Cucaracha insecticide: instructions for use, precautions, first aid for poisoning

insecticide cucaracha instruction
Cucaracha insecticidal instruction

Good day. Last month I was engaged in independent breeding of bugs.

Fortunately, not at home. A neighbor asked through several houses to help, otherwise a whole colony of these parasites had already settled in his old couch.

My main weapon, I chose a tool, which I saw a lot of positive reviews. Carefully and slowly, the task of exterminating the bugs was completed. Now I want to tell you about the instructions for the insecticidal agent Cucaracha. With proper use, the drug is able to quickly solve the problem.

Cucaracha liquid concentrated remedy for cockroaches, bugs and other harmful insects 50 ml

Cucaracha insecticidal agent (concentrate) is used to kill insects indoors

Destruction of bugs

Cucaracha is diluted with clean water at a temperature of about + 19 + 23 ° C, with constant stirring. Proportions for mixing - 2.5 g of the drug per 1 liter of water.

Important!
Further, when the working composition is ready for use, it must be applied to the surface, next to which bugs were found. Also, all hard-to-reach places where bedbugs could create their colonies and actively reproduce are necessarily processed.

It can be gaps in the floor, between the panels of walls and floors, in the corners of the pantries, in furniture and under the baseboard, and so on. The processing rate is about 50 ml per square meter of surface. If you process wood or plywood, for example, the back of cabinet furniture, then the expense can almost double.

Kukaracha KE use over a large area. With this substance, only habitats are treated at the beginning; and in cases of a large number of individuals and in inaccessible locations of bugs, for example, in wall cladding with dry plaster, then processing is carried out in an enhanced mode.

You must carefully spray all the places of the possible population, which include: gaps along the baseboards, borders, lagging behind the wallpaper, around the door window frames and ventilation grills, gaps in the walls, furniture, and also carpets on the back.

Extermination of cockroaches

Cucaracha is diluted with clean water at a temperature of about + 19 + 23 ° C, with constant stirring. Proportions for mixing - 5 g of the drug per 1 liter of water. Destruction of cockroaches begins, as a rule, with the kitchen. This is where their favorite place is. Here insects can always find food for themselves.

Even the smallest crumbs of bread on a table or floor are enough to maintain their vitality, and not to mention the garbage that accumulates in buckets, the packages with which are always left open. In addition, cockroaches are omnivores, their stomach digests paper, skin and even soap.

After processing the kitchen, it is necessary to process the places where cockroaches are likely to be found, first of all, the risers of the bathrooms, air ducts, the space under the bathroom, the gaps behind the skirting boards, not forgetting about the processing of the back surfaces of kitchen appliances.

Consumption rates

Cockroaches, larvae of flies use a working emulsion prepared by adding 5 g of the drug to 1 liter of water. (1 bottle of 50 ml = 10 l of working fluid from cockroaches per 100-200 sq. M).

Advice!
From bedbugs, fleas, adult flies, adult mosquitoes, rat ticks - 2.5 g per 1 liter of water (1 bottle of 50 ml = 20 l of working fluid from bugs 200-400 sq.m).

The consumption rate of the drug is from 50 to 100 ml per 1 sq. M from mosquito larvae 0.3 g per 1 liter of water. The consumption rate is 100 ml per 1 sq. m reservoir. The residual activity of the drug is 3-5 weeks. Active ingredient: cypermethrin 20%, malathion 10%.

When using the product, strictly follow the instructions.

The drug "Cucaracha" for the destruction of bugs

Bed bugs, as many years ago were a headache for many inhabitants, remained. No matter what people come up with, what means from bed bugs or use, it is quite difficult to remove them to this day.

One of the most effective drugs that are released to destroy domestic parasites is the remedy "Cucaracha" from bed bugs.

Reviews about it, in most cases, are only good, although the drug is rarely found on sale. But even this highly effective tool has both positive and negative sides.

Description

Remedies for domestic bugs are available in three forms: powder, gel, emulsion. "Kukaracha" from bugs is an acaricidal-insecticidal preparation in the form of a concentrated emulsion. The insecticide has a light yellow tint and a very unpleasant odor.

Intended for the treatment of bugs, mosquitoes, flies, cockroaches, fleas and rat ticks. It can be used for pickling:

  • residential premises;
  • non-residential premises;
  • in kindergartens, but not in play rooms and not in bedrooms;
  • in hospitals and sanatoriums, excluding wards for patients;
  • at catering enterprises, etc.

Solution preparation

This bug control agent is bred to the required concentration depending on the type of parasites that need to be destroyed. The drug "Cucaracha" from bedbugs, consumer reviews and instructions confirm this fact, it is necessary to breed at room temperature.

Attention!
To increase the effectiveness of the drug against these parasites, water needs to be heated. In warm water, the volatility of poisonous molecules increases, thereby increasing the effectiveness of "Cucaracha" (remedies for bed bugs).

For the solution, you need to take about 2.5 g of the emulsion and, continuously stirring, dissolve it in one liter of water. The prepared emulsion solution is applied to the surface with a spray gun.

Average expense per 1 sq. m - 50 ml. But when processing surfaces from wood or from other objects or things that are easily absorbing moisture, its consumption can increase to 100 ml / 1 sq. m

One small bottle (50 ml) of Kukarach's remedy for bedbugs, reviews of ordinary people only confirm this, it’s enough to process a room of 70 sq.m. Today you can buy this drug in large volumes - 1 liter, 5 liter.

The tool has a third hazard class - moderately hazardous substances.

The composition of the drug

Agents such as Cucaracha have a contact-intestinal neuroparalytic effect. But they do not destroy the eggs. Due to its long period of exposure to parasites - the insecticide remains active for 2 to 4 weeks - even those larvae that emerge from eggs also die.

Getting on the active substance of the product, the insect paralyzes, and after 3 seconds, it dies.

"Cucaracha", as a means to combat bugs, has in its composition:
- Malathion, at a concentration of 10%. This component belongs to compounds of the FOS group.

It is this substance of "Cucaracha" that is the poison of neuroparalytic effects. It completely destroys the work of the nervous system of parasites, first leading to the failure of all internal organs and muscles of insects, and then to death.

Malathion is very harmful to the body of arthropod domestic parasites. Getting into it, this component turns into a similar, but much more toxic substance - malaxion. Its toxicity is higher than that of malathion, so the parasites die very quickly.

Important!
The disadvantage of malathion, although it is included in many drugs for bugs, is the too high volatility of its molecules. Therefore, they cannot linger for a long time on the treated surfaces.

Sometimes parasites develop resistance to this component: insect organisms begin to produce special enzymes that break down malathion.

But, using the Kukaracha remedy for bedbugs, consumer reviews confirm this, such an effect can occur only with prolonged use of the drug. Combining with its other component (cypermethrin), malathion enhances and complements its action, and cypermethrin reduces its volatility.

Cypermethrin, at a concentration of 20%. It belongs to the group of pyrethroids and has a contact-intestinal effect on parasites. Adhering to the chitinous cover of arthropods or to its legs, cypermethrin blocks the nervous system of parasites, which leads to the death of pests.

The action of cypermethrin, which is part of Kukaracha, takes place over 20-30 days. This component is insensitive to high temperatures and ultraviolet.

Scientists, conducting studies of the action of this substance, showed that these parasites are not able to develop resistance to it.

Etching operations

The remedy "Cucaracha" from bedbugs, the reviews are always positive due to its instant effect on these parasites. You can verify this simply: spraying the pest with a solution. In less than five seconds, the parasite will die. The procedure for using "Cucarach" is as follows.

Preparation of the premises for insecticide treatment. Before proceeding with the processing of the infected room, it is necessary to prepare the room itself:

  1. To remove, then to wash, curtains, curtains, remove clothes, etc.
  2. Be sure to take out food, kitchen utensils, hygiene items or are tightly packed in plastic bags.
  3. Furniture must be disassembled: it will be possible to find pests nests, especially since the treatment with the agent will be carried out more carefully.
  4. Remove or remove animals, birds, people from the house.
  5. Clean well in the treated area. So, dust or “blockages” in the rooms will not be able to reduce the effectiveness of the drug.
  6. Buy personal protective equipment: gauze or respirator, tight rubber gloves, goggles, and prepare work clothes that can be washed or discarded.

Drug treatment. Room processing, regardless of what means from bed bugs will be used, always needs to start with the parasite nests found. Further, inaccessible places, cracks, a bedside zone are treated.

Advice!
Particular attention should be paid to upholstered furniture. Liquid remedies for bed bugs are well absorbed in fabric materials, so for such things they either make a large concentration of the solution, or pass through them several times.

The room is processed along the contour, not forgetting to splash the walls, ceiling and baseboards. If the floor is wooden, then the processing of cracks between the floorboards is required.

In the case when the room is very infected with parasites, "Kukaracha" will be more effective if you "raise" the floors (parquet, laminate), carpeting, wall panels, tear off or glue off the torn wallpaper.

It is necessary to spray only with a “closed circuit”: all doors, windows and ventilation are tightly closed. Be sure to de-energize the wiring.

Room cleaning after pickling. All products have toxicity to one degree or another, therefore, cleaning the room should be treated with special care.

You can return to the apartment only after a day. But before proceeding with the cleaning itself, the room needs to be ventilated by opening windows and doors for 3-4 hours.

First, the dead parasites are cleaned using an ordinary broom or vacuum cleaner. All fabric items left in the room are sent for washing, and the furniture is cleaned with a damp cloth.

Remember that cleaning the apartment after pickling is carried out only with gloves and overalls.

It is noticed that if you use the remedies for bedbugs (especially the Cucaracha preparation) correctly, that is, according to the instructions, then disinfection may no longer be necessary. But still, it will be much safer to repeat it after 10 days. So the processing efficiency will be 100%.

The effect of the drug on humans

Means of "Cucaracha" from bedbugs can significantly affect human health. But this happens only if the disinfector did not act according to the instructions and without protective equipment.

Attention!
For example, insecticide poisoning can cause intoxication or an allergic reaction. In this case, nausea, dizziness, disorder of motor functions and coordination of movements, lethargy and even convulsions appear.

And studies of this remedy for bed bugs by scientists have shown that malathion, accumulating in the body of warm-blooded creatures, can lead to cancer. But this is only with its large concentrations and with the constant presence of a person in rooms where there is malathion.

That is why, the residue left after processing must never be poured into the sewers or into water bodies. Indeed, for fish, this toxic chemical is toxic, causing an imbalance in the life support of water bodies.

Benefits of the drug

There are many such advantages. What is its speed, and after all, this is one of the main conditions for each inhabitant. It should be noted and its ease of application. A spray or a spray in such cases are the most convenient items for treating rooms with pesticides today.

The drug "Cucaracha" can be considered an economical substance. Using just one small bottle with an emulsion, you can completely process a private house or a medium-sized apartment. Large volumes of the drug are bought only when processing large areas, but this is usually done by professional pest control.

A low class of harmfulness (3), allows the tool to use it at home without compromising the health of all living in the room, people and animals.

The availability and price of Kukarach also plays an important role. The drug today can be purchased in any household chemistry store, a stall or in online stores, and at quite affordable prices.

The long residual action of the drug (10–30 days) allows even larvae that appear from the eggs after treatment of the apartment to be destroyed.

Drug shortcomings

Despite all the advantages of Cucaracha, this drug is a pesticide, so it still has drawbacks:

  • The toxicity of the drug, although not too high.
  • Harsh, and very unpleasant odor. But he, after airing, leaves very quickly.
  • Means of "Cucaracha" from bugs is an emulsion that needs to be diluted, and not a drug ready for use.
  • This remedy does not affect their eggs at all, although 100% kills larvae and adults. Reprocessing of premises, in connection with this fact, is recommended.
  • After treating the room with this drug, it must be left at least for a day, which is not always possible and convenient.

Despite the shortcomings of "Cucaracha" - this is exactly the substance that will be most useful in the fight against parasites. Many users claim its absolute, powerful, destructive power.

Important!
But again, it must be remembered that the effectiveness of Kukarach depends not only on its composition, but also on compliance with all points of its instructions.

Moreover, it is not only about the effectiveness of the product, but also about the health of consumers.

Buy means of Kukarach ke

Means of Russian production Kukaracha is very effective in use for independent processing of premises, territories, as well as summer or garden plots from insects.

The consumption of Kukarach means up to 50 ml of the agent per 5 liters of water, depending on the type of insect, is quite economical, which allows more than one treatment of the room. If the first time you can not get rid of insects, you will have enough funds for re-processing.

You can buy Kukarach’s product for the processing of residential premises (rooms, apartments, private houses, hostels, hostels and hotels) and children's rooms (except for bedrooms and playrooms), as well as non-residential premises: warehouses, industrial premises, as well as public catering facilities .

After treatment with Cucaracha, it is imperative to ventilate the room for at least 3 hours. The Cucaracha means of prolonged action, this means that it remains active for 3-5 weeks, this time is enough with a margin to destroy all the larvae.

The insecticidal agent Cucaracha is used both by professional disinfectants and is suitable for independent use.

Advice!
At the same time, it is necessary to strictly observe personal safety measures during processing using a respirator, eye protection, gloves and protective overalls.

With proper use and careful processing of the room, Cucaracha’s product will effectively save you from bed bugs, cockroaches, fleas, flies and mosquitoes.

On the use of insecticide and acaricidal means "Kukaracha KE"

The insecticide acaricidal agent "Kukaracha KE" is an emulsion concentrate in the form of a light yellow liquid. Contains two highly active compounds as active substances (DV): from the group of pyrethroids, cypermethrin - 20% and organophosphorus compound - malathion - 10%, as well as a surfactant, antioxidant, stabilizer and solvent.

The tool has an acute insecticaricidal effect against cockroaches, bugs, fleas, flies, mosquitoes and rat ticks and residual activity for 3-5 weeks.

According to the degree of exposure to the organism of warm-blooded when introduced into the stomach, the agent “Kukaracha ke” belongs to the III class of moderately hazardous, and when exposed to the skin - to the IV class of low-hazard drugs according to GOST 12.1.007-76.

Local irritant effect is moderate. Vapors are classified as moderately hazardous (class III). In vapors of a working aqueous emulsion (0.3% DV), a sensitizing effect has not been established; when exposed to the mucous membranes of the eyes, it causes a mild irritant effect.

With a single inhalation exposure to an aerosol of 0.3% aqueous emulsion, the agents in the zone of acute biocidal effect belong to the class II highly hazardous in accordance with the Classification of the degree of danger of disinfestation agents (Zbiocid.ac = 12).

Attention!
Vapors of 0.3% aqueous emulsion in the subacute biocidal effect zone belong to the class III moderately hazardous in accordance with the Classification of the degree of danger of disinsection agents (Zbioc. Subac = 10).

With a single contact with intact skin of a working aqueous emulsion, no local action was detected, but with repeated applications a mild irritant effect was established; a skin-resorptive effect was detected with repeated exposure to the skin of the hands.

MPC in the air of the working zone of the active substance - cypermethrin is 0.5 mg / m3 (hazard class II, vapors + aerosol); malathion - 0.5 mg / m3 (hazard class II).

The tool "Kukaracha KE" is intended for the destruction of cockroaches, bugs, fleas, flies, mosquitoes and rat ticks in objects of various categories: in residential and non-residential premises, in children’s (except for bedrooms and games) and medical and preventive (except for wards) for sick) institutions, as well as in public catering establishments by staff of organizations authorized to engage in disinfection activities.

Preparation of working emulsions and consumption rates

For the destruction of arthropods, freshly prepared aqueous emulsions are used in concentrations of 0.15-0.01% by active ingredient, which corresponds to 0.5% or 0.03% of the formulation.

For the preparation of working emulsions means "Kukaracha ke." diluted in water at room temperature, constantly and evenly mixing for 5 minutes. The calculation of the amount of funds necessary for the preparation of a working emulsion is shown in the table.

The consumption rate of the product is 50 ml / m2 (non-absorbing surface) and 100 ml / m2 (moisture absorbing). Remove the product from the treated surfaces (wet method - rags) 24 hours after application, but no later than 3 hours before the start of the working day.

From other places - in 3-5 weeks - after the loss of its effectiveness. Repeated processing is carried out according to entomological indications.

Use of funds

DESTRUCTION OF COCKTAILS. For the destruction of cockroaches, 0.15% (in terms of DW) of working water emulsions is used, selectively treating surfaces in places of detection, localization and on the paths of movement of insects.

Particular attention is paid to openings and slots in the walls, in door frames, thresholds, along baseboards, in claddings, as well as ventilation vents, at the junction of pipes of water, heating and sewer and sewer systems.

Processing is carried out simultaneously in all rooms inhabited by cockroaches.
At high and very high numbers, adjacent rooms are treated for prevention: to prevent migration and subsequent colonization of their cockroaches. Repeated treatments are carried out when insects appear.

DESTRUCTION OF BLADES. For the destruction of bedbugs, use 0.075% (DV) of the aqueous working emulsion means.

With a slight population of the premises, bed bugs process only their habitats; in case of high occupancy and in the case of wall facing with dry plaster, the places of their possible resettlement are also subject to processing: cracks along the skirting boards, borders, lagging behind wallpaper, around door, window frames and ventilation grills, cracks in the walls, furniture, as well as carpets from the back.

Important!
Simultaneous processing of all rooms is carried out only in dormitories, where frequent insect skidding is possible. Repeated processing is carried out when bugs are detected.

DESTRUCTION OF BLAS. To destroy fleas, they use 0.075% (DW) of a working water emulsion, treating the walls (to a height of 1 m), the surface of the floor at the places where the linoleum and baseboards lag behind, crevices behind the baseboards, carpets, walkways from the back.

When processing cluttered basements, these premises are preliminarily
opportunities are cleared of garbage, and then thoroughly irrigated. Repeated processing is carried out according to entomological indications.

DESTRUCTION OF FLIES. To destroy the imago of indoor or other species of flies, they use 0.075% (in terms of DV) of a working water emulsion, which irrigates the landing sites of flies in the premises, as well as the outer walls of buildings, garbage bins, garbage chambers and sand-collecting installations.

The emulsion flow rate is 50-100 ml / m2, depending on the number of flies and the type of surface to be treated.

To destroy the larvae of flies, 0.15% (DV) is treated with a working water emulsion of their breeding place (cesspools, waste, food waste) with an interval of 1 time every 20-30 days. Repeated treatments are carried out when winged flies appear indoors.

DESTRUCTION OF MOSQUITOES. To destroy mosquito imago, they use 0.075% (DW) of the working water emulsion, which irrigate the mosquito landing sites in the room, as well as the outer walls of buildings or inside fencing for garbage containers, where mosquitoes shelter in hot weather.

To destroy mosquito larvae, a 0.01% working water emulsion is used, which is uniformly sprayed on the surface of open natural reservoirs of non-economic importance and urban reservoirs: basements of apartment buildings, sewage, fire tanks, where mosquito larvae breed.

Advice!
Consumption rate of 100 ml per 1 sq.m. water surface. Repeated treatments are carried out according to entomological indications - the appearance of live mosquito larvae. Repeat treatment no more than 1 time per month.

KILLING RAT MITS. To destroy the rat tick, use 0.075% (DV) of the working water emulsion, which is irrigated - manholes, pipes of various communications, baseboards, walls and floors along them, as well as places of possible accumulation of mites - heated sections of walls and floors near heating appliances and thermal communications , the lower part of the furniture, working tables that are processed in their entirety, including those available in them
boxes.

In the presence of false coverings, behind which rodents can move, ceilings and walls are also subject to processing.

The consumption rate is 50-100 ml / m2 of the working aqueous emulsion, depending on the type of surface to be treated. Re-processing is carried out according to indications, but not earlier than 20-25 days after the first.

Precautionary measures

Physicochemical and analytical methods of quality control

In accordance with the requirements of normative documentation (TU), the product “Kukaracha KE” is characterized by the following quality indicators: appearance — liquid of a light yellow color and mass fraction of cypermethrin, component (20.0 ± 2.0%) and malathion, component (10.0 ± 1.0%). Quality control of the product is carried out according to these parameters.

Definition of appearance. The appearance of the product is determined by visual inspection of a representative sample.

Advice!
Determination of the mass fraction of cypermethrin (malathion). The mass fraction of cypermethrin (and malathion) is determined by GLC using a flame-ionization detector and a quantitative estimate of the DW by the absolute calibration method. ID identification is carried out by comparing the retention times in calibration and analyzed solutions.

Equipment, solutions, reagents:

  • a chromatograph with a flame ionization detector (PID) and a metal column 100 x 0.3 cm in size, filled with chromaton with 5% SE-30;
  • cypermethrin - a comparison sample from FMC, USA, containing 92.5% of the basic substance;
  • malathion - a comparison sample of the company "UFL" (India) - 98% of the main substance;
  • carbon tetrachloride brand "HH".

Preparation of calibration solution. To prepare a calibration solution of a sample of cypermethrin about 100 mg and malathion equal to 50 mg, weighed on an analytical balance with an accuracy of 0.0002 g,
dissolved in 20 cm3 of carbon tetrachloride, the solution is quantitatively transferred into a volumetric flask with a capacity of 50 cm3 and the volume is adjusted to the mark with a solvent.

The concentration of cypermethrin was 2.0 mg / cm3, malathion - 1.0 mg / cm3.

Sample Preparation. To prepare the analyzed solution, a sample of about 0.5 g, weighed on an analytical balance with an accuracy of 0.0002 g, is dissolved in 20 cm3 of carbon tetrachloride with stirring, the solution is quantitatively transferred to a volumetric flask with a capacity of 50 cm3 and the volume is adjusted to the mark with a solvent.

An aliquot of the resulting solution (2 cm3) is chromatographed at least 3 times.

Chromatographic conditions. Chromatography conditions for malathion:

  1. Column temperature - 190 ° C;
  2. evaporator temperature - 220оС;
  3. detector temperature - 210оС;
  4. the sensitivity of the scale of the electrometer - 5 x 10-10 a;
  5. retention time of malathion - 2 minutes 50 sec

Chromatography conditions of cypermethrin:

  • Column temperature - 250 ° C;
  • evaporator temperature - 280оС;
  • detector temperature - 260 ° C;
  • sensitivity of the electrometer scale –10 x 10-10 a;
  • cypermethrin retention time - 4 min. 05 sec

The determination of DW is carried out in parallel in the analyzed and standard solutions in 3 replicates. Calculation of chromatograms is carried out by height
chromatographic peaks.

Processing analysis results. The mass fraction of cypermethrin or malathion in percent (X) is calculated by the formula:

X = (Нх С.р. V) / (Нг.р.M)where

Hx and Ng.r. - the height of the chromatographic peaks of cypermethrin (malathion) in
analyzed and calibration solutions, mm;
Sg - concentration of cypermethrin (malathion) in the calibration solution, mg / cm3;
V is the volume of the analyzed solution, cm3;
M - weight of the sample, g.

Attention!
The result of the analysis is the arithmetic mean of 3 parallel determinations, the absolute discrepancy between the most differing values ​​of which does not exceed the permissible value of 1.0% for cypermethrin and 0.2% for malathion.

The limits of the permissible value of the relative total error of the measurement results are ± 2% for malathion and ± 5% for cypermethrin with a confidence level of 0.95.
