250 ml of Avon Skin so Soft and fresh - 500 ml bath oil. This can be halved if midges too bad. I am presently using one third of a bottle which works well.
1 teaspoon of citronella oil - can go up 1 1/2 for bad midges.
1 teaspoon of eucalyptus oil
1 teaspoon of lavender oil
1 teaspoon of tea tree oil
1 teaspoon cedarwood oil
Put into a 1 litre spray bottle. Top up to make 1 litre with either water or cold tea. Shake well before spraying and give a quick shake after every few squirts to make sure the oil is mixed with the water.
Spray on twice a day using enough to leave a fine mist on the coat. Ok for round sensitive areas.
I have used this on people as well as horses, but please do a patch test first in case your horse reacts to any of the above ingredients.
Cost works out about £3.00 a litre - not as cheap as some receipes but this does work well and smells nice.
Just replied to similar post on new lounge, this works a treat, everyone has noticed how many more flies their horses have to mine, been giving out instructions left and right, wish I had shares in avon!! great for us humans too
