Two classes of insect growth /development regulators have been registered for use as flea control products: juvenile hormone analogs (methoprene, pyriproxyfen) and chitin synthesis inhibitors (lufenuron). 1 These agents have no adulticidal effects but prevent the development or maturation of immature flea stages.

The spray may contain other insecticides (usually a pyrethrin) but it must contain an insect growth regulator to be most effective . One of the common names for methoprene is Precor. Insect Growth Regulators (IGRS) act by disrupting flea development from larvae to adults Non-biting larvae never develop into adults and eventually die.
