Description

Allethrins are a group of synthetic pyrethroid insecticides known for their rapid knockdown effect against a wide range of flying and crawling insects. This product, Allethrins CAS NO 3972-20-1, is valued for its high efficacy and relatively low mammalian toxicity, making it a key active ingredient in various pest control formulations. It is essential for manufacturers in the public health, household, and agricultural sectors seeking reliable insecticidal solutions.

Application

• Household Insecticides: Primary active ingredient in aerosol sprays, mosquito coils, electric vaporizer mats, and plug-in devices for controlling flies, mosquitoes, and other household pests.
• Public Health Programs: Used in space sprays and fogging formulations for mosquito and fly control to combat vector-borne diseases.
• Agricultural Pest Management: Applied in certain crop protection products for the control of aphids, thrips, and other soft-bodied insects, often in greenhouse settings.
• Animal Health: Incorporated into pet care products such as shampoos, sprays, and collars for flea and tick control.
• Stored Product Protection: Used to protect grains and other stored commodities from insect infestation.
• Industrial & Institutional (I&I): Formulated into products for pest management in food handling areas, warehouses, and commercial facilities.
