Now I have settled on the product Cypermethrin for bed bugs, how long after the treatment the bed bugs die is the most important question for me. I don't want history to repeat itself. Then the insects multiplied a lot, and I kept waiting for the result after the treatment. Now I want to understand how long it takes to completely destroy the pests. So far I am considering only Cypermethrin, so please tell me exactly about this drug. Thank you.
The author of the portal answers the question:
In my material below, you how to properly use Cypermethrin against bed bugs and how to follow safety precautions .
Cypermethrin for bed bugs - mechanism of action
It is the active ingredient in the composition of the product of the same name. It has no systemic action, but it promotes the death of pests when the cuticle (chitinous shell) or digestive system is affected. Cypermethrin is considered one of the best of its kind (from pyrethroid class). This substance helps to disrupt the movement of sodium ions.
The result is complete paralysis, the insect cannot perform its basic functions, and soon dies.
What are pyrethroids. How effective are
These are analogues of natural insecticides - pyrethrins. The principle of action of all preparations of this type is the same - they inhibit the function of the nervous system. The higher the dose of the main chemical, the faster will die pests. When properly treated, pyrethroids provide what is called a knockdown effect. This means that the bloodsuckers die instantly. The likelihood of reinfestation is reduced because the bed bugs receive a maximum dose of poison.
There are poisonous substances (pyrethroids) of 3 groups: first, second and third generation. They differ in structure and properties. The level of effectiveness also often varies. However, not always the last generation (more modern) means are better than the previously created ones. For example, cypermethrin just belongs to the group of means of the 2nd generation. It differs from the first and third generation analogues by its low consumption rate, which does not reduce the effectiveness.
The disadvantage of cypermethrin is its toxicity to bees and fish.
How synthetic pyrethroids work
Drugs of this group act on the process of transmission of nerve impulses. This is facilitated by disruption of the sodium ion current, changing the function of the sodium channels. They open and close much slower than in the normal state. As a result, the flow of sodium ions is also inhibited. As a consequence of this process, depolarization occurs, which provokes repeated discharges. This creates conditions for synaptic disturbances.
In addition, pyrethroids also disrupt calcium ion metabolism. This contributes to an increase in the amount of acetylcholine during the passage of the nerve impulse through the synaptic cleft.
As a result, there is a simultaneous disruption of a number of processes, which does not allow parasite The patient is unable to move and eat, he has no control over his body, and he quickly dies.
Can insects adapt to pyrethroid preparations
Earlier sources (2003) suggested that there was no risk of developing resistance in insects to this class of poisons. However, it was not confirmed; with time, practice showed that pyrethroids and cypermethrin, in particular, can cause persistent resistance in bedbugs. And it is acquired - it appears as the frequency of using the substance increases. Gradually more and more insecticide is required.
As a result, a dose of poison that is tens of thousands of times greater than the original dose becomes sufficient to kill the pests.
There is also a risk of developing cross-resistance. This means that resistance to certain poisons in insects increases even when using some completely different substances, which is due to internal processes that develop in this case. The main mechanism lies in the peculiarities of enzyme functioning. At the same time, some of them more strongly deactivate the poisonous substances.
Synergists can be used to increase the effectiveness of cypermethrin as well as other pyrethroids. These are substances that help to increase the strength of action of insecticides of some species. They are not poisonous, but act as inhibitors of enzymes that are responsible for enhancing the action of pyrethroids.
Synergists are usually used in conjunction with insecticides of this class.
What is the difference between pyrethroids and pyrethrins
The use of natural poisoning agents provides a sufficient level of treatment efficacy. However it is possible to increase it additionally. Synthetic analogues are used for this purpose, they were developed taking into account the properties of pyrethrins. However, cypermethrin as well as many other pyrethroids are superior to natural insecticides by more than 900 times.
This is due to the aggressive action on bed bugs, rapid penetration into the body through the external skin. However, the level of toxicity of the preparations is also much higher.
Russian insecticidal agents based on cypermethrin
Their number is quite large. And such preparations differ in composition (they may contain other pyrethroids, components of other classes and synergists). Cypermethrin from bed bugs works quickly and reliably. If there is no possibility to buy it, other options are considered:
- Tetrix - two-component preparation, contains cypermethrin and methafos. This increases the efficiency of treatment. Tetrix is a professional product and costs more than analogues.
- Cucaracha also refers to two-component preparations, containing cypermethrin and malathion. These substances represent different classes of poisonous substances, respectively: pyrethroid and organophosphorus compound.
- Zifox. By composition and dosage such a drug is a direct analogue of the drug in question. Accordingly, the principle of action is the same as the properties.
- Sichlor contains 10% cypermethrin and another 20% chlorpyrifos. The preparation provides high treatment efficiency because these substances act in different ways.
- Cipaz Super. This is another direct analogue of Cypermethrin 25 and Cifox, it does not differ in composition and properties. The main component is the same. The concentration of cypermethrin in the means Sipaz Super is 25% insecticide, produced in a container - a bottle of 1 liter.
- Dichlofos Neo. This is a more effective remedy, containing 3 substances that belong to the same class of poisoning agents (cypermethrin, tetramethrin and permethrin).
- Clopomor. Its main components are cypermethrin and permethrin. The action of insecticides enhances the synergist piperonyl butoxide.
- Clean House. It is a two-component product. The active ingredients are permethrin and cypermethrin. The action of both is enhanced by piperonyl butoxide.
- FAS Cypermethrin 25 is a direct analog of the drug in its composition. The dosage of the active component is the same, so the principle of action is similar.
Goods from the USA
Some of the drugs are not yet available on the market in the Russian Federation. They are ordered through Internet resources. Such preparations also contain cypermethrin, and sometimes also components of other types (also from pyrethroid class). This group includes:

Composition and product forms
Initially, the substance cypermethrin is produced in powder form. However, a drug containing this component reaches the consumer in the form of a concentrated solution. In this case, the highest level of efficacy is provided. It gets rid of bed bugs and other insects quickly. You can also find the product in the form of tablets - they are used to treat the premises on the principle of a smoke bomb. You can buy the concentrate in bottles of 50 ml and 1 liter.
Cypermethrin for bed bugs - instructions for use
Smoke bomb cypermethrin-based is not recommended for use in the apartment - smoke spreads outside the dwelling, through windows and doors. Neighbors may mistake it for the consequences of a fire and call for appropriate help. It is better to use cypermethrin concentrate, instructions for use against bed bugs:
- The room is prepared: a general cleaning is performed, large furniture is moved, opening up access to hidden areas. Such measures provide many opportunities to increase efficiency: they help to remove dust, which will improve the quality of treatment of the room; they also detect bedbugs' nests.
- Take off the bedding, remove things from the closets. All woven items should be washed or otherwise treated in a safe way.
- Roll up the carpeting or bend the edges so that you can spray over it.
- The walls are cleared of interior objects.
- The product should be diluted according to the manufacturer's recommendations. Different concentrations (10 and 25%) are added to water in different dosages.
- The bed bug repellent Cypermethrin is applied by spraying, which is a more effective method than applying it with a sponge. Windows and doors must be closed. The duration of exposure to the active ingredient immediately after treatment is several hours.
- The drug continues to work for 15-20 days, so re-spray it at the end of this period.

Safety precautions when working with insecticide
Concentrates are used to prepare an aqueous solution. In this case it is sprayed over the surfaces, for which you should buy a sprayer in advance. In this case, you should first wear personal protective equipment. Obligatory is the use of goggles that cover the eyes, polymer gloves (not woven, which is important), clothing with long sleeves, pants, scarf and respirator. After work, you should wash your clothes and shower using soap, since the insecticide breaks down in an alkaline environment. Mouth and nasal passages should be rinsed with water.
Effects of the drug on humans
Cypermethrin is a substance of Hazard Class 3. It can cause harm only if the instructions for use are grossly violated. In other cases, the drug does not provoke unpleasant symptoms.
This is due to the fact that the poisoning substance, once in the body of warm-blooded creatures, is quickly metabolized, and the released components are rapidly eliminated.
What to do if you are poisoned. First aid
If the instructions for use are not followed, there is an increased risk of adverse effects. This can cause headaches, dizziness, nausea, vomiting, and weakness. These are signs of intoxication with the poisonous substance. If cypermethrin enters the respiratory tract, you should go to the emergency room of the hospital in-patient department. If you come in contact with the agent through the exterior (when there are injuries), it is recommended to wash them with a soap or soda solution.
Sorbents are taken if the substance has entered the digestive tract (with food).
Pros and cons
The drug in question has a number of positive qualities:
- high efficiency;
- simple principle of application;
- Low risk of resistance (if the recommendations for use are followed - the drug is alternated with other agents);
- low level of toxicity;
- absence of a pronounced odor;
- versatility.
