Probably NOT Foreign Grain Beetle

We had a bit of trouble with this one, and we are not certain that our identification is correct, but it is possible that you have an infestation of Foreign Grain Beetles, Ahasverus advena, also called the New House Bug because it is”common in homes (esp. newly built) and grain storage facilities” according to BugGuide, which also indicates it feeds on “Molds and fungi growing on damp grain, grain products, and other materials.”  Sadly, we realized our identification was incorrect the minute we found the University of Arkansas Arthropod Museum website which has a nice page devoted to the Foreign Grain Beetle and which indicates:  “They have two conspicuous and diagnostic round lobes on the prothorax right behind the eyes.”  Those lobes are missing in your beetle, so alas, we have drawn a blank on the species identification unless the lobes are just not visible because of your camera angle.  There are a multitude of insects that will infest stored foods, and we believe this must be one of them.  If the actual identity is critical for you, and if none of our readers come to our rescue here, we suggest you begin scouring the internet for potential Grain Beetles like those profiled on the Grain Beetles page of the Pest Products website.

    I have these exact same tiny bugs all through my laundry room and bedroom. I have sprayed and vacuumed and sprayed to no avail. I noticed them after we came back from camping almost 5 months ago. I am at my wits end. We have animals so to fumigate the house would be hard. Is there any other solution?? Please help.

    I know this is a dead thread but for anyone else looking it looks to me like some kind of grain beetle. Not a sawtooth or merchant, too smooth for that, doesn’t really look like a grain weevil either.

    I’d approach their removal the same as other gain beetles.

      Thanks for the comment Craig. The beauty of our archive is that though there may not be recent activity, our threads never really die.

    does the beetle type in that photo have a mint-like smell to them when they are picked up or squished? Beetles just like that pester me in groups in my pen containers. I also see them in my room. Each year is worse.

    I’m no expert but I’ve experienced an outbreak of a similar looking beetle and have been searching the web non-stop in the last couple days so I’ve seen a large number recently. I believe that the one in this post is the either the red flour beetle, or the confused flour beetle.

    I think I have this same bug, but it is bigger then a grain beetle. Notice it jumps after I squish it. Can’t find anything online.

    Found the same little brown beetles in my bed. They can fly. Size is from 1 to 5 mm. Fine striations are visible on their back when looked at with magnifying glass.

    After a bit of research, I’ve concluded that these are the “lesser mealworm” beetle. Latin name is Alphitobius Diaperinus”. This species of beetle is parasitic to birds, both domestic and wild, and even mammals. It is known to feed on live animals. It is spread world-wide. It carries & can transmit other parasites.

    Here’s why I concluded these are A.D beetles. Since 2 months ago, when the migratory swallows came back in their nests in the inner roof above my apartment’s ceiling, we’ve been finding these little brown beetles all over the apartment building. That’s the connection to birds. These migratory swallows winter in southern USA, and the little beetles could be hitchhiking a ride on the birds on their way north.

    Another tenant has also found them in their bed. If these were grain beetles, they would be in the food, but we did not see them in foodstuff at all. I’ve gotten bitten at night. These beetles seem to like body heat and seem to be carnivorous.

    I found their nest under my mattress and in my sofa, had to throw that stuff away. We’ve put sticky traps in many places, and that little brown beetle is the only bug found in the trap.

    I’ve started spraying my apartment with solutions of cedarwood & eucalyptus essential oils. I got rid of clutter. Am now spraying belongings and packing in air-tight containers, to be stored for a while.

      Since you didn’t include a pic, nobody can back up your conclusion but it sounds like bed bugs to me. You might want to double check.

      • Tangerine says:

        I took samples to the local health unit, and they said it was a beetle of some kind.
        It has wings under its shell, and we’ve seen them FLY.
        Bedbugs don’t have wings nor fly. No bedbugs have shown up on our sticky traps.
        I submitted a photo with a previous post on this site, but it hasn’t been posted here, don’t know why.
        If you google the name of this beetle “Alphitobius Diaperinus”, you will come across photos, which look exactly like the bug we have.

    I know this is old but given that they are everywhere (for commenters too) and not just in food (or the kitchen) then perhaps this is one of the Powder Post Beetles (Lyctinae) that infest wood and are in the same superfamily as many of the Carpet (and Deathwatch) Beetles.
