I keep my horse on a dairy farm and this by far is the best product around, it may not last 14 days but I apply every other day and it still works out about the same price as any other spray, you may get less usage on a straight livery yard as less manure, the way that I see it is that this works wether it last 14 days or 1 the relief on your horses face when they are not covered or irritated by flies is definitely worth the expense.

Love this product and is the only spray I’ve ever used that actually leaves her fly free.....she had fly worry last year because she was Plagued so badly with flies and I was unable to catch her for three weeks until it prevent this happening again and seeing she was starting to toss her head around and not want food and beginning to not let me catch her I bought this on a recommendation from a friend and it has worked.....she’s not been bothered by a fly since and is happy and fly worry free......can’t recommend this enough

Instructions say do not sparay directly on horses?

Linda Wells

  • From: Lincolnshire, United Kingdom

instructions say dont spray directly on horses but judging by reviews people have not read this ? Is it a fly spray for horses?

  • VioVet Staff

Hi Linda,

This product should not be applied directly to horses. It is a spray for stables and lorries to kill flies inside that would attack your horse.

Hope this helps,
