Q. How long will it take for this product to begin to work?

A. The product should begin to kill fleas within 24-48 hours but may take up to 72 hours to reach its full effectiveness.  

Q. What is the difference between this product and oral flea products?  

A. This product is applied to your pet topically and kills fleas through contact with the product on your pet’s skin, so fleas don’t have to bite to die.  With oral flea medications, fleas must bite your furry family member and be exposed to the medication in the pet before the fleas are killed.  

Q. How do these products spread over a pet’s body?  How long does this take?  

A. This product is topical only and is dispersed over your furry family member’s body by the natural oils on their skin and attaches to the hair follicle. This process can take up to 24 hours.  

Q. How does this product work?  

A. This product contains three active ingredients: imidacloprid which attacks the flea’s nervous system, paralyzing and ultimately killing them, permethrin, another ingredient that attacks the flea’s nervous system plus pyriproxyfen, an insect growth regulator (IGR) that prevents flea eggs and larvae from maturing into adults. This combination plays a crucial role in existing infestations because: you might only be aware of adult fleas which represent around 5% of a full infestation plus immature flea life stages (flea eggs, larvae and pupae) that exist in your environment make up the rest of the infestation are almost invisible to the naked eye.
