This week on the Ask A Vet Question Facebook Page, a fan asked me if I had heard of a shortage of Advantage flea control. Apparently she has tried to order it from multiple places with no success. My own staff recently tried to order Advantage from our supplier and it is on backorder.
On the Bayer Advantage website, there is no mention of an Advantage recall or shortage. However, I did notice that under the “products” section Advantage was not listed. Instead, the focus was on Bayer’s new product Advantage II.
Advantage II contains the same ingredient as Advantage – Imidacoprid. But, it also contains an additional ingredient called pyriproxyfen. Pyriproxyfen is an insect growth regulator. The addition of this drug to Advantage, makes Advantage II able to control all life stages of fleas and not just the adults as before.
It looks like Bayer is phasing out Advantage and instead, selling the new Advantage II. So if you are trying to buy “regular” Advantage, you likely will not be able to find it.
Have you used the new topical flea product Advantage II? If so, I would love for you to leave a comment below. Your comments will help people who are searching for similar information.
