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 IGR targets fleas in the egg and larval stages of development. As a result, pre-adult fleas cannot produce new infestations of breeding, biting adults. Precor IGR prevents adult fleas from emerging for 7 months! Precor also provides excellent control of cigarette beetle populations.
Precor IGR is approved for tank mixing with other pesticides (such as Suspend SC, Demon WP) for existing infestations. Pour one ounce of Precor concentrate is mixed in one gallon of water and spray on baseboards, furniture, carpet, tile and other flooring. Precor is "water safe" for fabrics. Formulated to use alone or to be tank mixed with a pesticide labeled for indoor flea control.
