What's That Bug? does not endorse extermination

Bed Bug or Flea?
My wife found this in our newborn twins’ nursery. We live in NYC and do not have pets. Very rarely have we gone out because it is cold out! Threw out the day bed and sanitized the nursery this morning. We thought it was a bed bug but it doesn’t have a head and the legs are long. Could it be a flea although it seems large? Definitely not a lady bug. It has long legs, no distinguishable head. It is flat along the sides. Can’t see if it has pincers. What do you all think?

Hi Jeffrey,
This is a wonderful image of a Spider Beetle in the genus Mezium. They are common household pests that infest grain products. It is harmless to your twins.

Expert Update: (05/22/2008) spider beetle errors
Dear Bugman,
I believe I had written earlier when looking at many of the spider beetle pictures. Almost all of the shiny brown, globular body, images are of Gibbium aequinoctiale and not Mezium species. There is a combined 2 image photo (finger and beetle & 2 beetles) of Mezium : the answer was posted by Eric Eaton, I believe. Gibbium species do not have a velvety covering on the thorax, Mezium species do. You should correct your website postings so people will have a better idea of what they have been finding.
