open-in-new
<p>Cyfluthrin is a <a href="/facts/Pyrethroid/Lf1N0STQ">pyrethroid</a> <a href="/facts/Insecticide/1xYL3MSD">insecticide</a> and common household pesticide. It is a complex organic compound and the commercial product is sold as a mixture of <a href="/facts/Isomer/PXlvDVdg">isomers</a>. Like most pyrethroids (MoA 3a), it is highly toxic to fish and <a href="/facts/Invertebrates/3CyqCVnN">invertebrates</a>, but it is far less toxic to humans. It is generally supplied as a 10–25% liquid concentrate for commercial use and is diluted prior to spraying onto agricultural crops and outbuildings. </p>
