There are basically two types of deer repellents that are worth considering. The rest are either largely ineffective, or just ridiculous! Repellents containing animal proteins or slaughterhouse waste are proven to be the most effective - and that's backed by field research.

BANGBANG IS EMULSIFIED BLOOD + EGG PROTEIN + FISH + FAT and is supplied as a 1L concentrate that makes 10L final spray. 

For RESIDENTIAL users FATBANG comes as a 4L concentrate that makes up 12L+ final spray.
