Hello, I have been having a problem with bites on various parts of my body for several months now. Nothing always happens for a while, and then all of a sudden there are bites all over the body. Nothing helps with lubrication with phenistil or corticoid ointments. I don't know what it is all the time I haven't noticed anything in the whole apartment until all of a sudden now I've discovered the bricks of the apartment these bugs don't know anyone what it is? if it could be thorns?
