What is the difference between the active ingredient in (Cyfluthrin) and (Cypermethrin)?

Answer:

Cyfluthrin belongs to a class of insecticides known as synthetic pyrethroids. Synthetic pyrethroids are man-made insecticides created to mimic the chemical properties of the naturally-occurring insecticide pyrethrum, which comes from the crushed petals of the Chrysanthemum flower. Synthetic pyrethroids, like cyfluthrin, are often preferred to the real thing as an active ingredient because they offer the added bonus of remaining effective for longer periods of time, sometimes up to 3 months.

Cypermethrin belongs to a class of insecticides known as synthetic pyrethroids, found in Cynoff EC, Cynoff WP, Cyper TC Termiticide, Cyper WP, and Demon WP pesticide concentrates. Synthetic pyrethroids are man-made insecticides created to mimic the chemical properties of the naturally-occurring insecticide pyrethrum, which comes from the crushed petals of the Chrysanthemum flower. Synthetic pyrethroids, like cypermethrin, are often preferred to the real thing as active ingredients because they offer the added bonus of remaining effective for longer periods of time.

They are very similar. The differences usually depend on the products themselves.
