, bread beetles, grain flies, grain and cotton bollworms, corn borers, flea beetles, Colorado potato beetles, meadow moths, rapeseed flower beetles, white flies, etc.

In private farms it is used against cabbage and turnip moths, flea beetles, cabbage cutworms, leaf-eating caterpillars, Colorado potato beetles, cutworms, aphids, codling moths, and leaf rollers. In sanitation - against cockroaches, flies, mosquitoes. Biorin is easy to apply and very effective - it gives a lasting result just a quarter of an hour after application.

Chemical and physical characteristics of deltamethrin

IN technical form this substance is a crystalline, odorless white powder. It emulsifies well in aqueous suspensions, but does not produce a true solution in water. But deltamethrin will dissolve well in organic solvents (ethyl alcohol, dioxane and acetone); it is moderately soluble in benzene, xylene, and other aromatic solvents. The substance is quite weakly soluble in kerosene, it is characterized by stability to light and a slightly acidic reaction.

Deltamethrin is the most active of the eight possible isomers in its pure form, which is why this substance has such a high level of insecticidal activity. Other isomers are removed from the technical substance. Since it is practically insoluble in water, its use after mixing in water is non-toxic - deltamethrin is toxic only in mineral and oily plant solutions. It is characterized by volatility, its melting point level is from 98 to 101 ° C, although the flash point is at 42 degrees, however, in the form of a technical product, the substance can withstand heating well up to 40 ° C for six months.

Effect of deltamethrin on harmful organisms

This substance disrupts the functionality of the nervous system; signs of poisoning are severe agitation with subsequent damage to the functioning of the motor centers. The protective effect of deltamethrin lasts up to 15 days. In addition, it is characterized by phytotoxicity, which must be taken into account when processing certain types of plants. For example, deltamethrin at 0.01 percent concentration will burn young Brussels sprouts plants. It also affects the development of growing beans.

It must be taken into account that it is also harmful to fish, and is quite highly toxic to humans, beneficial insects, and warm-blooded animals.

A child has a much higher risk of getting lice than an adult. Therefore, treatment and prevention of pediculosis in children has to be carried out more often. It is important that the treatment is convenient to use, does not cause allergies or discomfort, has a mild active base and is suitable for use in childhood.

To combat head lice in children, you can use any popular shampoos: (Veda-2), Hygia, Degtyarny, Pedilin, etc.

This remedy may be suitable for those who have not been helped by regular shampoos made for people.

The shampoo has received many positive reviews from those who have used it to treat lice. But there are also skeptical opinions about the possibility of using it on people, especially children, because in fact, Lugovoi is certified as a drug for animals. The manufacturer does not provide explanations or instructions for use on humans; responsibility for the consequences of use lies entirely with the person who used this product on their child.

Composition and principle of action of Meadow shampoo

The shampoo is available in bottles of 180 and 270 ml, the line is represented by several types: there are options separately for cats, separately for dogs, as well as a common option for both animals. Any product is suitable for treating a child’s hair, but the detergent and insecticidal base is softer in cat shampoo.

Includes:

• deltamethrin is a synthetic insecticide, an analogue of natural insecticides contained in the flowers of plants of the Asteraceae family;
• plant extracts: chamomile, calendula, coltsfoot, plantain, burdock and dandelion roots, thyme, St. John's wort, sage. The composition of herbal additives in shampoos for cats and dogs is different.
• nipagin – antiseptic;
• glycerin – organic compound in the form of alcohol;
• lanolin – natural wax, extracted from sheep's wool;
• Excipients.

Deltamethrin is a modern active insecticide with a wide spectrum of action, essentially an ester, it quickly destroys the insect through contact action: it almost instantly paralyzes it, and after a while causes death.

Severe itching In case of pediculosis, it is not the insects themselves that cause it, but the saliva they secrete when they bite.

Deltamethrin is more effective than many well-known insecticides, while acting more mildly. However, it is also toxic to humans (hazard class 2), although it is much less dangerous than many insecticides. The concentration of deltamethrin in the shampoo is small, and yet before use you need to carefully read the information on the bottle, or even better, ask your doctor for advice.

Extracts of calendula, chamomile and antiseptic nipagin effectively destroy potentially dangerous bacterial microflora on the scalp, preventing the development of flea dermatitis, suppuration in bite sites, relieve itching from bites, and soothe the skin. Glycerin, lanolin and herbal extracts protect and soften hair shafts, stimulate metabolic processes in the skin and hair follicles.

Application

Pros of using shampoo:

• effective against pediculosis, quickly destroys insects;
• does not need to be left on the hair for a long time;
• acts gently and does not cause a burning sensation on the skin;
• easy to use;
• relieves itching and heals wounds from bites;
• destroys dangerous bacteria and microbes;
• takes care of hair;
• has a pleasant smell;
• foams well;
• is used sparingly;
• It's inexpensive.

What sets Lugovoi shampoo apart from many other products is the fact that you do not need to hold it on the child’s head for a long time(for comparison, some lice treatments need to be left on the hair for 20-40 minutes). In relation to a restless child, this is most relevant - the sooner the procedure will take place, all the better.

The shampoo forms a thick foam and is much gentler than many other insecticidal preparations, which is important when treating delicate children's skin. It may cause mild irritation if it gets into your eyes and mouth, but it does not sting your scalp. Therefore, you just need to make sure that the child’s mouth and eyes are closed during the procedure.

Herbal extracts care for skin and hair, soften the sensations caused by the action of the insecticide, and leave a pleasant aroma on the hair. One bottle of shampoo is enough for many uses, and the cost of this product is several times lower than anti-pediculosis products offered in pharmacies for people (certification of veterinary drugs is much cheaper than human ones).

The drug Delta Zone is a modern microencapsulated insecticide, which is quite effective against bedbugs, cockroaches and some other synanthropic insects. A special feature of the drug is its almost complete absence of odor, which is important when used indoors.

Delta Zone is produced by the Korean company Kukbo Science Co., LTD. The product is adapted for household use, and is sold in 50 ml bottles, which contain a specially prepared insecticide in a highly concentrated form. Before use, the drug must be diluted with water in the proportions required by the instructions: one bottle, which can be purchased for about 650 rubles, is enough to treat about 100 m² of area.

Due to its fairly high efficiency, Delta Zone allows you to reliably get rid of bedbugs and cockroaches by the residents of the premises themselves. To use the product you do not need to be a professional exterminator or have special equipment– an ordinary household spray bottle is sufficient.

Judging by the reviews of those people who have already observed the drug in action, the fight against bedbugs and cockroaches often ends after the first treatment. At the same time, a pronounced protective effect of the product is observed long after its use.

The active substance of the drug Delta Zone and the mechanism of its action on insects

The active ingredient in Delta Zone is the very powerful insecticide deltamethrin. This substance has a contact and intestinal poisoning effect, as a result of which it can effectively destroy both (bugs, fleas) and those that do not feed on blood (cockroaches, ants, carpet beetles, etc.)

The contact mechanism of action of deltamethrin is based on its ability to quickly penetrate the chitinous integument of the insect. Therefore, to successfully poison, for example, a cockroach or a bedbug, it is not at all necessary to force the insect to eat the drug - it is enough that the drug gets on its paws or on the surface of the body. After this, the insecticide penetrates the internal tissues of the insect and leads to its poisoning.

The contact poisoning effect of the Delta Zone drug is especially important in the fight against bedbugs, which eat nothing but human blood, and it is simply impossible to force them to eat poisoned bait.

Having penetrated the internal tissues of the victim, deltamethrin disrupts the functioning of the nervous system, resulting in rapid paralysis and subsequent death of the insect. At the same time, the substance is not dangerous for warm-blooded organisms (including humans), since it is quickly destroyed by the corresponding enzymes.

Thus, for effective destruction For bedbugs and cockroaches, it is necessary to ensure that the insecticide reaches the surface of the insect's body. It was to solve this problem when developing the Delta Zone drug that the principle of microencapsulation of the active substance was used - deltamethrin is in a colloidal solution in the form of microscopic capsules, which, after surface treatment and evaporation of water, remain here in the form of a thin layer.

The active substance on the treated materials cannot be seen with the naked eye, but insects, running over such a surface, “get dirty” in microcapsules that stick to the legs and body of the future victim.

The photos below clearly demonstrate this effect of microcapsules sticking to insects:

On a note

In the instructions for use and in some catalogs, the name of the drug is indicated as “Delta Zone m.k.” The last abbreviation just means microencapsulant.

In the case of cockroaches and ants, the Delta Zone has a double effect (in addition to the contact poisoning effect, it also has an intestinal effect): these insects constantly clean their legs and antennae with their jaws, and the drug additionally enters their digestive tract. Bedbugs do not do this, however, as practice shows, their flat, wide body collects much more insecticide than the legs of cockroaches, and therefore it also attacks quite quickly, which is confirmed by numerous reviews.

On a note

As mentioned above, one 50 ml bottle of Delta Zone after dilution is enough to treat approximately 100 square meters. However, it is important to understand here that a surface of 100 m² does not mean the area of ​​the apartment, but the total area of ​​all treated surfaces, which includes the walls of bedside tables, the surfaces of sofas, interior spaces cabinets, etc. In general, to the usual two-room apartment Usually you should buy two bottles of Delta Zone at once. It is useful to take into account individual characteristics case: if cockroaches are present only in the kitchen or, for example, bedbugs are only present in the bedroom, then sometimes a smaller amount of the drug will be enough.

Advantages and disadvantages of the drug

“Tell me where to buy Delta Zone in Tver? My sister from Yaroslavl called me and said that they removed all the bedbugs from my mother’s old apartment in one go, and in addition, the moths disappeared immediately. I've been to all the stores and haven't even heard of such a product anywhere. But I’m somehow afraid to order online...”

Yana, Tver

Delta Zone also differs from most traditional ones in the absence of odor.- even immediately after treating the apartment, no toxic aromas are felt at all. At the same time, there are many cases where apartment residents had to simply throw away furniture that could retain an unpleasant “medical” odor for months after the apartment was treated by some pest control services or SES.

Other advantages of the drug:

1. Prolonged action - in those places where the product is not washed off during wet cleaning, it remains effective for several months. This means that even if, for example, a month after treatment, larvae hatch from the surviving bedbug eggs, then with a high probability they will not survive even a few days.
2. Barrier effect – the drug provides reliable protection from the penetration of insects from neighbors (more precisely, insects penetrate, but crossing the corresponding “barrier” in the form of a surface treated with the drug, for example, ventilation, quickly die soon after that).
3. No stains or drips on the furniture in the places where the product was applied.
4. Safety for humans and pets. Of course, Delta Zone is not water, but a poison for insects, however, if the instructions for use are followed, the drug does not lead to any unpleasant sensations or signs of poisoning in humans and animals.

As for the disadvantages of the product, perhaps the main disadvantage of the Delta Zone drug from the consumer’s point of view is its price. A bottle that is enough for processing studio apartment, can be bought for about 650 rubles. This encourages many to use, albeit significantly less effective, but not so expensive means - for example, boric acid or old odorous Karbofos.

In addition, deltamethrin is ineffective against bedbug eggs (as are all insecticides belonging to the pyrethroid class). Although in practice this is not so important: larvae hatching from surviving eggs quickly die, since microcapsules of the drug remain active on treated surfaces for a very long time.

On a note

Another disadvantage of the Delta Zone can be considered some difficulty in purchasing the drug. You can only buy it via the Internet: in Moscow or St. Petersburg, the buyer will receive the order within 1-2 days, but in other regions of Russia the drug can take more than a week to be delivered. People who need to remove bedbugs as soon as possible are not always willing to wait that long.

“We tried to buy it in Rostov - it was useless, there is no Delta Zone here, they only send it by mail from a store on the Internet. Well, God bless him, there’s no fire here. We ordered it and it arrived. They dissolved it strictly according to the instructions and processed it so that not a single millimeter of dry material remained. And there was no smell, but they actually collected a bunch of dead cockroaches. It was beautiful for three months! And what? Then the neighbors began poisoning them with something smelly, so the cockroaches crawled from them to us out of despair. They are dying slowly, but it looks like the war is not over yet.”

Valentin, Rostov-on-Don

Despite certain shortcomings, the totality of consumer characteristics of the drug Delta Zone makes it currently one of the most preferable options in cases where bedbugs or cockroaches need to be removed as quickly and reliably as possible, without unpleasant odor indoors and without the risk of poisoning yourself.

Instructions for use Delta Zone

Depending on what insects are supposed to be destroyed, Delta Zone concentrate is diluted in different ways:

1. Cockroaches, flies - 50 ml of product per 3.5 liters of water;
2. Bedbugs, fleas, ants - 50 ml per 5 liters of water;
3. Mosquitoes, moths - 50 ml per 10 liters of water.

The resulting solution can be poured into a regular household spray bottle (spray).

Then, in case of destruction of bedbugs and cockroaches, the following actions are performed:

1. Access is provided to all possible hiding places for insects - baseboards, walls behind carpets (it is advisable to remove the carpets themselves from the walls), back walls bedside tables and sofas, the inner surfaces of sofas, mattresses (in case of destruction of bedbugs), shelves in pantries and closets.
2. It is advisable to hide dishes, linen and children's toys in plastic bags.
3. All people (except the handler) and pets leave the premises. If the apartment has an aquarium, then it is covered with glass.
4. Next, all surfaces on which insects could potentially move are sprayed with a spray bottle. The approximate consumption of the finished working solution is 50 ml per square meter non-absorbent surface, or 100 ml - for highly absorbent surfaces. Particular attention must be paid to door and window frames, ventilation ducts and baseboards, when removing cockroaches - the back surface of the refrigerator and kitchen stove, and when removing bedbugs - mattresses and sofas.
5. After spraying, the apartment is left for 2-3 hours so that the product dries and adheres to the surfaces.
6. After 2-3 hours, you can wet clean the apartment (it is not recommended to wipe hard-to-reach places that people and pets do not touch - to maintain a long-term protective effect after treatment).

“Thank you to the creators of the Delta Zone. Before this remedy, many other chemicals were used, from dichlorvos to kerosene, but the bedbugs immediately appeared again. Half our house is infected with them. After using the Delta Zone, there has been no sign of insects for three months, although after that we already managed to rearrange it and washed the entire apartment many times. At the same time, our neighbors have bedbugs and cockroaches, but ours is clean. We used two jars of funds for a two-room apartment.”

Lyudmila Ivanovna, Kaliningrad

It should be taken into account that bedbugs or cockroaches can enter the premises from neighbors. Therefore, even if the entire population of insects in your apartment is completely destroyed, but at the same time, for example, your neighbors have a real bedbug infestation, then, of course, the bloodsuckers will visit you regularly. Thanks to the barrier effect of the Delta Zone drug, most of the bedbugs will die immediately after migration, however, to reliably solve the problem in such a situation, it is advisable to cooperate with neighbors and fight insects together.

Safety rules when using the product

Despite the fact that the Delta Zone drug is odorless and its active substance is enclosed in microcapsules, nevertheless, working with the product, as with insecticides in general, requires compliance with standard safety rules:

1. The treatment should be carried out in clothes with long sleeves, respirator, rubber gloves and safety glasses.
2. During treatment, food should not be eaten in the same room.
3. If the working solution or concentrate gets on your skin or eyes, rinse them with plenty of clean running water.
4. If the room is very large, then during processing every 40-50 minutes you need to take a break for at least 10 minutes, during which the handler leaves the apartment for fresh air.

Owners of cats and female cats should be especially careful - these animals are very sensitive to pyrethroids in general and to deltamethrin in particular.

You can purchase an original drug without the risk of running into a counterfeit, for example,
