Pyrethrum vs Pyrethrin are insecticides extracted from certain species of flowers in the chrysanthemum family. Pyrethrins are the 6 active molecules – or esters – that act as the killing agent in the extract. Pyrethrum is the total extract from the flowers, while pyrethrins are the refined 6 esters.
What is Pyrethrum?
Pyrethrum powder is a natural insecticide derived from the flowers of the chrysanthemum (Chrysanthemum cinerariifolium) plant. Native to Chian, this beautiful flowering plant has been used for centuries for its potent insecticidal properties. The active ingredients in pyrethrum, called pyrethrins, are responsible for its effectiveness as a pesticide.
Pyrethrins work by targeting the nervous systems of insects, effectively paralyzing them and leading to their eventual death. The key advantage of pyrethrum over synthetic pesticides is its relatively low toxicity to mammals, birds, and fish, making it a safer choice for both humans and the environment.

How Long does Pyrethrum spray last
In soil, the pyrethrins (which make up pyrethrum) have a half-life of around 10 days under aerobic soil conditions and around 86 days in anaerobic conditions. Remember, pyrethrum is one of the shortest acting insecticides, manufacturers always state a 'best case scenario' under ideal conditions.
Pyrethrum vs. Pyrethrin: What's the Difference?
