Hi, I have a long term pest that is microscopic. You feel it boring in, the bites or boring hurts.tingling when it moves under skin, then you feel it pop out.They love the thick skin on my heels ,toes the most.They like warm humid areas.Have dehumidifier,and tried all I could find to kill them.I can roll it on finger, but not squish,it is hard, and not seen. may be clear or flesh colored.Seem to go quickly for tiny bug.What are they? How do I kill them without poisoning me?They like my scalp, too. Scabicides ,lice meds do nothing to them. I have been chased out of my home due to them.Help!!!!
