• Why do environmental pesticides kill insects? Is it bad for you?

Electric mosquito-repellent incense, pesticides, these indispensable chemical weapons in daily life, is the so-called "environmental medicine". VITFE insect killer supplier However, how much do 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, SLEEP COOL insect killer manufacturer medium fast-acting drugs, slow acting drugs.

Pyrethroids are a large class of chemicals used in powerful, fast-acting, environmentally friendly medicines. The structure of this compound is very similar to that of pyrethrin, which can be extracted from specific chrysanthemums. Common compounds such as cyfluthrin, proparthrin, cypermethrin, etc.

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? Chinese EASY ON Spray starch 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 humans.

However, if the skin is exposed to a high concentration of pyrethroids or pyrethroids in a short period of time, it may feel itchy, burning or stinging. If the skin is inhaled or ingested a high concentration of pyrethroids or pyrethroids in a short period of time, dizziness, headache, and even loss of consciousness may occur. Therefore, people should use environmental drugs or pay attention to the dosage. Keep it ventilated.

It is often heard that "natural pyrethrin is better", however, the toxicity of natural pyrethrin extracted from pyrethrin is actually stronger than the pyrethrin toxicity synthesized by artificial intelligence, because the natural pyrethrin actually contains six different compounds, these compounds have insecticidal effects, when the human body ingested natural pyrethrin, The liver must first take time to break down the long carbon chains found in natural pyrethroids, so that the toxicity of Chinese blood can increase. In contrast to synthetic pyrethroids, natural pyrethroids can also cause allergic reactions in humans, and even asthma in cases of prolonged exposure.

While pyrethrins are less toxic to most mammals, they are highly toxic to cats! Cats lack the enzymes necessary to break down pyrethroids. So pay special attention if you have a cat in the house using words.

Pesticides only kill insects. Is it really that amazing?

Because the principle of pyrethrin's action is related to nerve excitation, it is theoretically toxic to most organisms, the difference is the amount that can be tolerated. Pyrethrin is highly toxic not only to cats, but also to aquatic life. Take cysteamine as an example. Most have only 5ppb of cysteamine LCt50, which is already highly toxic to fish. So when spraying, the aquarium should stop pumping and cover the box to prevent pesticides and aerosol particles from falling to the surface of the water.

Pay attention to the instructions and keep it ventilated

There are thousands of environmental drugs, each used differently. The most direct way to understand the use and precautions of these drugs is to read the instructions on the back of the product. Take the common electric mosquito repellent incense as an example, the label indicates "this preparation is toxic to aquatic organisms, please do not pollute or use in fish ponds, water sources, ponds, lakes, rivers and other waters."

In the use of the process, but also pay attention to "open the doors and Windows to maintain air circulation", to avoid human exposure to high concentrations of the environment. In addition, be careful not to deploy and re-sell agents on your own, so as not to accidentally hurt yourself and your family while eliminating mosquitoes.
