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

Certifect also prevents the 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 re-infestation or if the pet has fleas which may cause flea allergy dermatitis, a once monthly application may be needed.
