OK... Voice of reason stepping in... LOL!
We dealt with a MAJOR infestation of the nasty little things. Orkin came in. Mattress covers, pesticides. They came back. Tried heat in the worst area (Onyxx's room). They came back. Tried all the home remedies. They came back. Tried stuff you buy online. They came back.
We found a pesticide that, coupled with heat, worked.
We still find one occasionally. They're pervasive little (ahem) buggers.
Good news though. They're annoying as all get out, but aside from itchy little welts (and not everyone gets those), they're harmless. Just icky!
Don't get too crazy about it though. If you have a small spray bottle, fill it with rubbing alcohol. Then you can spray your purse, luggage, lightly with it. It will scare them off, as well as kill them. (We've gone through GALLONS of the stuff, but they have since avoided Jett's room like the plague - BEFORE we used the pesticide.)
They leave me alone, too. I think they know I'm the alcohol-sprayer-person.
There are none in my new bedroom, or in the house, at this time. That doesn't mean I won't find another someday. But now I know it's not being dirty or nasty people that causes the infestation.
Hugs. And if the fear gets debilitating, please, see a therapist.
