I have never paid for proper flyspray in my life..This recipe with get you nearly two litres of repellant.
1.5 ltrs of VERY strong cold tea,
10ml of Citronella oil,
500ml of malt vinegar,
Some people put a dash of washing up liquid in but i dont.
Chuck it all in a washed out 2ltr coke bottle.Then put in into a garden mister spray bottle.If you have a grey like me it is best to put it on a fine mist setting as it can stain the coat.Please make sure you label the bottle as to what it is...My hubby said the 'coke' tasted funny.
1 bottle cider vinegar
same amount of water
1/3 bottle tea tree oil
mix up in spray bottle very cheap and works great
Iused to use shop bought fly spray as well as fly sheet on my girly and she used to come in with odd bites, started using this july last year and she can go out without fly sheet and rarley see any bites on her.
