any ideas what this is.. were all getting bites? is this the cause???

weve all been getting bites.. including my 3 month old baby.  I wasnt sure what it was.. got pest control out and they couldnt find anything either.  I purchased some roach traps and couldnt see anything at first apart from the odd spider/woodlice.. then i noticed by looking a little closer, some strange beige looking things (originally thought it was some sand grit).  they are approx half a mm in size if that.  got a microscope and zoomed in on it about 25x and came face to face with something that looked like a


any ideas what it is.. and can it bite?  im desperate to find whats eating us and apart from this sample.. im clueless.


Thanks for looking,



  • Looks like a mite, probably house dust mite: They do not bite but are a major cause for allergies because of their excrements. The allergy does not express itself as if they are bites. Do you have cats or dogs in the house? Then perhaps there are fleas that might be to blame.

      • In this web link is a picture of poultry lice - not far off it seems to me. If you google poultry and bird lice/louse there's loads of information about how prevalent the problem is, and what the solutions are. This seems like the place to start. Good luck. It must be awful,

        • The image of the poultry louse does not match at all. The photograph clearly shows eight legs, the poultry louse has only six (and never will get eight, contrary to earkly instar mites...). I maintain the photograph shows a mite. If they truely were feeding on poultry first, then gone for a while, and now back in strength they need to have fed. If they had been feeding on you and your loved ones, then you would have seen them near the beds: these mites will stay close to the food source: either the host or it's nest; meaning near the bed. I don't think the mites cause your problem.

      • Exactly what species of bird did you have - every bird mite/louse is different.

          • OK folks - I have show this to our mite (Acari) specialist who has provided the following observations/comments:

            From what I can make out, the specimen in the image looks like a mite of the family Cheyletidae (order Prostigmata). 

            A  likely candidate is Cheyletus eruditus, but I would need to see the  specimen to confirm. By chance this species was the subject of a recent Species  of the Day:


            Cheyletus eruditus is a predator and generally regarded to be a 'good' mite because its diet includes pest mites and insects, e.g., flour mites, dust mites, cat flea eggs, booklice, larvae of storage moths and beetles. It is often found in stored foods (mostly flour and whole grains) and storage containers and buildings. Other habitats include mammal and bird nests, animal bedding, poultry litter, house dust, haystacks, soil and plant debris. The presence of C. eruditus in infested  materials has been blamed for causing dermatitis in humans handling them.  Cheyletus malaccensis, a species that occurs in similar habitats to  C. eruditus, has been shown to feed on human body fluids. This  resulted in an allergic reaction and the formation of small itchy bumps.   However, such reports are uncommon and, because of the history of birds  being kept, examination of other trapped specimens would be advisable to check  whether there are other species present that could be causing the reported  symptoms. To find the source of infestation, a good start would  be to see whether there are abandoned bird nests in the loft and removing them  if there are.

                Goes to show we Homo Sapiens are a species that evolve alongside other species that may irritate and bite us from time-to-time by way of their right to survive...


                Our answer, as a so-called 'intelligent biped', is to exterminate so many fellow creatures because we can't put up with an occasional scratching.
