Entomology (Study of Bugs) - biting insects


Expert: Walter Hintz - 10/24/2009

Question
QUESTION: For the last few weeks my room mate and I have been feeling little sting like bites but there is no sign on the skin of a bite, and nothing is seen. What can that be?

It happens by the computer, on the bed, in the living room, sometimes even outside the home and is very worrisome as well as bothersome.

ANSWER: Hi Troy
When you are bitten but cannot see a bite nor an insect that did it, it occurs to me that this is an allergic reaction to something.  Perhaps a food allergy or contact with something different.  Have you been eating something different or changed soaps or anything

---------- FOLLOW-UP ----------

QUESTION: It is happening to my room mate and to myself so it is not an allergy, but some sort of biting stinging small insect, I think. If it were bedbugs or a spider or something else I have looked up on the internet it would leave a raised itchy bump but these bites are stinging itchy but do not show and do not last a long time. What small  invisible insect could be doing this. I live in NYC btw.

Thank you for answering.

Answer
You can rule out bedbugs and spiders because we can see them. I can identify insects only when I can see them but I am not a doctor who can recognize skin ailments. There are no invisible insects. There are biting gnats called no- see- ums but they leave a bite mark.
You cannot rule out an allergic reaction because your roommate also has the same problem  You are sharing the same environment and allergic reactions can be environmentally related.
 I wish I could be more helpful.  My only suggestion is that you and your roommate talk to a dermatologist since this appears to be a medical problem
