I'm no expert, but if someone would post a picture of the bugs, I'll take a jab at it (or have my exterminator look at the next time he's around).

@90mcg112: lol I ate a bowl of Raisin Bran one morning at my in-laws' house and when I was nearly done, I noticed there were little brown beetles swimming/crawling around in the bran mush... Not just a few, but 40-50. There wasn't much left at this point, so I would imagine I ate hundreds if not thousands. I was fine though, just mentally bruised (I still can't eat Raisin Bran).

The ones you are describing sounds like weevils. They're usually in grains. I ended up with some from a bag of rice I bought at the grocery store. Luckily, they're pretty easy to get rid of... you just throw away any open grains (rice, flour, cereal, etc) where you find them.

I went back to the same grocery store about 2 weeks later and on a whim checked the rice aisle. Yep, just about every bag had weevils in 'em. I quietly got the manager and showed him. He was pulling every bag as I left.

@meems212: bay leaf? never heard of this. can you explain? is it an old timey thing or is there a science or just a lucky happenstance or what?

@moosezilla: I had forgotten where I found the info regarding Bay leaves, so I did a little digging and this is what I found so far, hope this helps:
This site has info on quite a few bugs and "natural" ways to repel them, scroll down for Bay leaves: http://eartheasy.com/live_natpest_control.htm

This one also has info on Bay leaves:http://tlc.howstuffworks.com/home/herbs-deter-flies-naturally.htm

This last one gives arguments for both sides, yes it works and don't work and lets the reader decide: http://www.everythingprepared.com/HomeFoodStorage/FoodStorageInsectControl.html

@capguncowboy: Ugh, nasty. Well, that settles it, yogurt for breakfast it is!

The weevils being discussed here show up in all sorts of pasta and grain products, and as far as I can ascertain they're present when the product is packaged. (Unless they've figure out a way to squeeze into cellophane bags and tightly glued shut cardboard boxes.) They're not related to the cleanliness of your home, and fortunately they don't seem to migrate to other foods. I've had them perhaps 10 times in 40+ years of keeping my own kitchen; for a while I tried keeping all pasta and grain products in Tupperware, but that was a lot of hassle and I gave up on it.

The real annoyance for me is when I reach for the pasta (always mid-recipe) and discover not only is it infested but it's also the only such item in the house. Grrr.

The weevil eggs are already in the grains. We have all eaten countless millions of weevil eggs in out lives and never noticed. If you store grains and pasta products where they get sunlight, the eggs will never hatch and you will never see them. That's why a lot of the counter jars for storing cereal, pasta, flour and the like are clear. Put them in a dark pantry and the weevils will hatch and make the food unpalatable.
