If my flour is dated 08.2015

And the yeast says BB 30.09.2016, will my bread be toxic?

Or look anything like bread?

The tiny weevils I have seen in flour are too small to be sieved out.

I didn’t realise weevils were already in there, I thought because I had put it in a container it was OK. I will inspect very closely in future

Sieve it. If nothing's moving, use it.
