pyrethrin

Pyrethrin is a natural chemical compound derived from chrysanthemum flowers, used as an insecticide to control pests like flies, mosquitoes, and lice. It works by blocking nerve signals in insects, causing paralysis and death quickly without lingering toxicity. Pyrethrins are often found in sprays, pet shampoos, and crop protectants. While effective against insects, they break down rapidly in sunlight and environment, reducing environmental impact. Due to their natural origin and quick action, pyrethrins are considered relatively safe for humans and pets when used as directed, but should still be handled carefully.
