How safe is pyrethrum?
Pyrethrum is a biodegradable, water based concentrate derived from chrysanthemum flowers. The solution is EPA registered and has been approved for food processing plants, restaurants and sensitive applications such as the post harvest treatment of fruits and vegetables. Pyrethrum decomposes harmlessly leaving no oily residue like other chemicals or synthetic compounds that can be dangerous to humans and pets.
Pyrethrum is an insecticide and should be used as directed in the labeling. It has a low toxicity, it is water based, and biodegradable. The chrysanthemum flower uses this insecticide ingredient to protect itself from plant eating insects. As with any insecticide, never spray it directly on people or pets.
