Inhaling pesticides is safe for people or pets. How do pesticides kill insects?

It is common to use pesticides to control insects such as flies and cockroaches in the home. fly killer Why do pesticides kill insects? Do they work with all kinds of bugs? And can people and pets inhale pesticide ingredients?

After spraying, insects become sluggish or twitch their legs until they die. cockroach insecticide spray Insecticides are sprayed directly on insects or filled with smoke. There are many kinds of pesticides, but the active ingredients are the same. 29 functional sites (loci) of the active ingredient have been identified.

Affects nerve signal transmission

The most common ingredient in insecticides for mosquitoes and flies is pyrethroids. mosquito killer Pyrethroids penetrate the insect's skin and air valves (holes that take in oxygen) and attach to sodium channels in the nerve cells.

In nerve tissue cell culture, charged particles such as sodium ions are transported within and outside of cells. Sodium channels are channels that transport sodium ions into the interior of nervous system cells. Electrical signals can be efficiently transmitted when students are able to control and manage this social function effectively.

As a rule, sodium ion channels are only opened by nerve cells when they are stimulated (when they transmit signals). However, when pyrethroids are attached to the channel, it will remain open and functioning, and nerve cells will remain excited all the time. In turn, the insect's body may go into convulsions and become even more immobile as a result.

Organophosphorus insecticides are a commonly used form of home insecticide. These pesticides disrupt the normal breakdown of acetylcholine, a neurotransmitter that is secreted in the spaces between nerve cells. This leads to an accumulation of acetylcholine, which causes nerve cells to remain in an excited state and ultimately results in the 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. Thus, as the nerves cannot be suppressed, they will continue to be excited until death occurs.

In the same way, the insecticide composition acts on different parts of the insect's nerve cells, causing abnormal nerve transmission and causing the insect to die.
