How Can Insect Bites On The Skin Be Treated?

Ok, I ve been fighting an infestation of very tiny bugs in my bed, in my hair, and all over my body. I have been bitten on my joints, mostly. Some of the bites swell rather badly, like on on my elbow. Most are very small and not problematic. Sometimes they seem to burrow into my skin, with a lot of irritation to me, and soon afterwards little itches spread from that area. I have caught what I think are the culprits on some clear packing tape. Under bright light they show up as white things. some seem to be in a larval state, and some seem to have legs. Even with a good magnifying glass, I can t make much out. I need a scope. They are not bothered by hot dryer temperatures. What am I dealing with and how do I kill them?
