The plastic containers won't do it. Heavy duty hard plastic with screw tight lids might work, and the same for glass. A friend of mine had a major pantry infestation and we found the larvae in her peanut butter!!!! With the lid on tight.

Place your teas in a zip lock bag and observe for signs of the adults or larvae. Personally, I think that tea would not be safe.

Clean out any pet food, bird seed, spices, even potpourri and craft supplies, pine cones, etc. Do a major cleaning to get rid of the little cocoons that you will find in the nooks and crannies of the house...and not just in the kitchen! I found an infestation in my bedroom closet, where I kept a couple of (closed and not used) bags of that fancy potpourri that had been given me. I had been planning on 're-gifting', lol!!!

I've heard good things about pantry pest traps (non chemical), and suggest you investigate them.

Once you get rid of the adults, freeze food items for a few days before introducing them back into the pantry. And storage in the 'fridge is a good idea, too.

You won't need to refrigerate the bread. (And in fact, it would stale even faster there than if stored the pantry.) But related things such as flour, including bread mixes, and crackers are at risk.

thanx for the all the feedback.
-rhizo, spices, really? man, we have *so* many delicious spices! is there a certain spice that you've found them in? or do you think they're all at risk? so does that include dried herbs?
-jean, you're sure about the bread? why would it be safe? it just makes me so nervous. i know they arent harmful, but the thought of eating little insect eggs really makes my skin crawl.
thanks again, both of you
