I have used Pig Oil and Sulphur for many years as my native horse suffers from feather mites. It has always been supplied in plastic containers and is messy to apply unless decanted into a spray. This product is clean, hygienic and portable.
I've started using this instead of some of the more expensive stuff I had and it actually works better as a detangler and also using on feet to protect from the mud
Its saving me money and doing a great job
