I am not able to identify this bug/insect. I stay in Dubai and have been noticing this bug/insect in my apartment since a week now. It is so tiny that it's difficult to notice. The image below has been taken using a DSLR by placing it on a book page and cropped to more than 100% zoom.
I don't know the source, can feel it crawling on my skin and that's the only way to see it. One good thing is it cannot fly.
I went through all the questions about insect identification, but couldn't find any closest match for this. I also compared it to a book lice, but it's nowhere near to it.
I suspect it bites and leaves the skin itching with red spots similar to a mosquito bite. Does anyone know about this bug if it is harmful, and how to get rid of it?
