White Marked Spider Beetles

Dear Mrs. Payne,
These are Longhorned Borer Beetles in the family Cerambycidae, and they resemble the Ivory Marked Beetle, Eburia quadrigeminata, but they seem very small and Idaho is considerably west of their range as listed on BugGuide, so normally we would discount that as a possibility but for one bit of information posted on BugGuide.  According to BugGuide:  “Notorious for emerging from furniture after as many as 10-40 yrs.  Delayed emergence of E. quadrigeminata was discovered from a birch bookcase 40 years old (Jaques 1918).”  Larvae from this family are wood borers, often remaining in the larval stage feeding for several years.  If infested lumber is milled and turned into paneling or furniture, it is possible that the larvae might survive, and individuals in that situation may emerge many years later and they are often considerably smaller than individuals that develop in nature.  According to BugGuide:  “hosts include a wide variety of hardwoods (oak, ash, hickory, locust, chestnut, maple, elm, beech, cherry); larvae bore in heartwood.”  It is possible that you bought a piece of furniture made from one of those trees that was milled in the normal range of the Ivory Spotted Beetle, and that could explain its presence in Idaho.  That is speculation on our part and the beetles you found might actually be a local species, but at this time, we have not been able to find a likely candidate.  We will seek a second opinion on this from Eric Eaton and our readers might also be able to provide some other information.


Whitemarked Spider Beetle

Eric Eaton Responds
Way too tiny for Ivory-marked Longhorn, but I see the resemblance otherwise.
These are spider beetles, family Ptinidae.  Probably the White-marked Spider Beetle, Ptinus fur.  Here’s the Bugguide page:
I rarely see these, but they are well-known “stored product pests.”

Indian Meal Moth

This is an Indian Meal Moth, a common, cosmopolitan household pest that has larvae that infest stored grain products.  Check the pantry for an old box of corn meal or oatmeal, or check for that bargain bag of pet food or bird seed.

These little moths are all over my house and stick to the walls. They are about a half cm wide and a half cm tall. I just have no idea what they feed on or how to get rid of them. Please let me know! Thanks!
I live in Abu Dhabi… Very hot weather.

Carpet Beetle

Varied Carpet Beetle

Dear Elliott,
This is a Varied Carpet Beetle, Anthrenus verbasci, a common household pest.  The larvae of Carpet Beetles are often found indoors where they feed on shed pet hair and other organic materials.  Adults feed on pollen and though they do not damage the home or its furnishings, they can become a nuisance when they are plentiful and they gather on window sills in an effort to get outside.  They often die indoors.  We have been receiving Carpet Beetle identification requests daily right now, and we have not posted a new image recently.  Your image is of a good quality, so we have determined it is time for a new Varied Carpet Beetle posting that can be featured.

Subject: Bed Bug or Swallow Bug?
Location: North Central Alberta, Canada

I have recently stumpled upon a bit of a rapid infestation at my camp out at work in northern Alberta, we have had swallows every summer make nests underneath the overhang of our roof outside. I came on shift and ended up seeing a huge influx of these little buggers, the majority of which were occupying the corners and cracks around appliances in our kitchen, the kitchen window is directly below where the swallows had made their nests outside. I’ve heard that during the winter months the swallow bug can hibernate and awaken during the start of spring. They have a few that have made their way into the bedrooms but i can see no evidence of any burrowing or making homes in bedding, the majority have all been found in our kitchen. It would be a great help if anyone had any insight into what exactly im dealing with here, i’ve already cleaned out my belongings and will not be staying inside of the trailer until the bugs are gone but determining what they are would be a big hel p before creating a plan of action, this is in a very remote work camp so its a fair trek for a pest control to just poke their head in without knowing what they are up against. Thanks in advance!

Probably Swallow Bug

Probably Swallow Bug

Dear Taylor,
We haven’t the necessary expertise to distinguish between a Bed Bug and a Swallow Bug, but circumstantial evidence indicates this is most likely a Swallow Bug.
  We also suspect that if they are Swallow Bug and there are no swallows to feed upon, they may be opportunistic and feed on human blood.
