Only 5% of a flea population is adult fleas on a pet and targeted by shampoo and flea treatment. I recommend using a long acting product such as bravecto (3mths) or seresto collar (8mobtgs) and maintain protection for at least 18months to target fleas as they hatch. An insecticidal household spray or professional fumigators by pest control is vital to kill the eggs and larvae as well as disposing of bedding etc
