First of all, my wife is making me write this! This spring we're doing battle with moths in our cupboards. They've infested cereals, grains, and whatever else they can sink their little mothy fangs into. This year's infestation seems worse than any before; this is also the first spring since I started storing massive (too massive, but that's a tale for another time, and I'd guess you've all told it yourselves) stores of green coffee beans in the cupboard. I maintain that green beans, in all their seedy imperviousness, do not offer safe harbor to the moth hordes. But my wife wonders if any of you have had any experience with lepidopterous beans? Gratefully, Roger Sierra Madre, California
Living in Hawaii my green beans seem rather impervious to everything except rodents.
I don't know about moths in coffee, but I know that in general with moths, your strongest weapon is your freezer. Freezing temperatures kill the eggs/larvae. So cycle all your pantry goods through the freezer, as much as you can fit at a time, and leave them for at least 12 hours. Then cycle all your wool and silk clothing and other textiles (including yarn if you have a knitter in the house) through the freezer as well. (Cotton, linen, and synthetics are not as much of a problem.) This can take a long time with a small freezer; a separate freezer chest can make it go much faster. Getting back to coffee -- my understanding was that caffeine is a natural pesticide, which is why it evolved in the plants in the first place. But I don't have any first-hand knowledge on the subject.

He suggested discarding already purchased grains and putting all new grains, birdseed, and kibble in plastic containers (or at least heavy ziploc bags sealed with tape). I would think green coffee beans are too dense for grain moth larvae to try to eat.

Do you store dog biscuits in the cupboard too? I had a bad problem with moths that were hatching from the Feeders Supply bagged dog biscuits. I've never had a problem with coffee moths. ********************* Ed Needham® "to absurdity and beyond!"http://www.homeroaster.com(include [FRIEND] in subject line to get through my SPAM filters) *********************
I have one memory of Tom mentioning an infested bag of beans (IIRC) - that went STRAIGHT into the dumpster. Aside from that, I have never heard of moths in coffee. I have had moths in cocoa, and finally eradicated them, but during that time they never had an interest in the coffee.

Moths in coffee, not likely. Moths in flour, grains, cereal? You bethcha! Wifey has targeted the wrong guy. Dan M
I bought a well used Trosser grinder off Ebay and when I took it apart to clean it I found it had many dead grain moths up in the grind mechanism and clinging to the spring. The grinder appeared to have been retired from use and not cleaned. The moths would have been feeding on the remains of the ground coffee. Grain moths have become coffee snobs!

Pat, Were the remains in the Trosser clearly from coffee? I'm wondering whether the Trosser might have been used to grind something other than coffee. I bought a coffee mill on eBay that was all gummed up with the remains of nuts. Brian On 6/6/07, Pat Murray wrote: <Snip>
We had moths come in on a Zambia coffee once about 6 years ago, in ohio. they were on the bag, the burlap, and we noticed them when we unloaded it from the truck that was delivering it. needless to say, we didnt even bring it into the shop. since we were sending the coffee back to the port anyway, i decided to open it up and see if any moths were inside the coffee. they weren't, only on the bag. so i imagine moths might like the cloth or jute, but i don't think the coffee is food for them, or hospitable for breeding. <Snip> -- "Great coffee comes from tiny roasters" Sweet Maria's Home Coffee Roasting - Tom & Maria http://www.sweetmarias.com Thompson Owen george_at_sweetmarias.com Sweet Maria's Coffee - 1115 21st Street, Oakland, CA 94607 - USA phone/fax: 888 876 5917 - tom_at_sweetmarias.com
Good point Brian, There is really no way I can be sure that the grinder did not grind more than coffee. It was really funky, I had to use denatured alcohol to dissolve all the crud. Pat On 6/6/07, Brian Kamnetz wrote: <Snip>

<Snip> Roger, I normally get them every year down here in Orange County, CA, but this year I haven't seen very many. I guess theyall moved up to Sierra Madre. Some years I have to seal flour, corn meal, and other items in airtight bags to keepthe moths out. What works is a product called Pantry Pest. It's a cardboard triangle with sticky goo on the inside and a pheromonereleaser. You can't stop the initial infestation (that comes from outside) but once they're big enough to fly it snags thebugs before they can reproduce. I buy it either at a gardening store or at Long's Drugs. HTH Frank Parth
