Lambda 25 MK remedy for bedbugs, cockroaches, fleas, ants, mosquitoes, flies, 1 l

Product description

Lambda 25 MK is presented in the form of a suspension, an opaque white liquid. It has an acute insectoacaricidal effect against the most common pests. Its main feature is its microencapsulated formula, which can only be achieved thanks to innovative technologies and highly qualified specialists.

The process of enclosing small particles of a substance in a thin shell of a film-forming material becomes the key to effective and reliable pest control. The thing is that the resulting microcapsules, after contact with the insect, stick to its body. On his paws he carries them to the nest, where he poisons his relatives. This significantly speeds up the destruction of the colony and allows you to reach the most cautious individuals. Residual activity persists for 6 – 8 weeks.

Preparing the room

Immediately before treatment, it is necessary to wet clean the apartment. The absence of dust will improve the adhesion of the insecticide to the surfaces being treated. It is also worth considering that after disinfestation you should refrain from cleaning for 2-3 weeks so as not to wash off the sprayed product. We move all the furniture in the bedroom away from the walls, at a distance necessary for the free passage of a person, this will simultaneously facilitate processing and increase its efficiency. We hide food in the refrigerator and wrap the dishes in cling film. We place clothes, bedding, toys in vacuum bags (this will prevent the spread of bedbugs to other rooms) and carry out heat treatment at high/low temperatures.

Advantages:

• economical consumption;
• high efficiency;
• simple method of application;
• Suitable for objects of various categories.

Principle of action: the active component has a contact, intestinal and repellent effect. Penetrating into the pest’s body, it disrupts calcium metabolism in synapses and the functioning of the nervous system. This causes excessive release of acetylcholine during the passage of a nerve impulse. Poisoning manifests itself in damage to motor centers and severe agitation.

Pros and cons of the product

South Korean bedbug poison has undoubted advantages. Most people who have tried this drug against house bugs note the following advantages:

• Quite high efficiency.
• Long lasting. Many insects die within 24 hours, but the poison continues to work for several more weeks. Often, owners manage to avoid repeated harassment and protect the apartment from new attacks.
• No unpleasant odor. The poison smells very faintly and does not cause any unpleasant sensations.
• Safety for people and pets. However, processing will have to be carried out in their absence. In addition, amphibians and reptiles, on which insecticides have a detrimental effect, are removed from the apartment.
• You can use the remedy for bed bugs more than once; bloodsuckers do not get used to it.

Like any poison against bloodsuckers, Lambda Probe has several disadvantages:

1. Linen, clothing and children's toys should not be treated with insecticide. They will have to be disinfected separately and thoroughly, because bedbugs love to hide in such places.
2. High price. Although 700 rubles is not exorbitant money, sometimes processing alone is not enough. Therefore, many residents consider it more appropriate to use the services of SES.

In addition, baiting takes a long time and causes a lot of trouble for the owners.

Mode of application

To prepare a working suspension, dilute the product with water at room temperature, stirring evenly. The calculation of the number of components you will need is indicated in the instructions, read it carefully.

Using spray equipment, apply to places where insects are detected, localized and moved: holes and cracks in walls, door thresholds, along baseboards, ventilation vents, joints between pipes of water supply, heating and sewer systems. Consumption rates: 100 ml/1 m2 for absorbent surfaces, 50 ml/1 m2 for non-absorbent ones. After a few hours, ventilate the room. Remove the solution from surfaces no earlier than after 6 – 8 weeks. Repeated treatments are recommended for entomological reasons.

Reviews

“Despite the high cost (695 rubles), we decided to opt for the Lambda Zone product; the bedbugs had bitten us and we couldn’t stand it any longer. The main criterion when choosing a poison was the absence of odor, since we have a small child. The first two days after the treatment, the bugs still bit at night, they already began to get upset that they wasted money and wasted time, but already on the third night, the bites became significantly less. A week later, there were no bedbugs or signs of their presence in the apartment...”

Natalia. Eagle

“Before we purchased Lambda Zone, we tried unsuccessfully to fight bedbugs using Mashenka’s pencil. Ease of use and no odor were the main reasons for the purchase. We cleaned the apartment. Two months passed, the bites disappeared, sleep returned to normal. Definitely, the product is worth its considerable money.”

Anna. Yeisk

Safety

It is prohibited for unauthorized persons and domestic animals to be in the treated area. It is mandatory to use personal protective equipment: overalls or gown, headscarf, rubber gloves, goggles, respirator. During disinfestation, it is not recommended to drink, smoke or eat. When finished, change clothes, rinse your mouth and wash your hands thoroughly with soap. Keep out of the reach of children and pets, away from medications and food products.

Mechanism of action on bedbugs

First of all, it is worth deciding on the terminology. In fact, the correct name for the chemical is Lambda Zone, and a lambda probe is called an oxygen sensor. But on various forums dedicated to the fight against bloodsuckers, the remedy for bedbugs Lambda Zonda is a fairly common name.

The drug is intended for the destruction of bedbugs and other annoying living creatures: ants, cockroaches. The mechanism of its action is quite simple: the poison, enclosed in a special capsule, enters the digestive organs of the bloodsucker and paralyzes its limbs. An insect, deprived of the opportunity to obtain food for itself, quickly dies.

One of the most pressing questions for apartment owners is whether Lambda Probe kills bedbug eggs or not. The poison is not capable of destroying oviposition immediately after treatment, but thanks to its prolonged action, the drug manages to cope with newborn bloodsuckers.

How to achieve maximum efficiency

The use of the drug in liquid form involves using a fine spray. Ideally, this should be professional high-pressure equipment. When processing it yourself, use a high-quality spray bottle - the smaller the holes in it, the better. This is a fundamental point, since it will allow you to achieve the same consumption of the composition as the manufacturer suggests. And the poison will get into even the smallest cracks and holes, which means the bug will be guaranteed to be defeated.

The drug must reach even the most difficult to reach places

Replacing the lambda probe

There is nothing difficult about the replacement. Before carrying out work, put the car on a lift, and also buy a new device. An approximate algorithm for replacing a part is discussed below.

• The sensor is mounted in front of the catalyst in the exhaust manifold of the car under the hood. If two devices are installed in the system, then the first is mounted in front of the catalyst, and the second is mounted after it. Modern manifolds are protected with a metal plate - before replacing it must be removed to gain access to the lambda probe (one or two). Use screwdrivers to remove the protective plate.

• Now warm up the car engine to a temperature of 80-90 degrees. This will make it easier to unscrew the old sensor (it sits tightly on the car). When heated, the metal expands slightly, which makes it easier to unscrew the part. There is no need to warm up the engine for a long time. The best option is to start the engine and wait until the temperature is 80-90 degrees, warm up the engine for a few minutes and turn off the ignition.

• Use a wrench to disconnect the negative terminal on the car battery. The nuts on the electrical components are not tightly tightened, so there should be no problems with their disconnection. As you loosen the nut, move the terminal to the side to completely disconnect the electrical components of the car.

• Find the lambda element on the exhaust system and carefully disconnect the electrical connector. The old oxygen sensor fits snugly, but not tightly, in the connector, so you can easily disconnect the device with a few hand movements. The connector should be moved to the side so that they are located at a distance of at least 20-30 centimeters from each other.

• Now the most difficult stage of work is being carried out - the actual dismantling of the device. To carry out the work, it is recommended to purchase a nozzle with an extension, which makes the work easier. Attach the nozzle to the lambda probe, rotate the nozzle counterclockwise to loosen the fastening. Take a wrench and loosen the nut on the exhaust pipe, and then carefully pull out the oxygen sensor.

• You can get rid of your old device – you won’t need it anymore. It does not contain any useful spare parts or components. Pick up a new lambda probe and treat its threads with any good lubricant (for example, it could be copper paste). The use of lubricant simplifies the installation of the device and also seriously reduces the risk of damage to the threads on the exhaust pipe.

• Now take the new sensor in your hands and secure it until it stops in the hole on the pipe. For installation, you do not need to use a nozzle with an extension - installation by hand will be sufficient. Use a wrench to tighten the nut to secure the part into the hole. But don't overdo it! If you overdo it, it will be difficult to remove the lambda element in the future, which will create many unnecessary problems.

• Connect the new part to the electrical connector leading to the engine. Take the “fork” end of the lambda probe in your hand, treat it with electronics cleaning spray and insert it into the motor electrical connector. It is recommended to fix the resulting structure with clamps. You can also put them on a special “shelf” made in the form of hanging hook-supports (all modern cars have them).

• At the final stage, reinstall the metal plate and connect the negative terminal to the battery. Reset the settings or update the memory on the electronic unit that controls the engine. You can reset the settings on the control panel or using a program on your smartphone, if your ECU supports such a function. To activate the sensor, remove the car from the overpass and drive it for several tens of kilometers. After this, the device will begin to function as usual.

It is recommended to carry out work wearing thick, clean gloves. Many parts of the exhaust system will be hot (gloves will help you avoid getting burned). Gloves will also help protect against electric current discharges at the stage of dismantling the terminal.

What are the advantages and disadvantages of Lambda Zone?

Like any chemical, this drug has both positive and negative sides.

pros

• Despite the vitality of this bloodsucker and the ability to mutate, the drug “lambda zone” is not addictive.
• The speed of the poison's effects. After just 6 hours you can see the first corpses of bedbugs, and after 5 the last individuals will die.
• When spraying, no odor is released, the suspension itself adds flavoring bases;
• The insecticide can be used for prophylaxis for up to six months.
• The effectiveness of lambda cyhalothrin after spraying is at least 60 days.
• Not hazardous to health for warm-blooded animals and humans.

Minuses

• The emulsion cannot be used to treat upholstered furniture or mattresses. As you know, bedbugs love to hide in such secluded, dark and warm places.
• The emulsion costs a lot - about 650 rubles.

Description:

Lambda is a substance with an insecticidal effect that belongs to the group of pyrethroids; there are several of its isomers. The active substance in an insecticide typically contains only two (1R cis ZS and 1S cis ZR) of the four possible stereoisomers of cyhalothrin. The active ingredient lambda-cyhalothrin has contact and gastric effects, as well as repellent properties. Lambda-cyhalothrin is a synthetic pyrethroid insecticide used to control a variety of pests on food/feed crops and livestock, and in and around buildings and structures. It is currently used on a wide range of pests (including aphids, adult Japanese beetles, grasshoppers and butterfly larvae) in a variety of applications. It can also be used for structural pest control (termiticide) and in public health applications to control insects (mosquitoes, cockroaches, ticks and flies) that may act as disease vectors. Other uses: An insecticide applied to the back of cattle to control lice and certain other parasites.

Application:

Lambda-cyhalothrin insecticide is used to control a wide range of insect pests in grains, hops, ornamentals, potatoes, vegetables and other crops. Provides good control of virus-infected insects at a level of 2-5 g/ha. It is used to control insect pests not only on agricultural land, but also in public and industrial premises.

Receipt:

The method for producing lambda-cyhalothrin includes stages in which 3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylic acid serves as the starting material, DMF is the catalyst, n-hexane is the solvent, and a hexane solution of 3- (2 ,2-dichlorovinyl)-2,2-dimethylcyclopropanecarbonyl chloride is prepared from n-hexane solution of 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarbonyl chloride, 3-phenoxy 4-fluorobenzaldehyde and sodium cyanide are hydrogenated in a condensation reaction to form the cyhalothrin condensation . The hexane solution, a composite catalyst, is directly added to the n-hexane solution of cyhalothrin and an epimerization reaction is carried out to produce lambda-cyhalothrin.

Effect on the body:

Lambda-cyhalothrin destroys pests either through physical contact with the chemical or when the active substance is ingested by the insect. This insecticide is the active ingredient of choice for many pest control manufacturers due to its long residual effect compared to other chemical ingredients. Lambda-cyhalothrin, like other pyrethroids, kills harmful insects by destroying and compromising the body's central nervous system. The insecticidal activity of lambda-cyhalothrin is thought to be due to interference with sodium channels in the insect nervous system, leading to paralysis and ultimately death. Paralyzed and unable to perform its normal physical functions, the insect dies of starvation. The poison spreads among insects from the affected insect to the healthy one, infecting and killing the entire colony.

Toxicological data:

Acute toxicity:

Oral LD50 – rat – 56 mg/kg

LC50 for inhalation - mammal - 4 hours - 60 mg/m3

LD50 when applied to the skin - rat - 632 mg/kg

Lambda-cyhalothrin acts on the neuromuscular system. It causes neurotoxicity in three animal species (rats, mice, and dogs); Neurotoxicity occurs in rats following oral, dermal and inhalation exposure. As with other pyrethroids, inhalation exposure is the most toxic route of exposure. The observed neurotoxic effects are classic pyrethroid effects and are toxicologically significant. Observed liver effects in some studies strongly suggest an adaptive response. Lambda-cyhalothrin is classified as "unlikely to be carcinogenic to humans" based on a lack of evidence of carcinogenicity in mice and rats. This classification was determined at the HIARC meeting of 03/01/2004. Developmental studies in rats and rabbits exposed to cyhalothrin. No developmental toxicity was observed in any of the developmental toxicity studies in rats and rabbits. Maternal toxicity as clinical signs of neurotoxicity in a rat study; thus, reductions in body weight gain and food intake were observed in studies in rats and rabbits. A 3rd generation reproduction study in which rats were administered cyhalothrin. In a 3rd generation reproduction study in rats, parent/offspring adverse effect levels (NOAELs) were similar based on parent and pup body weight loss and body weight gain.

The first 2 days of exposure in canine oral studies was the endpoint selected. The NOAEL used for the acute oral dose is 0.5 mg/kg, with the lowest observed adverse effect level (LOAEL) being 3.5 mg/kg. The endpoint chosen to assess chronic nutritional risk is appropriate because it is based on a chronic oral study in dogs. This NOAEL (0.1 mg/kg/day) is slightly lower than in canine studies with other pyrethroids; however, transient effects were observed at LOAEL 0.5 mg/kg/day. Short- and medium-term NOAELs are 0.1 mg/kg/day, based on clinical evidence of neurotoxicity at a LOAEL of 0.5 mg/kg/day. The NOAEL for dermal exposure is 10 mg/kg/day from a dermal toxicity study in rats and is based on clinical evidence of neurotoxicity at an LOAEL of 50 mg/kg/day. The NOAEL for inhalation exposure is 0.08 mg/kg/day in a rat inhalation study and is based on clinical evidence of neurotoxicity at a LOAEL of 0.90 mg/kg/day. No additional uncertainty factors (UF) were retained based on a HED impact level (MOE) of less than 100

Ecotoxicity:

Toxicity to fish LC50 - Oncorhynchus mykiss (rainbow trout) - 0.24 µg / l - 96.0 h

Toxicity to Daphnia and other aquatic invertebrates

LC50 – Daphnia magna (water flea) – 0.001 mg/l – 48 h.

Excess air coefficient λ

When analyzing engine performance, the term “stoichiometric ratio” is often used. It means the optimal ratio of oxygen and fuel, at which the prepared mixture burns completely. On the basis of this indicator, internal combustion engine modes and fuel supply features are calculated.

The ideal ratio is 14.7 to 1. It is clear that 14.4 kg of air does not enter the cylinder immediately, but within a certain time period.

The coefficient λ shows the ratio of the actual volume of oxygen entering the cylinder to the ideal parameter (indicated above). In simple words, it shows the deviation of the current amount of air from the optimal parameter.

Taking into account the obtained λ, three options are distinguished:

• 1 - ideal ratio;
• less than 1 - oxygen deficiency and excess gasoline;
• more than 1 - lack of gasoline and excessive amount of air.

Modern internal combustion engines are capable of operating in all cases, but deviations from the norm affect many parameters: acceleration, efficiency, reducing the concentration of harmful components, etc. It is optimal for the coefficient λ to be about 0.9-1.
