I let a buddy house a cow at my place for a couple weeks. She brought lice. All my cows are now scratching. I gave them all a dose of Ultra Boss (5% permethrin and 5% piperonyl butoxide). I didn't repeat the second dose 2 weeks later because the label says, " Season long lice control with one application." My cows are still scratching. Any advice? I want a complete kill. Ear tags, injectables, I was told my a local show guy to use a blow torch ? I currently have Dectomax Pour On, Ultra Boss, and Cylence. Thanks. And my buddies cow is long gone.
