Is pyrethrum a safe organic pesticide?

No. Pyrethrum is a relatively low toxicity natural insecticide and since it breaks down quickly, generally has low environmental impact as well. For these reasons it enjoys a reputation of being “safe”. Pyrethroid insecticides, on the other hand, are generally more toxic, more environmentally persistent and therefore not as “safe”.

How does permethrin kill?

Permethrin kills by acting as a high-power poison to the central nervous system. Once poisoned, the insect’s nerve cells become excited, causing paralysis and preventing normal feeding and grooming activities. Absence of these activities leads to the insect’s eventual or immediate death.

What is pyrethrum insecticide?

Pyrethrum is a contact insecticide, which means the chemical must touch the insect to kill it. Pyrethrum is used in head lice treatments, spray insecticides, bug bombs, foggers and flea sprays. It’s one of the least poisonous commercial pesticides available, primarily because it breaks down fast in the environment and in the human body.
