Horses can be bad news when it comes to cribbing, chewing wood, eating seedlings & plants, or debarking established trees. There are various temporary horse repellent options on the market including DIY brews, hot sauces, essential oils, etc. For cribbing there are electric collars, chemicals, even surgery, etc. 

FATBANG is 12% beef-sheep fat emulsified into a spray-on liquid that is repulsive to horses.  Similarly, GREASEBANG is rendered animal fat in a grease form and could be more suitable for smearing onto timber stalls and timber where cribbing is apparent. Both GREASEBANG and FATBANG repel horses through odour, texture and taste. 

To repel horses just brush-on or spray the area to be protected. To prevent tree trunk debarking spray the bark liberally before the point of run-off. FATBANG is long lasting and rain-fast within 1 hour. It is a natural horse repellent without the use of nasty chemicals.
