Gentrol Point Source is not labeled for fleas and would not be effective to eliminate juvenile fleas.
Gentrol IGR Concentrate would be recommended for adding an IGR to the tank mix along with an insecticide labeled for fleas and broadcast surface spray application indoors to carpets, rugs, pet bedding, etc. IGR's alone do not kill insects, they only stop the growth cycle.
Gentrol IGR Concentrate is mixed at 1 fl oz per gallon of water along with an approved liquid insecticide concentrate labeled for fleas.
Another option would be to use
PT Alpine Flea and Bed Bug Aerosol that contains the insecticide and IGR in one convenient aerosol to treat carpets, rugs, pet bedding, etc. Please view the
product label for more information.
