what is this? plz help

We weren’t sure exactly what type of Pantry Beetle, so we asked Eric Eaton who responded: “Ah, well, these are Anobiidae beetles of some kind, most likely the drugstore beetle or the cigarette beetle. Was it smoking? Just kidding:-) In any event, it is a stored product pest in that family. Thanks for sharing.

bug info
We are having this bug on our carpet for a while. Apparently it’s harmless, but since I have a 6-month-old baby, I’d like to check what it is. I’ve looked at several bug pictures, but could not find it. We also find them sometimes on our bathtub. We live in Boston, MA. It is the size of a small ant, very small. To kill it, I crush it and it sounds like killing a pregnant dog’s flea, it cracks. I’ve put a couple in a completely closed jar a few days ago, and they are still alive. I’m sending some pictures I took. I’d appreciate any kind of information you could provide me.
Thanks a lot

Dear Melina
We were not sure exactly what species of beetle you had, though we suspected some type of Pantry Beetle. We contacted a true beetle expert, Eric Eaton who gave us the following reply:
“Some pretty clear images of pretty tiny beetles! They are spider beetles, Mezium americanum. It is a stored product pest, so best to inspect the pantry to find the source of the infestation. This should also include examination of pet food, taxidermy mounts, insect collections, the spice rack….Aside from adding some inadvertent protein to one’s diet, though, they are of no real consequence even if you don’t ever find them. Aside, we’d love to have these images submitted to Not even sure this family is represented yet.
Ed. Note: We put Eric in contact with Melina and hopefully she will give permission to post the images on

what is this bug?
1/4" in length. many legs on each side. somewhat hairy. has a wormlike head that wiggles around, the back end almost looks like wings creeping out from under a jacket. the jacket is light oolored belt around the midsection and the ends are darker. the tummy of the bug is all light colored. they had no visible antenna or tail (through a magnifying glass)…… 4 of these were on one sons wall in his bedroom. one more was sighted in an upstairs bedroom. they are very slow moving, in a slow wiggle sideways. when dropped in the carpet, they burrow down into it. help. thanks.

Hi Jean,
You have a Carpet Beetle Larva, one of the Dermestid Beetles which eat wool and other natural fibers as well as doing major damage to museum collections.

Help Me Figure Out What This Is…
My house has recently had an infestation of a bug that seems to really be a fan of grain. We’ve found it inside our sealed cereal boxes and also in packets of oatmeal. After putting all of our food in sealed containers the contagion seems to have died down, but now I’m finding some throughout our house. I took a number of digital pictures but this is the only one that came out pretty well. The bug resembles a very tiny ant except it obviously isn’t an ant. It is about 2 mm long. Hopefully you can identify it, I’ve searched many many sites.

Hi Zach,
It looks like you have a type of Merchant Grain Beetle, possibly Oryzaephilus mercator or the closely related Saw-toothed Grain Beetle, Oryzaephilus surinamensis. These are very small beetles that are elongated. According to Hogue: “The appearance of these pests in a tightly sealed package of dried food is a source of wonder to housekeepers. Entry is commonly by way of minute imperfections in the seal, but some species may bore through paper and cardboard containers to get at the contents. In other cases, infestations occur when the foods are stored in bulk in railroad cars, warehouses, and at other stops along the processing line.”

What is this?
Can you please help me identify this bug. They are found on the walls in my home. They crawl very fast and are very tiny. I took a picture next to a dime.
Thanks for any help

Please help…
My wife was cleaning the other day and found these two bugs in some dust balls under our bed as well as in our kitchen cabinets and drawers. We tried looking online but can’t find anything that looks like these two guys – we’re wondering if they aren’t babies of something else. We’re not sure what to do about them or even where they came from. Thanks for your help,

Hi Tom,
It is difficult to be certain with your photo.

Update: (10/21/2005)
Hi, The insect pictured here copied from WTB is a spider beetle. It is a bead like insect often associated with rodent infestations. I managed to find your site when pulling up pictures of “lawn shrimp” to show an employee.
