Small bites over body - potentially bugs?

My roommate and I had bed bugs. At first, I never saw the bugs. My skin reaction to the bites wasn't as severe as my roommate's reaction. He was sure we had them because a friend, where he slept over sometimes, had them. He figured out that he had brought them home with him, and that they were in the couch. He felt the bites and saw the places on his arms when he was on the couch. He often fell asleep on the couch. The bed bugs are attracted to the carbon dioxide you put out when you breath. They wait till you are still to bite you - that's why they bite you in your bed. It's why they bit my roommate on the couch - he often fell asleep there watching tv. However, he was trying to save money, so he bought some spray at the store. It only killed them on contact - but they were hiding deep in the couch, so this never wiped out the babies or eggs that were always hidden in the couch.

The bugs finally got into my bedroom. I got a bite and found a dead one (I mashed it in my sleep and there was a blood spot the size of a pea on my sheet from this) in my bed when I woke up. I saw that my roommate's do it yourself method didn't work, so I called an exterminator. It worked eventually.

This is what the exterminator did. He charged us $650 because our apartment is not that big. A large house costs up to $1,500. The bed bugs in my bedroom were living in a chest of drawers about two feet from the foot of my bed. They were crawling across the floor and up into my bed each night to bite me and then back to their home about three feet away from my bed - so they don't always live in your mattresses or box springs. I had to remove everything from my room except for the furniture. As I removed it, I had to put it into sealed garbage bags to prevent the bugs from getting out - I didn't know where they were living yet when I did this. Then the exterminator came and treated my furniture and mattress and box springs and room with chemicals. He installed a bed bug proof cover on my mattress and box springs to seal in any bed bugs and keep out new ones. It can take 18 months for them to die - because they can go that long without feeding if they have to. Upholstered furniture and mattresses have areas where the exterminator cannot reach - thus the need for the mattress covers. In addition, I had to wash or dry clean every cloth item that I took from my room and dry it on high heat for 30 minutes to make sure any bed bugs/eggs, etc were killed. I had to inspect all non cloth items before returning them to my room. I had to wait two weeks before putting anything back into my room. This worked. I found the bed bug shells and dead bed bugs after I removed everything and the exterminator sprayed. Some came out of hiding in my chest of drawers because the spraying ruined their hidden nest, and they were sick from the spray.

In the living room, nothing killed them in the couch, so we had to take it to the dump to be curshed.

They could be either bedbugs or fleas - either way, they're probably living in your mattress, rug, and other textiles in your room. You could fumigate the room you're finding them in - that's probably the only way to get them out of the mattress. There are also treatments that you could use for the rug, curtains, etc.
