Insect Bites or Other? I have no pets

I have noticed several small red bumps on my skin, mainly on my arms and legs. I think I am getting these when I am sleeping but I am not 100% sure. They look like small insect bites. I called in an exterminator but he could find no trace or evidence of bed bugs. I also went to the doctor and he could not say for certain what was causing them.

Does anyone have any idea what they might be? Could it be mites, some kind of allergic reaction, or something else? I have no pets.

They could be itch mites, they live in trees and are constantly falling off or being blown off, onto your skin. I live near many trees so they are very prevalent in the summer or when things are in bloom (also found on bushes or plants in general) these bugs are microscopic, you will never see them nor will you know they are biting you. The only thing that kills them is extreme cold or taking a shower with anti-bacterial soap. They key here is you must take a shower but then not go back outside or where your shoes have been, because shoes track them in as well. Before all of this you need to wash all your linens, vacuum really well and disinfect your bedroom and house. IN the summer leave your shoes at the door, so there is no tracking the bugs through the house. I have dealt with these things for years as well as many people who live in this area (midwest, south) so, I hope this helps, i suffered for years but I do not anymore.
