What does ivermectin treat?
It is predominantly considered a very broad spectrum wormer, but it also kills mites, lice and many other biting bugs.
I use pour-on, which does not mix well in water. For that you need injectible. Go to the Emergency/Health section and do a search on ivermectin and you should be able to find the dose.
How often do you treat? Have alot of wild birds around last thing i need or want is for them to transfer bugs to my girls...
