The Bayer Animal Health pharmaceutical company released new versions of their Advantage® and K9 Advantix® ‘spot on’ flea products.
According to Bayer, these new formulas will kill fleas at all life stages and prevent flea infestation in the home.
The older formulations of these products contained only an adulticidal. The new versions will have larvicidal and ovicidal properties with the addition of the chemical pyriproxyfen, an insect growth regulator (IGR) that prevents the development of flea eggs and kills flea larvae as well.
Pyriproxyfen targets the hormone pathways of insects, but does not affect mammals, according to Bayer.
According to Peter Ryan, vice president and head of the company’s Companion Animal Business Unit:
“Adding pyriproxyfen to the original formulations of Advantage® Topical Solution and K9 Advantix® gives an added layer of protection to our customers’ pets and their pets’ surroundings. It interrupts the flea life cycle at multiple stages, and prevents reinfestation.”
