weevils in the feed bin

Probably from a hygiene point of view, bin them.  Can't help thinking the hens would just view little black weevils as an added bonus though 

 its the warm weather
we lived in cyprus for many years and had to check our flour before we used it

Thanks folks    This forum is great!  It looks like I will be emptying the feed bins, cleaning them out and refilling them tomorrow 
I like the idea of adding DE to the feed as a prevention ,ANHBUC.

Here's an interesting article from McGill University in Quebec on just this subject:

Or if you want to get really serious  you could read the Proceedings of the Eighth International Working Conference of Stored-Products Protection, York, UK, July 2002.
