SHAWNEE, Kan., Jan. 31, 2011 /PRNewswire/ — Bayer Animal Health
announced this month at the North American Veterinary Conference,
the availability of its new products: Advantage® II for
cats and dogs, and K9 Advantix® II for dogs. These
products combine the adulticidal properties of the original
formulations of Advantage® Topical Solution and K9
Advantix®, with the insect growth regulator (IGR) pyriproxyfen,
which inhibits the development of flea eggs and kills flea larvae.
As a result, Advantage® II and K9 Advantix® II kill
all flea life stages and prevent fleas on a treated dog from

surroundings. It interrupts the flea life cycle at multiple
stages, and prevents reinfestation,” said Peter Ryan, Vice

Imidacloprid quickly paralyzes a flea’s mouthparts and kills
fleas through contact, so fleas don’t have to bite your pet to die.
By protecting pets from fleas, imidacloprid has been shown to
reduce the incidence of certain conditions including flea al
