55 Effol Horse fly Blocker special
Verified Purchase

By on 10 August 2020

This product comes labelled as Effol Horse fly blocker special and not as the blocker plus. Also, It has only 3 pictures of flies it controls as opposed to the blocker plus picture that has 4 fly pictures. However it works very well and actually stops the files.

Such a good product. We live in Normandy and ride in mostly forests, the horseflies were becoming a problem, this product really works.

It is quite expensive but one of the most effective fly repellents I have used & as a professional groom I've tried a wide variety.

55 Wow

Brilliant stuff that actually keeps horse flies off my mare - not a single one landed on her. Make sure you follow instructions - you need to use quite a lot. Believe there is a product for riders too which I must get because they still bit me! Expensive but works.

Skin Reaction


Would this be ok for a horse with sensitive skin

  • VioVet Staff

This fly spray is fairly concentrated so has the potential for your horse to react to it. That said it is difficult to predict what an individual horse might react to. I would advise trying it on a small area of your horse first (avoiding anywhere tack would go). Once you are confident your horse isn't going to react you could use it to spray the whole horse. Alternatively you could try NETTEX Fly Repellent which is marketed as suitable for horses with sensitive skin.

Does it work for humans

Matt Spooner

will this keep horse files off humans

  • VioVet Staff

We cannot recommend this to be used on humans as it has not been shown to be safe for that use. The most effective products for people are those which contain a high percentage of DEET. A good example would be Boots Jungle Formula Maximum Strength, which contains 50% DEET as well as plant extracts. No flies or other bugs will go near you if you apply this! It is regarded as very safe to use too.
