Question 3

How does Pyrethrum work?

Accepted Answer

Neurotoxic Mechanism

The active constituents within this botanical extract function as potent neurotoxins specifically designed to affect invertebrates. When insects come into contact with the ingredient, the chemicals penetrate their system and begin to disrupt the normal transmission of nerve impulses.

Impact on the Nervous System

This compound works by overstimulating the nerve cells of the target pest. This interference prevents the nervous system from functioning correctly, leading to a series of physiological failures. This action results in paralysis and death for the insect:

Rapid loss of coordination

Muscular paralysis

Eventual mortality

While it is highly lethal to pests like lice, it is generally considered to have lower toxicity in humans because mammalian systems can often break down the chemicals more efficiently. However, it may still act as a skin or respiratory irritant in sensitive individuals.
