Why do eco-friendly 'insecticides' kill insects? Is it harmful to the human body?

Environmental medicine is a good auxiliary means of pest control in daily life

The hot, humid summer months are ideal for mosquito breeding. VITFE insect killer supplier Common vector mosquitoes, such as the Asian tiger mosquito and Aedes aegypti, can transmit diseases such as Japanese encephalitis and dengue fever. In order to prevent and control the infestation of mosquitoes and cockroaches, the average person will often use electric mosquito coils, mosquito coils and other easily available products, you can see the municipal office along the street drainage holes sprayed with insecticides.

Electric mosquito-repellent incense and insecticides, which are indispensable chemical weapons for the development of daily learning and life, SLEEP COOL insect killer manufacturer are the so-called "environmental drugs". But how much can you know about these ubiquitous chemicals? What are the effects of environmental drugs on human health? What changes will it bring to the environment?

For insects, pesticides are nerve gas

Insecticides can be divided into three grades according to their ability to cause halo: strong fast-acting drugs, medium fast-acting drugs, slow acting drugs.

A large class of chemicals used in highly effective and environmentally friendly medicines are pyrethroids, which are structurally similar to pyrethroids that can be extracted from specific chrysanthemums, usually ending in -thrin, which translates to Oo Ning in Chinese. Common compounds include mefluthrin, Prallethrin, Cyphenothrin and so on.

The middle structure of the three compounds is similar, but there are differences between the two sides. Chinese EASY ON Spray starch In fact, it is the difference between these two "substituents" that makes the drug work slightly differently.

Pyrethroids kill mosquitoes more effectively than drugs such as camphor and menthol because they have an axon-stimulating toxin that enters the insect's body and opens sodium channels in the insect's cell membrane, increasing conduction and causing overstimulation of the nervous system that eventually paralyzes and kills the mosquito.

Pesticides smell so bad, shouldn't they be bad for you?

At this point, there must be some concern: Should substances that can kill mosquitoes also cause harm to humans? Of course, manufacturers have taken this into account, and one of the key points of environmental drug development is trying to target only the target organism. In terms of insecticides, pyrethroids are extremely toxic to arthropods, but less toxic to Vertebrata such as humans.

Even so, if the skin is exposed to high concentrations of pyrethroids or pyrethroids over a short period of time, itchiness, burning or tingling may occur. If high concentrations of pyrethroids or pyrethroids are inhaled or ingested over a short period of time, it may cause dizziness, headache, and even loss of consciousness. Therefore, everyone should pay attention to the amount of medication in the environment and keep ventilation.

When spraying insecticide indoors, be sure to maintain air circulation in the house

It is often said that "natural pyrethroids are good". However, natural pyrethroids derived from pyrethroids are actually more toxic than synthetic pyrethroids, the reason being that naturally derived pyrethroids actually contain six different compounds, all of which have insecticidal effects. When the body ingests naturally extracted pyrethroids, the liver must first take the time to break the long carbon chain of natural pyrethroids, making the blood more toxic. Unlike synthetic pyrethroids, natural pyrethroids can also trigger allergic reactions in humans and even cause asthma in the case of prolonged exposure.

While pyrethrins are less toxic to most mammals, they are highly toxic to cats! Because cats lack the enzymes necessary to break down pyrethrin. So, if you have a cat at home, pay special attention to using it.
