Hi! Had a question about a product by Durvet called Permetherin 10%. Has anyone used this product before? If so, what is the best way to use it for ticks and is it effective?
Thanks!

works better as a dip. you have to mix it very strong if you are spraying it. you can get the purple python ear tags for cows and put it on the dogs collar. it works for fleas and ticks.
