what is this reaction from? allergy or bug bites?

I don't know if this is an allergic reaction to bug bites or something thing else but the only things I've changed is laundry detergent and the place I live at. It started about a week after I moved in. I just wake up in the middle of the night itching all over mainly on my feet and stomach and chest at first then my legs hands and wrists. They are tiny bumps a little bigger than a pencil tip and they are the same color as my skin and if I barely touch them they itch really bad and the sensation doesn't go away for awhile. And I really badly itch when I first wake up. So what could this be.
