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.
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.
