Thank you Blue,
What you just mentioned seems serious.
I am researching day and night for a solution to this nightmare.
As per the hint of Steph i ordered some products online.
And I will prepare tomorrow some home made recipies (
Home-made fly repellents for horses).
It's been a couple of days Cheena is having diarrhea in the morning, I think (and I hope) it's because of the night's chilli weather.
Now you opened my eyes to a possible serious problem.
I'm starting a new research about fly strike now.
I know eventually i will find a proper solution for those pests, I just hope it will be the soonest.
Thans once again.
George
