How do pesticides kill insects? Is it safe for people or pets to inhale pesticides?

Pesticides are often used when insects such as flies or cockroaches are present in the home.SLEEP COOL insect killer supplier Why can pesticides kill insects? Does it work with all kinds of bugs? Also, is it safe for people and pets to inhale pesticide ingredients?

After spraying, insects become sluggish or twitch their legs until they die. Insecticides can be sprayed directly on insects or filled with smoke. There are many kinds of pesticides, but the active ingredients are basically the same. Chinese EASY ON Spray starch manufacturer Based on the functional sites (loci) of the active ingredient, there are 29 known functional sites.

Makes the transmission of nerve signals abnormal

In the insecticides used for mosquitoes and flies, the most commonly used ingredient is a substance called pyrethroids.Chinese EASY ON Spray starch supplier Pyrethroids enter the body through the insect's skin and air valves (holes that take in oxygen) and attach to parts of nerve cells called "sodium channels."

Sodium channels are channels used to absorb sodium ions into the interior of nervous system cells. Nerve tissue cell culture has the function of transporting charged particles such as sodium ions into and out of cells. Through students' good control and management of this social function, electrical signals can be effectively transmitted.

Normally, sodium ion channels are only opened when nervous system cells are excited (when they transmit signals). But when pyrethroids are attached to the channel, the channel will always be open and working, and the nerve tissue cells will always be in an excited state. As a result, the insect's body can go into convulsions and eventually develop even more immobility.

Another common insecticide used at home is organophosphorus insecticides. When nerve cells send signals to other nerve cells, neurotransmitters such as acetylcholine are secreted in the Spaces between nerve cells. Acetylcholine breaks down rapidly under normal circumstances. However, when organophosphorus pesticides attach to the enzyme that breaks down acetylcholine, it prevents the normal breakdown of acetylcholine. In this way, acetylcholine remains in the space between nerve cells, which makes the excited state of nerve cells impossible to stop, resulting in the gradual death of the insect.

In addition, the common ingredient in traps to catch cockroaches and ants is fipronil. Fluoride attaches to "GABA receptors" that inhibit the excitatory function of nerve cells. In this way, since the excitement cannot be suppressed, the nerves will continue to be excited, and the result will be death.

Just like this, the insecticide composition acts on various parts of the insect's nerve cells, making the nerve transmission abnormal and killing them off.
