Zodiac Premise 2000 Flea Spray kills adult and pre-adult fleas and ticks hidden in carpets, rugs, drapes, upholstery, pet bedding and floor cracks. It contains a unique combination of two insect control ingredients. Precor, an insect growth regulator, effectively breaks the flea life cycle for 7 months by preventing the flea’s development into the adult biting stage. The permethrin kills adult fleas, brown dog and American dog ticks.
