Spouse has red spots like bed bug bites and itchy. We both itch at night mostly and in crevice area of joints. Some prick type sensations and crawling sensation but no bugs found. We treated for bugs including bed bugs with bug bomb and sprayed mattress and box spring. We washed all the bedding. We then found tiny pinhead size black bugs on my phone and plugged in charger. Nearby our hanging clothes and hangers and a radio close by were full of the tiny black bugs. Even after treating for the bugs there are still tiny pinhead black bugs! What is this tiny bug and does it bite, cause itching, harmful to our health!
