Coopers Horse Fly Repellent Plus

  • 600ml Bottle £36.49

Effective and ready to use, Coopers Fly Repellent Plus is an economical and powerful fly repellent and topical insecticide containing the active ingredient Permethrin at 1.05% w/v concentration and Citronellol 2% w/v concentration. AVM-GSL

A white silicon based emulsion containing a fly repellent and a topical insecticide in ready to use form. Contains permethrin (technical) (25:75) 1.05% w/v and citronellol 2% w/v.

As a ready-to-use, topical application to repel and kill biting and other flies on horses; as an aid in the control of sweet itch, a condition believed to be caused by the midge Culicoides pulicaris; for the treatment and control of infestations of the biting louse, Damalinia equi. Also shines horses` coats.

Apply shortly before working the horse or when flies are troublesome, at the following rate:

  • Up to 300 kg bodyweight: 100 ml
  • 300 to 500 kg bodyweight: 150 ml
  • Over 500 kg bodyweight: Up to 200 ml

No dilution is necessary.

If the horse is to be groomed, the product should not be applied until after this has been completed.

Shake thoroughly before use.

Pour the product onto the sponge cloth and spread lightly over the horse`s head, neck, body and legs measuring the dose volume against the calibrations on the 600 ml container.

Fly control
Apply shortly before working the horse or when flies are troublesome.

Where flies appear to be troublesome only around the horse`s head and neck a reduced amount may be applied to these parts alone.

Repeat every other day or as necessary.

A treatment will normally give two to four days relief, but longer or shorter protection may occur depending on climatic conditions, the prevailing fly species and the intensity of fly worry.

Louse control
A single application of Coopers Fly Repellent Plus will usually eliminate adult populations of the biting louse Damalinia equi, and viable eggs for up to 3 months. However as this protection is not absolute, it is advisable to repeat treatment after an interval of 14 days. Ensure that the whole body is treated including the head and tail.

Do not use with other topically applied products.
Avoid application into the horse`s eyes and nostrils or into cuts and abrasions. Do not use on horses intended for human consumption.

For external use only.

A small proportion of horses may exhibit a skin reaction following application of the product. The reaction is normally mild and transient resembling nettle rash and usually resolves without the need for any treatment. Application to a small area on the side of the neck before the first use should determine within 24 hours whether such a reaction is likely.

Protection of operators
Avoid prolonged contact with the skin. Impervious gloves should be worn when applying this product. Wash hands and exposed skin before meals or smoking, and after work. In cases of contact with eyes, rinse immediately with plenty of water and seek medical advice.

Protection of livestock, wildlife and others
Dangerous to fish. Do not contaminate ponds, waterways or ditches with the product or used containers.

Wash out used sponges and keep in a safe place until they are to be disposed of with the empty container(s).

Wash out empty containers thoroughly together with the sponges supplied and dispose of safely by burying in soil or by placing in a refuse bin.

Pharmaceutical precautions: Store in the original container, in a cool place away from food, drink and animal feeding stuffs.

Package quantities: 600 ml.

Lice infestation

26th Jun 2016
Jenni Steel
  • VioVet Customer Since: June 2016
  • From: Northumberland (GB-NBL), United Kingdom

My TB horse has been badly infested with lice. The vet perscribed Deosect which I use. He has had the lice for 4 months and I'm still struggling to get to the bottom of it. We have clipped, hogged his mane and one third of his dock. I have also been trying oil and creams. Which are helping too. A friend suggested the Coopers Horse Fly treatment.

I am concerned that it may not mix well with the Deosect which is due to be applied this coming Saturday. Please can you help. Many thanks Ann Steel

Deosect is usually much more effective than fly repellents. I would not apply both products at the same time. It might be safe to do so, but some sort of adverse interaction might be possible. Horses are particularly prone to lice when they are not in perfect health otherwise. A robust horse can have one or two lice but their immune system seems to be able to keep them at bay and you would never know they were there. If your horse is not in contact with others which are also badly infested, then one would have to wonder why his immune system is not doing better. I presume there is not chance of him having "Cushing's syndrome" or some other condition. Your vet might need to check this sort of thing out.

Otherwise it is perhaps possible that the lice are in some way resistant to Deosect, though I have not heard of that happening. Your vet should be able to tell you if they are biting or chewing lice. The biting lice can be treated by injection so that coiuld help. Otherwise an alternative treatment to Deosect could be worth trying and the Coopers product is worth a go, but I would allow 7 days between using the two products.
