Fly spray recipes

[spotty_pony]

Can anyone give me an easy one I can make with the correct quantities?

I've just ordered some citronella, tea tree and lavender oils to include. Hoping to save £££s on fly spray this year and make my own!

I've tried quite a few essential oil concoctions in the past. They smell lovely and work for an hour or so. Alas, the best recipe for fly spray I have come across is 1 x online store, 1 x Paypal and 1 x Tritec ?

Doterra Lemon Eucalyptus essential oil is very effective - diluted with water - 20 drops in a standard cleaning spray bottle ?
