Entomology (Study of Bugs)/tiny thin black bugs


I have found these very tiny think black bugs on a bed where my cat sleeps.  They were under a gym bag.  There was some cat fur and some flea dirt. My daughter noticed there was movement in among the black flecks.  They are so tiny, you almost need a magnifying glass to see them or at least stare a long time to catch the movement. They are worm like. I put some peroxide on a cloth and wiped over the area.  This seemed to kill them but I am concerned about what they are, are they harmful to my children, cats, dogs or pet rodents? How do I get rid of them? And, how do I prevent them from returning?

Thank you!!


Without at least a clear image of the creatures in question (preferably a specimen), I can't even tell you if they are insect larvae, millipedes, or something else.

I also do not offer pest control advice.  We have too many chemicals used irresponsibly as it is.  

That said, a thorough cleaning of your household and belongings seems in order judging by your own description.  Eliminating food sources for insects and other arthropods usually reduces problems substantially, if not eliminating them altogether.  Good luck.

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
