45 Best I can find
Verified Purchase

Although this product only keeps flies away for around an hour it is still far better than any other horse fly repellent I've bought - and I've bought a lot over the years!

Having tried many fly repellents, Phaser is without doubt the best, and having looked around Viovet can't be beaten on value and service

Sheep and goats

Amanda Young

  • VioVet customer since 2011
  • From: fife, United Kingdom

Can this be used on goats and sheep?

  • VioVet Staff

This product is only intended for use on horses, it may not be safe if used on a goat or sheep. We stock a wide variety of sheep fly repellants though on our website though.

Can you use this on human skin?


I’m looking for something to stop getting bitten to death by horse flies whilst mowing the lawn. Someone said don’t bother with regular insect repellent as it doesn’t work and to get fly spray for horses. Anyone had any experience with this?

If you can’t use it on human skin I wonder if spraying it on clothes would help and if so is the product damaging to fabrics?

  • VioVet Staff

This spray is only licensed for use on horses, we cannot advise whether it is safe for use on people. You should contact your local pharmacist for effective human safe fly repellant.

Use on dogs?


Could you tell me if this is suitable for use on medium sized dogs? Many thanks.

  • VioVet Staff

This product is not safe for use on dogs, it is intended for use on horses. If you would like advice on preventing flies with your dog then please get in touch at [email protected] so we can advise on appropriate products.

Fly repellent


Could this be put on something to repel the flys from my garden? If so what would you suggest I put it on? Would it be safe with cats around? Is the smell too horrible for us to be able to enjoy the garden if we use it? Many thanks

  • VioVet Staff

This product contains DEET and IR3535 oil. These both don't kill insects but work to repel them on objects they are applied to. DEET oil does have moderate toxicity to aquatic organisms so I do not recommend using this in the environment if you can. It is unlikely to be effective either as you would have to apply the oil to everything you want flies to be repelled from.

I recommend contacting your local garden center to find plant-friendly products that will repel flies from them. A fly trap may be more appropriate, such as those found in our Fly Trap Range.

Pregnant mares

Alana Macartney

Hi, is the power phaser fly spray safe to use on pregnant mares?

  • VioVet Staff

I have contacted Leovet and they have responded with the following:

'Usually the repellent will be sprayed on the fur and all ingredients
will adhere on the hair mostly. Therefore there should be no or just a
little contact to the skin.
The application of Power Phaser for
pregnant mares and foals is possible if the requirements and
precautions communicated on the label are satisfied.'

Louise Bang

  • VioVet Staff

Hi Louise,

Thank you for your query.

Please be advised that the ingredients in this product are not listed on the FEI prohibited substances list which makes it absolutely fine to be used when competing.

I hope this helps.

Power phaser fly protection

Carolyn Hague

does this product contain DEET?

  • VioVet Staff

Yes, it contains a high concentration of DEET.

15 May 2014 at 7:35pm



Is there citronella in it.

  • VioVet Staff

There is not citronella in this product. It relies much more modern, manufactured insect repellents, not "natural" compounds. It is generally very effective.
