An indebted thank you to Boyce and The NRG Team for helping to stop our cheeky 8-month-old lab puppy from chewing the dangerous electrical cords around our home! We applied NRG Bitter Biter two weeks ago, and there have been no more mishaps since!

Having been in the horse industry for many years from competing, pleasure riding, breeding and everything in between there has always been a need for a product to prevent horses chewing, playing with, and generally doing damage to fences, rugs stable etc.
We have really enjoyed working with NRG, testing, sampling, and refining their fabulous new product ‘Bitter Biter’.
We have used the product in our hard wood round yard where we have always had trouble with horses chewing the rails. We painted several experimental coats many months ago before we were eventually happy with the results. Through a tough Melbourne winter, the horses are still reluctant to chew or lick the rails.
Having confidence in the results from the round yard, we also painted the product on various walls and doors in our new barn. The horses have not touched those areas.
We continue to use and recommend ‘Bitter Biter’.
The significant points of difference between this and other products are
1. Longevity
2. Ease of use
3. Invisible
4. No airborne fumes for the user

We have been using Bitter Biter for almost 2 months and continue to be very pleased with the results .
The product seems to be working very well on timber posts and rails , plastic troughs, as well as steel products . If given an appropriate time to dry, the product will work over a period of weeks without impacting the horse’s appetite or water intake.
It is a very good alternative and very simple to apply for any Team Member.

Bitter Biter has flipped my little woodpecker ponies mindset.
I use it on my posts outside and its lasted weeks, not just days!
It’s a perfect deterrent for those pesky chewers.
