These ingredients include:
- alpha-Cypermethrin
- beta-Cyfluthrin
- Bifenthrin
- Cyfluthrin
- Cypermethrin
- d-Allethrin
- d-phenothrin
- Deltamethrin
- Esfenvalerate
- Etofenprox
- Fenpropathrin
- Flumethrin
- gamma-Cyhalothrin
- Imiprothrin
- lambda-Cyhalothrin
- Momfluorothrin
- Permethrin
- Prallethrin
- Resmethrin
- Tau-fluvalinate
- Tefluthrin
- Tetramethrin
- Tralomethrin
- zeta-Cypermethrin

Additional Pyrethroid Facts
- Pyrethroids strongly bind to sediment and other natural materials in water bodies, which limits bioavailability to non-target organisms.
- Pyrethroids protect the nation’s food supply by helping farmers control pests that threaten a wide range of important crops.
- Manufacturers of pyrethroids promote the responsible use of their pesticides through stewardship programs aimed at growers, consumers and professional pest control applicators.
- Pyrethroids are widely used in products for agricultural, vector control (e.g. mosquitoes), animal health, stored grain, home and garden, and turf and ornamental markets.
