Put on clothes fresh out of the clothes dryer. Get a few portable heaters, fans and some wireless thermometers.
Go from room to room. Place a wireless thermometer on the floor, one under a mattress/cushion, one inside a sock drawer, one inside a jacket pocket and one on a top shelf in a closet.
Turn the fans on and heat the room until the floor thermometer reads about 130F and keep the heat going several hours. Turn everything off and go to the next room. Keep on going through the house until you've done every room.
Not a bad idea to repeat the process a week or two later.
Thank you for the advice.
