That would probably work. I use the Dry Oil Body Spray, but not sure if they still make it. (Mum is an Avon lady and had loads of the stuff so haven't bought any for ages)
I thought it had to be the blue bottle stuff.Found it I think because when you click on info for the body oil it says 'customer also bought 'and the dry spray is on there ,click on that and hey presto
Skin so soft , soft and fresh dry oil body spray or soft and fresh bath oil are supposed to be good for horses with sweetitch to repel the midges think you can just spray on or add to homemade fly spray with citronella, lavender, teatree oil and cold tea or water.
Anything is worth a go
Try this one - along with cold tea, 5 caps of dettol, citronella oil, lavender oil, cedar oil, tea tree oil and one i have forgotten - it really does work and smells lovely!!
.... and Eucalyptus.
I use the skin so soft and fresh bath oil 250ml add other stuff and top up to a litre, smells good, its bluey green (the bottle that is). It used to be the woodland one but they discontinued that one.
