Clear, stable, efficacious, aqueous microemulsions of a pyrethroid insecticide, optionally with another agriculturally active ingredient, are provided herein. The aqueous microemulsions are obtained by providing an inert matrix composition containing a defined mixture of nonionic surfactants, optionally including an anionic surfactant, mixing with a pyrethroid to form a microemulsion concentrate, and diluting with water. Preferably, the aqueous microemulsion includes an N-alkyl (C1-C4) pyrrolidone therein as a cosolvent in the microemulsion system.
