Creepy things in my layers pellets?

I keep my layers pellets and corn in two separate dustbins but today I found what I think may be Weevils in those bins.  Is it all right to just leave them to the chickens to eat them?

I would want to know how they ended up in the bins - is the food stale and out of date? Fresh feed and clean bins shouldn't have any creepy crawlies in at all.
I don't think I would be happy feeding it to my hens.

They may not be "weevils" but another beetle larvae (it doesn't really matter to you as you just want rid). It is very common to get the eggs/larvae in pet/animal foods. They're not a danger in themselves, but are destroying the nutritional value of the food. To have weevils in two separate bins suggests a problem. The usual problem is that bins are not emptied, but are "topped-up" so the infestation at the bottom has a chance to thrive. A difficult one and I'm just as guilty as nobody wants to run out of food and how do you move binned food around?
The only answer is to empty the bins, clean and put in fresh food then use all before putting in new food. I'd suggest just using up the food; the chooks will enjoy the larvae  which are the sorts of things they seek when free-ranging and they won't come to any harm. You could have a new bag of food kept separate and mix in a little if you're worried about nutrients, but I wouldn't worry.
BTW you may be amazed at the amount of insect debris you consume in your daily food
