Cyhalothrin is a pyrethroid insecticide, an ingredient in the Karate brand of pesticides sold by Syngenta^{[citation needed]}.

Cyhalothrin is a fluorinated pyrethrin analog.^[1]

Lambda-cyhalothrin is a mixture of highly active isomers of cyhalothrin.^[2] Brand names include 'Karate', 'Kung-fu', 'Matador', and 'Demand CS' (Syngenta); in the USA, 'Triazicide' and 'Hot Shot' are used in the Home Landsape and Garden markets^[3][4][5] Home Depot carries a brand of the insecticide under the brand name Real Kill. Terro also makes an outdoor ant and other insect prevention treatment similar to Home Defense using this ingredient. Sygenta held the patent for Lambda-cyhalothrin. This patent expired in most major markets in 2003.^[6]
