Norbrook Laboratories has launched Fiproclear Combo, a new spot on for the control and prevention of fleas, ticks and biting lice.

Fiproclear Combo, which contains fipronil and S-methoprene, is licensed for use on cats and dogs and can also be used to treat and prevent fleas and ticks on ferrets.

Norbrook says the new product provides effective protection from new flea infestations for up to eight weeks on dogs and four weeks on cats, while protecting against certain ticks for up to four weeks on dogs, and two weeks on cats.

Monica Whistler, Norbrook Marketing Product Manager, said: "With its triple-action approach, Fiproclear Combo kills adult fleas, ticks and biting lice. The addition of S-methoprene to the already-trusted ingredient fipronil, breaks the flea life cycle in the home by ensuring that any eggs laid by the fleas, which have come into contact with the product are infertile, and by preventing development of flea larvae within a pet’s surroundings.

"Adult fleas on pets are killed within 24 hours whilst newly arrived ticks are killed within 48 hours of attachment – before the main risk period of disease transfer. Ticks rank second only to mosquitoes as insects that spread infectious diseases to both pets and people1; the most common of which is Lyme disease."

Norbrook highlights research which showed almost a third of cats suffered from ectoparasites2, while around one in every three dogs are affected by ticks3, and that many traditional treatments do not help break the flea life cycle in the home.

Monica added: "Typically, by the time an owner notices a flea problem, an infestation has already been present for up to two months. At that point the visible adult fleas on the pet are only part of the problem, with 95% of the parasites already living in the home itself as eggs, larvae and pupae."
