Cyfluthrin is a synthetic pyrethroid derivative that is used as an insecticide. Like most pyrethroids, it is highly toxic to fish. It is generally supplied as a 10-25% liquid concentrate for commercial use and is diluted prior to spraying onto agricultural crops and outbuildings. Excessive exposure can cause nausea, headache, muscle weakness, salivation, shortness of breath and seizures. In humans, it is deactivated by enzymatic hydrolysis to several carboxylic acid metabolites, whose urinary excretion half-lives are in a range of 5–7 hours. Worker exposure to the chemical can be monitored by measurement of the urinary metabolites, while severe overdosage may be confirmed by quantitation of cyfluthrin in blood or plasma.

Cyfluthrin is a skin and eye irritant in humans, but overall poisonings from pyrethroid chemicals are rare. In humans pyrethroids are rapidly broken down by the liver proteins. In addition pyrethroids are not absorbed into the bloodstream very well. Cyfluthrin may cause itching, burning, or stinging if it comes in contact with human skin which may last up to 24 hours. The onset of these symptoms can take 1 or 2 days to appear after initial exposure but may also occur at the time of the exposure. Sweating and/or sun exp exposure to sun/heat may exacerbate skin irritation.
