Whats the difference between pyrethrin, pyrethrum and pyrethroid?
Pyrethrum is the overall name of insecticides derived from the chrsysanthemum family of flowers. Pyrethrins are the organic compounds from these flowers that serve as neurotoxins that attack the nervous systems of flying insects. Pyrethroids are synthetic (man-made or altered) forms of pyrethrin that enhance the toxicity and effects of the insecticide. The most popular form is known as permethrin. The Skeeter Defeater contact insecticide contains pyrethrin, a botanical insecticide.
