Wow - thanks everyone!

Jill is also going to ask her landlady if she can sleep in the spare room upstairs. That will help.

I guess it seems that her landlady IS overly tight on energy and bills - then again, I suspect most tenants don't have the health problems that Jill does.

I think there IS carpeting in the room - and I bet some nasty critters are hiding underneath it. Wonder if it could be ripped up and replaced with a nice thick area rug....

Thank you all...still open to ideas if anyone has them!
