What type of doctor treat Demodex mites?

There are 25,400 microns per inch!) There is little chance two children in two separate rooms are causing each other to be 'hysterical' about bugs at the same exact time with no audio or visual clues between them.

I can help with this in many cases. For a true mite infestation, get a new bed with a vibrator or by a bed vibrator online. Mites hate water flow, air flow, vibrations, including loud music such as front row seating at a rock concert where the bass vibrates your whole body. They also hate heat, so I hot lamp such as you can place on a tripod so many feet away will drive them away, but you have to use common sense with a heat lamp, obviously, and you don't want to fall asleep under it without ensuring it won't fall and burn you or worse. The safest is to use a bed vibrator on high. Some cases maybe able to just rinse their hands and hair at the sink or add an alcoholic hair tonic on top of water. A good shower or bath seems to work for about two hours in a bad infestation. If you shower before bed, then use a bed vibrator throughout the night turning it back on as much as possible, you shouldn't be bothered with them while you sleep.

Taking a sleep medication only helps you ignore the problem, but not remove the problem. You want these things going into your nose or sinus cavities and taking up residence there. Whether demodex or another tiny invisible creature measured in microns, certain ones can cause eye damage and even further penetrate into the brain. You also use water to flush your sinuses. Demodex likes hair follicles, so wherever you have them could be a target for them. Inside the nose, the ears, eyebrows, the scalp.

Look at your surroundings. Do they get worse at certain times of the day or after certain events? When the dew rises on the lawn, many creatures tend to move at that time, so you might find increased demodex activity then. Also if a neighbor is doing lawncare with mower and blower, that will excite the demodex and other bug populations to go on the move. Rain will have that effect also. Certain people with hearing loss and demodex don't hear the rain but suddenly feel an itching after following a lot of guidance, and are puzzled until they find out it's been raining. After a number of times, they catch on. Peremithrin based sprays work well for outdoors and you can also buy the little white container of NIX and spray just at the foot of your bed between the mattress and box springs because any bugs in the bed will eventually come in contact with it and die; so don't spray all between them, but just at the foot of the bed. Once a month around the perimeter of the home should be fine. Or if in an apartment or condo, you'll have to spray inside where separate condos connect to yours.

Cultivate the habit that when home, you take a few extra showers every day, or wash your face and hair every time you feel activity increasing. If you wash your hair and it doesn't itch for two hours, then restarts, that's a serious clue you are dealing with mites. The military also has products that ward off insects that are now available in stores.

I mentioned air flow. I know one man who bought a shop fan at a local hardware store and turned it on high. The problem ended immediately in that room and he never slept so well in his life, he says. Water, air, heat all have a flow and they all drive demodex away. If you can handle loud music, while I think a bed vibrator makes more sense, loud bass sounds also drive them away. Movement like jumping and dancing and stomping your feet also disrupts mites.
