Directions For Use

It is a violation of federal law to use this product in a manner inconsistent with its labeling. Read entire label and enclosed directions before each use. Follow all directions and precautionary statements carefully. Do not allow children to apply product. Use on dogs ONLY. Do not use on cats, rabbits, or other animals. Do not apply more than once per month.

Frequency Of Application

A monthly application of CERTIFECT® kills all stages of ticks, completely breaks the flea life cycle and controls chewing lice infestations.

CERTIFECT® detaches ticks when applied to a dog with a pre-existing infestation. Do not apply more than once a month.

Research demonstrates that CERTIFECT® kills adult fleas (Ctenocephalides felis and Ct. canis), flea eggs, and flea larvae for up to three months. CERTIFECT® also prevents development of all flea stages for up to three months. Although CERTIFECT® can control fleas for up to three months, if there is a high risk of reinfestation or if the pet has fleas which may cause flea allergy dermatitis, a once monthly application may be needed.

CERTIFECT® remains effective even after bathing, water immersion, or exposure to sunlight.
