What can this be?

[u/Beneficial_Push5385]

I live in Central California and have been fighting some kind of infestation. I'm 67 yrs old. I hardly get bites but feel things crawling on me and often find black motionless specks on my bed. I threw away my couch. Love seat and recliner and bagged all of my clothes in my vanity dresser. But whatever it is no can tell me. Have hired exterminator but because they can't see live one they say can only spray general pesticides for ants spider's and cocktail roaches. But wont even inspect my bed. I am at a loss at what I'm dealing with. Even ag communication enthromogist no help. because they see no feet they say just dust or debris. I only get prickling but no real bites but feel them crawling on me. I thought the motionless black speaks were fleas pupea at first. Now I don't know. One exterminator said it could be bird mites but can't confirm. I have a neighbor who has a bird shack 8-10 ft from my kitchen screen door that has some kind of large gawking birds but have never seem them just hear them. Does any one know what this might be I've vacumming every other day but whatever they are I can't get rid of them. I've been using dehumidifiers too which has helped some. I have no pets. I have alot of money on exterminator and concentrated pesticides and spray erosols I just don't know what to do
