Containing essential oils from six different sources, and some secret ingredients, this is a fly repellent that really works. Occasionally, a horse may be allergic to a particular essential oil, so a small area should always be tried first if you are using for the first time.
This is an extremely effective and long lasting fly repellent for horses and other animals.
It is a powerful, no mess, extra strength clear gel containing 15% Ethyl Butylacetylaminopropionate, better known as IR3535 to help repel many biting insects, including flies, midges and mosquitoes.
In extensive trials in 2012, it proved to be a very effective repellent, especially when compared to products based on Deet. It was both more effective and also, just as important, it lasted considerably longer. IR3535 is also considerably less toxic than Deet.
