Definitely I have a case of birdmites. Struggling with this for 6 months now. Financially drained, unemployed & seriously, seriously about to live on the streets. Threw out all furniture from one home last November & now ready to just walk away from present home as all my furniture & clothes are infested again. Unable to get any decent sleep & my car is also infested inside. No money & don't have any way out of this problem.
It is called formications and there are several different things that cause it, including illnesses, hormones, fevers, and certain medications and drugs.
If you Google "formications" you'll find a number of websites (wikipedia, et.al.) on it and you can see if any of the causes are a possibility for you. Most of them are treatable.
