An insecticidal composition comprising stabilized pyrethrins or pyrethroids is provided. Such composition includes stabilizing effective amount of N,N-dialkyl fatty acid amide solvents and certain ultraviolet-light absorbers. In such composition, the pyrethrins or pyrethroid can retain their insecticidal activity for an acceptably long period of time. Therefore, an advantage of this invention is to provide a topical pyrethrins or pyrethroid based insecticide which can remain effective in light over a long time period. Another advantage of this invention is to provide a stabilized topical pyrethrins or pyrethroid insecticide insecticidal formulation containing a high concentration of the active pyrethrins or pyrethroid ingredient to minimize the volume of formulation required.
