Talstar P Professional Insecticide can be mixed with insect growth regulators such as Precor IGR. Be aware though that Precor is only labeled for use indoors but Talstar cannot be used as a broadcast across surfaces inside the home such as carpets (it is only for cracks and crevices) so if you are treating for fleas it is not the best option as an insecticide. Instead you should use something like Conquer or Onslaught.
