Catsmine guess looks pretty close.
I hear that they are not fun to get rid of, but I suggested methods that worked for him. He was a student and didn't own a vacuum cleaner.
Vacuuming is prudent and the bag needs to be thrown out.
It's prudent to try to figure out how you got the infestation and how far from the bed it has spread. All areas have to be vacuumed thouroughly.
Pesticides may be necessary.
Remember that they feed on dead skin flakes.
Furniture nneds to be vaccumed and examined.
So, try to determine how you got them. Recent hotel stay or evena visit to relatives. This may give you a clue to how much are is involved.
You WILL have to wrap the bed in plastc wrap. Shipping wrap would be an ideal material. Wrap the pillows too.
Wash in hot water. Bad the sheets in the room, so the investation doesn't spread all over the house.
I'm sure Catsmine will agree and can suggest pesticides.
