I don't really see a way to edit the post, so here goes,
I've been looking around for hours on this stuff and it seems fairly new so there aren't many reviews / stories on this stuff.
But from a preliminary analysis it seems like it has the same active ingredients as bio spot defense spot on
Which everyone should know is no good and harmful, from what i've been reading. MSDS: BIO SPOT DEFENSE SPOT ON FLEA & TICK CONTROL FOR DOGS
Here's a great page for comparing flea & tick products: Dog Fleas: Compare Flea Medications and Other Flea Control Products
From the petco page, the bio spot's ingredients are:
Active Ingredients: Etofenprox (CAS # 80844-07-1) 30.0%, (S)-methoprene (CAS # 65733-16-6) 3.6%, Piperonyl butoxide (CAS # 51-03-6)* 5.0%. Other Ingredients: 61.4%. *Equivalent to minimum 4.00% butylcarbityl (6-propylpiperonyl ether) and 1.00% related compounds.
which seems exactly the same as the costco stuff, even in the same %'s.
At this time of posting I was only able to find a few sites talking about this kind of stuff: http://forum.greytalk.com/index.php/...k-form-costco/ Kirkland flea & tick vs frontline? - The DIS Discussion Forums - DISboards.com
also been reading a lot of bad stuff on bio spot defense spot on
So i haven't used it, but if anyone else is looking to use it, i would advise against it, b/c it seems like a rebrand of biospot defense spot on. Even looks like the exact same applicator. biospot = no good. But of course I've never used it, so if you say im stupid that's ur opinion. But my dogs health is much too important to risk for saving a few bucks on some sketchy stuff.
anyways, if you want some interesting biospot stuff check this out: Dangerous Pet Products? - YouTube
