I found a whole bunch of tiny little bugs on the feed bins,which I keep away from the animals in a seperate shed. they're tiny and whitish beige,,no wings,,and I only find them on the bins and not actually in the feed..they seem to like the crevaces on the bins and hide out in there. does anyone know what these would be? and how I got them? they remind me of lice,,but aren't near the animals...I would like to know what I can do to get rid of them..thanks
