It's a Dermestid, probably Anthrenus verbasci (Varied carpet beetle). Larva up 
top and cast skin further down below it. Their peak adult season in Virginia is 
in early-mid spring. We remove dozens of adult specimens from windowsills 
during this time-frame, but see them here and there throughout the summer. 
Seeing a larvae or two this time of year is pretty normal, but if it were me, I 
would check any rugs/fabric in the area to make sure there are no more lurking.

It looks like this fellow may have made a meal of another insect on the very 
top of the glue, but I can't tell for sure form the photo. I have actually seen 
traps where the VCB larvae devoured another dead insect on the glue and didn't 
get caught themselves!

I've managed to get a better image, I think. It's attached.

Unfortunately, that image is too small to identify what you've got there.  Is 
there a chance you could take a higher resolution image?  You can send it to me 
off list if you want.  I'm not an entomologist, but there are certain pests 
that I can confidently identify.

The picture I linked to is just one that I know is a carpet beetle larva; I've 
now attached an image of one from my own trap, with the pest in question 
circled in red. It's not a great image, so I don't know how much it will help, 
but that's what I'm looking at.

I'll try putting some traps in areas with more light and see if I catch any 
adults; my traps are mostly in dark corners now. Fluorescent lighting is the 
only source of light, the windows in the building were covered with plywood. 
I've found them in traps in various place throughout the building, so 
controlling them will likely be a pretty big challenge.

[pestlist] Dermestid beetle bait for sticky traps

Hi All -

Over this Thanksgiving Holiday (Nov. 21-26), in an effort to pinpoint  
a possible infestation,
I will set out additional sticky blunder traps in a room where I  
noticed high numbers of Varied Carpet beetles and Odd Beetles, adults  
and larvae.
The old traps in the room were replaced in October after being out for  
several months.


The sticky blunder traps with high numbers of larvae were in the  
room's only two (sealed) window sills, which are just above the level  
of the floor.
These additional Thanksgiving traps will be on the floor, adjacent to  
flat file cases and book shelves, in a grid pattern, all over the room.


These additional traps will need to be picked up after just 5 days, so  
I want to put a bait in the traps to attract dermestid beetle larvae.
The first thing I thought of is sliced turkey lunch meat; just a tiny  
sliver in each trap.


Has anyone tried this? I'd love some tips!
What do folks think of that bait choice?
I hope the Museum Pest List  community will have a suggestion for a  
cheap, easy to buy, not too disgusting bait to use.


Thanks -

Yes that is definitely a dermestid larva – not sure specifically  
which kind.  I also see a psocid on the trap indicating that you  
have some moisture in the area – the psocid is below and to the left  
of the speck of dirt.   Some of the other debris on the trap (upper  
edge) kind of looks like larva that have been eaten by other bugs.   
How long do you leave your traps out?  I have seen situations where  
a trap with dead things on it becomes the food source.   The other  
question I have is how many dermestid larva are you seeing?  1 or 2  
occasionally, 10 regularly or a whole bunch?  The traps should be  
able to tell you where the worst of the problem is.


I use a bodelin proscope – another digital microscope – for this  
kind of thing.  If you are in the market it is worth checking into.  http://www.bodelin.com/proscopehr

Definitely looks like carpet beetle larva to me.  There are a few reasons why 
you might not find the adults.  One could be that you don't currently have any; 
once they laid their eggs they probably left your building or died somewhere.  
The larva will eat the dead adults, thus destroying the evidence.  The adults 
are also attracted to light.  Where are your traps?  If you have windows or 
other light sources in the area where you've found the larva, try putting traps 
near those light sources.

Carpet beetles are incredibly dangerous for your collection.  Try to find out 
where they are coming from and isolate any infested materials as soon as you 
can.  Check items closest to your sticky traps, and add more traps to help 
pinpoint where they're coming from.  Carpet beetles can thrive just on hair and 
debris that naturally accumulates in corners or in cracks in the floor, so I'd 
recommend a thorough cleaning using a vacuum with HEPA filtration and disposing 
of the vacuum bag immediately afterwards.

Good luck!
