Precor Insect Growth Regulator (IGR)

Concentrated Methoprene Products

Precor (a.i. Methoprene 1.0 %): Odorless IGR concentrate which keeps immature fleas from growing into reproducing adults - thus breaking their life cycle.  Used alone, Precor will prevent indoor flea infestations for three months or more.  Precor also provides excellent control of cigarette beetle populations.
Approved for tank mixing with pesticides (Suspend SC, Dragnet SFR) for existing infestations.  One ounce of Precor concentrate is mixed in one gallon of water and sprayed on baseboards, furniture, carpet, tile and other flooring and is "water safe" for fabrics.  Formulated to use alone or to be tank mixed with a pesticide labeled for indoor flea control.  (Methoprene is the "plus" in Frontline Plus for Dogs and Frontline Plus for Cats.)
Cannot be shipped to AK, HI

Methoprene concentrates are available in Precor pints and in Precor Box, a container of 10 pre-measured vials.  For those who do not like to use concentrated materials, Precor 2000 Aerosol is also available.
