I woke up with tiny red dots on my arms and legs(tiny bites) I went to see the doctor and she gave me an antibacterial cream although it helped I kept getting more tiny red dots. While changing the bed (and I am a clean person) I decided to spray the mattress with a Raid bedbug product to be on the safe side and hundreds of tiny red spiders came crawling out of a tiny hole in the mattress. What are they and where do they come from? And how do I get rid of them?

I would appreciate all the help I can get!

They might be mites of some kind. Maybe this? http://mightycleancarpetcare.com/carpet%20cleaning%20photos/whats-in-your-mattress-cleaning-virginia.jpg or this?

Would chiggers invade a mattress? Whatever they are, I vote for new mattress also.
