If you have access to a bay laurel tree, you can use the leaves (fresh or dried) to repel those little moths that get into your cereal and leave weevils behind. (My bug terminology might be bad, but the bay leaves repel them whatever they are.) I put my containers of breadcrumbs and such inside plastic bags with the bay leaves and haven't had nearly the trouble I've had in the past.
I have a tree that could use thinning if you're in So Cal.
Ha! Wish I had known this a while back, we called them flour bugs, and there we were, with plenty of Bay leaves on hand! (Can't make soup without bay leaves and dill.)
