Pantry moths Sat, Jan 17, 2009 at 12:53 PM
Hi, Bugman! I just spent the day cleaning out my pantry, re-packaging food, and cleaning everything down.
I am having a problem with small tan moths that I haven’t been able to identify online. I see the moths most often at night, and they seem attracted to lights. The moths are about 1/2 inch long.
The closest match I can find is the angoumois moth. As you can see from the attached pic, they do have a fringe at the ends of their wings. However, the pics I’ve seen of angoumois moths show pointier wings. And my moths all have a pair of large brown spots midway on the wings.

Mediterranean Flour Moth???

Hi Erika,
Most Pantry Moths we receive are Indian Meal Moths, but we believe you have Mediterranean Flour Moths or Mill Moths, Anagasta kuehniella, or sometimes Ephestia kuehniella .  The PennState College of Agricultural Sciences Department of Entomology has fact sheet on the Mediterranean Flour Moth with drawings, and describes the moth as:  “a pale-gray color and from one-forth to one-half inch long, with a wingspread of slightly less than one inch. The wings are marked with two indistinct, black zigzag lines. The hindwings are a dirty          white. When at rest, the moth extends the forelegs which raises the head          and gives the body a sloping appearance. This posture is very distinctive          and is a more reliable character for identification than the wing markings         which may be rubbed off. “  There is also a drawing on the UK Stored Product Insects website.  The larger size of your specimen is a contributing factor to our hesitant identification, but we eagerly welcome a more expert opinion on this matter.  Though it doesn’t have a photo that resembles your moth, we found the very helpful Kendall Bioresearch Services Domestic Moth page.

Indian Meal Moth
I am having difficulty sending this. We just got power back after a week from the effects of Tropical storm (previously hurricane) Ike. I am writing today to hopefully help others with this nuisance. I searched your site (which I love) for information on the Carolina Praying Mantis we found and thought I’d look up this little booger too. Since you don’t have any photos, I thought I would include some for you. The eggs are almost impossible to see as they are camouflaged to look like the food they are laid in. The white caterpillar, AKA ‘worm’ is about 1/2″ in length.

The adult moth is much shorter at approx. 1/4 ” in length.

Indian Meal Moth

After the first infestation, in which my kids almost ate some of the ‘worms’ in their Cheerios UGH!! , I threw away all infested food and thoroughly washed out all cabinets and canned goods before putt ing them back. It seems that they are able to chew holes through plastic bags also, so I bought see-through canisters to put my dry goods in the last time. This worked for about a year or so. Imagine my mortification when I came across this last sight…… I bought Raisin Bran and after coming home from the store, it was placed in it’s canister. It sat for a while in the canister on the bottom of the cabinet and recently found at least 50 or more ‘worms with their silken threads all in the cereal!!! P I always check my bags for holes especially if I find, for example, a small amount of brownie mix finding it’s way out of the bag before I open it. I’ve heard these are quite common and most people, disgustingly enough, inadvertently eat the eggs in their food without realizing it!! I know y’all don’t endorse extermination, but I draw the line when they are in my food! ) Hopefully the files are small enough not to block your e-mail and big enough for everyone to see. Pl ease let me know if you have any problems. Thanks! I’m off for a good scrubbing again!

Indian Meal Moth Infestation

Dear Disgusted,
First off, we sympathize with your loss of power. Mom, in a suburb of Yourngstown’s east side, was without power for twenty hours. Thanks for this wonderful letter and documentation. We do have images of Indian Meal Moths on our Pantry Pest page, but we need to check to see if they got lost in our site migration. Keeping grain products in tightly sealed cannisters is not always a solution, as food may be infested at the factory, at the warehouse, or on the shelf in the market. Spring cleaning of items in the pantry on a yearly basis will help reduce the risk of infestations. Also be mindful that nuts and spices are not exempt from beetle and moth infestation.
