What is pyrethrum?
Pyrethrum is a natural plant product that is produced by the pyrethrum daisy, Tanacetum cinerariifolium, a member of the Asteraceae family. It is concentrated in the flower head. The active substance is six esters known as pyrethrins which work in combination to kill insects. Pyrethrum is a unique insecticide in that, used correctly, it is safe for use near humans and warm blooded animals, in kitchens and restaurants, food processing factories and other sensitive environments. It also breaks down quickly, especially in sunlight, and is non-persistent in the environment. |
