According to the Merck Index, fluvalinate has the empirical formula:

C  H  ClF N O
 26 22   3 2 3

So yes, it contains a small amount of chlorine and fluorine.  The
structural formula is a bit beyond my ASCII art abilities, but
it is essentially two benzene rings connected by a rather messy
collection of C,H,O, and N, with one chlorine and a CF3 group hung
off of one of the rings.
