I found three bugs that look just like these guys on my box spring and under my bed this evening. They didn’t look quite like bedbugs to me (very rounded instead of the flat images I’d seen for bedbugs). My question is, are spider beetles known to roost in beds?
Not particularly, Rob, but it is amazing what bugs you will find when looking for bed bugs. Lots of us have found spider beetles.
Hi, I’ve got the same thing. I just threw out my box spring thinking maybe that’s were they were staying. I’ve got a collection of welts on my left shoulder blade.
They burn and hurt, but no bite hole. How are you getting rid of them?
Hi Julie,
You may have spider beetles, but we are told they do NOT bite people.
You may or may not also have bed bugs which are causing your bites. If you think you may have bed bugs, here are some tips on getting a definitive answer, as well as some other possibilities for what might be causing the problem.
I def have these beetles how do I get rid of them and tips on keepin them from coming back
Kia,
Spider beetles do not bite. Any pest control professional should be able to help you.
I recently moved from a bed bug infested apartment where one of my roomates had brought them in from staying at a friend’s place and can not go thorugh another infestation! This afternon I found a bug crawling on my wall that looked exactly like the spider beetle image posted above and I was wondering if it was common for bed bugs to come out during the day or if it was actually a spider. In my last apartment I had found what looked exactly the spider beetle in the bathroom, but had assumed it was a bed bug. Thanks!
Hi Joanna! I fully understand your concerns about going through another infestation, having dealt with bed bugs.
However, if you have something and you’re sure it looks like a spider beetle, it probably is one. (You could probably walk into any pest control business with a sample and get this confirmed).
They do NOT bite and are not a big deal, though I understand they can be stored grain pests. Lots of us have spider beetles. And they’re not spiders, but a kind of beetle.
Having had a pretty terrible bed bug infestation before, about every 3 – 6 months i go through a fairly serious “bedbug scare” where after finding any sort of bug bite or itchy spots i take preventative measures by cleaning everything and putting down pesticides from the hardware store. Since then i haven’t had another infestation and don’t know if these efforts help that or not.
Anyways during the last two scares i found these beetles and am curious if they are at all similar to bed bugs in their resistance to pesticides?
I don’t know enough about them, Brett. If you really want to know, feel free to copy your question to our forums: http://bedbugger.com/forum
Be assured that spider beetles are not a problem and don’t bite.
i see a spider beetle about once a week or so but i have bites and i havent seen a bed bug. i was told dat spider beetles dont bite but wat is it dat is biting me???
We, too, have spider beetles. We’ve also had sporadic bites–they are very itchy, but are small and go away in 2-3 days. We had a bed bug problem 1 year ago, and while I’m pretty confident these are NOT bed bugs, I am wondering what they might be? Anyone have any thoughts?
i would like to know, why would spider beetles mainly be upstairs in an apartment and continue to be there after a pest treament.
Gabb and Hap,
Bed bugs hide easily. It’s rare to see one. So it is entirely possible you have bed bugs (or some other cause of your skin problem) and also happen to have spider beetles.
Please see a doctor to rule out scabies, folliculitis and other causes. I suggest you also have a knowledgeable and experienced pest pro rule out (or eliminate) fleas, mites, or bed bugs in your home.
In rare cases, we have heard people can be so sentitive to insects that they react allergically merely to the presence of an insect which does not bite.
However, so many people who are searching for bed bugs find spider beetles, and I suspect most of them do not fall into this category.

I do not know, sorry!
