Cockroaches, mosquitoes, ticks and bedbugs - all these harmful insects can significantly complicate life and cause many problems. A huge number of chemicals have been developed to control pests. Some contain the active substance cypermethrin. But is it possible to use such drugs without fear for the he alth of loved ones? We need to figure out what cypermethrin is and how it can affect human he alth.
"Cypermethrin": the impact on humans of a universal insect repellent
The appearance of annoying insects in residential premises not only causes a lot of inconvenience to residents, but also poses a potential threat to he alth. Bed bugs and mosquitoes do not make it possible to sleep, their bites itch quite strongly and can cause allergies. Ticks and cockroaches are carriers of dangerous diseases.
Get rid of these"neighbors" is very difficult. For these purposes, special insecticidal preparations are often used. Insecticides contain active substances that kill insects, as well as auxiliary components designed to mask unpleasant odors and are used to achieve the desired consistency. Now insecticides, which include cypermethrin, are quite common. The effect on humans of this component is classified as a third hazard class.
Principles for choosing pesticides
When choosing means for the extermination of harmful insects, you need to take into account your own requirements and some other points:
- The effectiveness of the drug. It depends on whether the tool can cope with the task.
- Duration of action. It will indicate the speed of disappearance of parasites and the duration of the use of the drug for preventive purposes.
- Principles of application. Everyone chooses the tool that is most convenient for use.
- Features of the vital activity of insects. For example, bedbugs lead a special lifestyle, and many drugs do not have the desired effect on them.
- Availability of processed household items. When processing residential premises, tools that act directly on objects are suitable; in non-residential premises, traps and baits can be placed.
- Smell persistence. Do not choose pungent-smelling and poorly weathered preparations.
- Safety for humans and pets, if any.
If the drug is planned to be usedin open space for a short time, you should choose low-concentration repellents, if necessary, the treatment can be repeated. Only licensed insect repellents must be used, which must indicate the registration number and the organization that issued it; active ingredient and its concentration; possibility of application directly on the person.
All requirements are met by products in which the active ingredients are cypermethrin and permethrin, the impact on human he alth is minimal.
Cypermethrin is a universal insecticide
Cypermethrin is a third-generation pyrethroid substance that can be produced in various forms:
- concentrated emulsions containing 5-25% active substance;
- powders to be moistened or dissolved;
- tablets.
Properties of "Cypermethrin"
"Cypermethrin" looks like a viscous transparent liquid from light yellow to brown, with a slight specific odor. The substance consists of eight types of isomers. Some effectively destroy flying insects, others - crawling ones. The advantages of "Cypermethrin" include resistance to ultraviolet rays and an acidic environment. In addition, the substance is easily neutralized by alkaline solutions.
How "Cypermethrin" affects insects
The third generation repellent "Cypermethrin" is insecticidal-acaricidal agent that affects the nervous system of insects and larvae. The drug is not capable of damaging laid eggs.
Retains activity for 30 days from the date of application. However, the substance has the highest efficiency within 24 hours. According to observations, addiction to the drug has not been identified.
Drug toxicity
The toxicity of the drug "Cypermethrin", whose effect on humans and warm-blooded animals is determined by the method of contact, is classified as follows:
- The second class of highly dangerous solutions include solutions of 0.1% concentration in the form of a spray, which have an acute biocidal property. Such drugs are prohibited for use in hospitals, preschool and school institutions, sanatoriums, recreation centers, catering establishments and residential premises;
- To the third class of moderately dangerous include those drugs with subacute biocidal action. It can be used in any premises with strict adherence to the rules of use: compliance with permissible consumption rates, ventilation of the premises and wet cleaning with alkali after treatment, the absence of people and animals in the room at the time of disinfection.
- 4 class of low hazard involves the application of the drug to the skin or clothing. Use is permitted without restrictions. If the product is applied to the skin repeatedly, slight irritation may occur.
Using the drug
"Cypermethrin",instructions for use which involves the preparation of a solution of the required concentration, used against synanthropic insects: cockroaches, flies, fleas, bed bugs, ants and mosquitoes in technical rooms, in apartments and houses (except for rooms for sleeping and playing children), in hospitals and sanatoriums (except for wards for patients), in catering establishments. It can also be used in natural conditions: open water bodies, sanatorium green areas, playgrounds to fight mosquitoes, ixoid ticks and fleas.
"Cypermethrin": instructions for use against mosquitoes
To fight mosquitoes, a 0.01% solution is prepared, which is used to treat mosquitoes in the house, facades of buildings and internal walls of garbage bins - places where bloodsuckers hide in hot weather.
To destroy mosquito larvae, in their breeding grounds (basements and closed reservoirs), periodically, not more than once a month, they are treated with a solution at the rate of 25 ml per m2 surface or the water surface.
"Cypermethrin": instructions for use from cockroaches
Prepare an aqueous emulsion with a concentration of 0.1% and apply to interior items in places where pests accumulate and on their way to moisture and nutrition: thresholds, crevices along door frames, baseboards, areas around them and all hard-to-reach places.
The amount of the drug is calculated based on the calculation:
- when applyingon plastic, glass and ceramic surfaces - 50 ml per m2;
- when applied to plywood, wood, concrete and other surfaces that can absorb liquid - 100 ml per m2.
All rooms where cockroaches have been detected are processed simultaneously. Killed and immobilized pests should be regularly removed and destroyed.
"Cypermethrin" from bedbugs: instructions for use
Use an aqueous solution of the drug with an active substance concentration of 0.01%. Cracks on walls and interior items, beds, sofas, crevices in skirting boards are processed. Substance consumption - 50 ml per m2 on the territory of at least 30 m2. Spraying is carried out at a temperature not lower than ten degrees. After fifteen minutes, the room must be ventilated for half an hour and the surfaces washed using a soap and soda solution.
It is forbidden to apply the drug on bed linen.
"Cypermethrin": instructions for use from ticks
The territory is cleared in advance of grass and needles - places where blood-sucking insects accumulate. Cultivated areas should be closed with a fence with a diameter of 50-100 meters and visitors should not be allowed during the week. Weather conditions must also be taken into account, because rains reduce the effectiveness of the drug.
The product remains effective for 30-45 days, depending on the weather. Repeatedprocessing is carried out as insects appear.
Effect of the drug on humans
With frequent contact with the drug "Cypermethrin", the impact on human he alth can be expressed by nausea, headache, muscle weakness, salivation, shortness of breath and convulsions. The substance breaks down in the body to carboxylic acid molecules and is excreted in the urine. He alth monitoring is carried out by measuring the level of metabolites in the urine. Quantitative indicators of the active substance in the blood or plasma indicate intoxication.
What to do in case of poisoning
As a result of a violation of precautions or an accident upon contact with the drug, acute poisoning may occur, which is expressed by the presence of an unpleasant taste in the mouth, weakness, vomiting, headache and nausea, which is aggravated by smoking or eating, pain in the abdomen, irritation of the respiratory tract, profuse salivation in the form of foam.
What to do in case of acute poisoning? What effect does Cypermethrin have on a person? The antidote must be taken immediately:
- If the product got through the lungs, by inhalation of vapors - you need to take the victim outside, remove contaminated things from him, let him rinse his nose and mouth with soda solution and drink one or two glasses of adsorbent (3 tablespoons of polysorb or activated carbon - 10 -12 per cup).
- After accidentally swallowing the drug, you should immediately drink one or two glasses of water with an adsorbent. If the victim has lost consciousness, he should not be injected intomouth foreign objects and induce vomiting.
- The product got on the mucous membrane of the eyes. It is necessary to rinse with a soda solution for several minutes and drip with a solution of sodium sulfacyl (for example, albucide).
- If a drop of substance gets on the skin, it must be carefully removed with a cotton pad or rag and washed with soapy water.
- After giving first aid, the victim must be sent to the hospital.
Danger for children
The safety of Cypermethrin, whose influence on humans was considered minimal, was refuted by French scientists, who proved that the drug has a negative effect on the development of young children. This is manifested in a slowdown in brain activity, memory impairment and the ability to perceive and assimilate words.
What research scientists show
Researchers believe that children suffer more than adults because they spend more and more time on the floor and taste objects that fall into their hands. This makes babies more vulnerable to pyrethroid drugs that enter the body through the skin and gastrointestinal tract.
Harmfulness for babies of the substance cypermethrin, whose effect on a person is negative, was proved by studies of the urine of the children who took part in the experiment. It revealed metabolites of insecticides used in everyday life. In cases where the concentration of decay products of toxic substances was the highest (although modern toxicologists consider this to be a low indicator), children were observedimpaired speech perception.
However, scientists have not identified a specific link between insecticides and brain development in children under the age of six. They cannot determine exactly how poisons affect the body.
Also, experts have data on the effect of toxic substances contained in repellents on sperm activity and the development of leukemia in babies.
To avoid undesirable consequences, it is necessary to strictly follow the instructions and, if possible, not be present during the persecution of insects in the treated premises. After treatments, everything must be thoroughly washed with an alkaline solution, especially places accessible to small children.
