Type: Insecticides
Mode of Action: Disruption of the nervous system
Common Product Names: Pyganic, Stryker, Riptide
What is it?
Pyrethrins are natural compounds extracted from chrysanthemum flowers, specifically the species Chrysanthemum cinerariifolium. These compounds have been used for centuries due to their potent insecticidal properties. They are considered relatively safe for humans and pets when used as directed, making them a popular choice for both agricultural and residential pest control.
How does it work?
Pyrethrins rapidly affect the target insects by disrupting their nervous system functions. The insect experiences paralysis and dies shortly thereafter. The effectiveness of pyrethrins is usually observed almost immediately upon contact with the insect, with noticeable results within minutes to hours. However, because pyrethrins break down quickly in the environment, they do not provide long-lasting residual protection, which necessitates repeated applications for ongoing pest control.
