Treatment Cycle:

For a bedbug infestation, a treatment of the affected bed should be done at least once weekly for three weeks, or until the infestation is eliminated. For prevention of bedbugs, a treatment can be done monthly or whenever the user wishes to treat suspected items.

  1. Prepare your bed for heat treatment:
      • Remove excessive blankets or pillows that may impede airflow. The GoodKnight is designed to work with a single set of sheets, a comforter and one (for twin & twin-XL) or two (double & queen) pillows. Excess bedding can be heat-treated with one cycle in the clothes dryer. 
      • Place any overhanging blankets on top of the mattress to help maximize airflow.

  8. turn the dial Turn dial on control box clockwise until it stops (full 3 hour treatment). The timer will automatically shut off the heater after three hours. Running a treatment shorter than three hours may not allow the bedding to get hot enough to sterilize the bed. Do not tamper with the control box.

Please use caution when touching items that may be very hot. For your comfort, let the bed cool off for about half an hour before using.

Checking and Changing Traps

For a bedbug infestation, check traps at least once weekly for three weeks, or until the infestation is eliminated. Keep track of any new bedbugs caught in the traps. No new bedbugs in the traps is a good indication. For prevention of bedbugs, check traps monthly or whenever you suspect bites.

CAUTION: Glue traps are very sticky. Avoid making direct contact with the glue, or having any objects make contact with the glue. Glue can be cleaned off with vegetable oil.


  1. Lift one side of the mattress support at a time, and hold it up with the supplied Prop Rod. Make sure the Prop Rod is positioned correctly. Be careful, the mattress support may be very heavy.

  2. Check the traps for any bedbugs. If the traps are dirty, replace them with new traps.

  3. To replace a trap, first remove the dirty trap. Old traps can be folded in half with the glue on the inside to prevent the glue from getting stuck to anything. Discard the dirty traps.
  4. Peel the wax paper off the new trap, and push the center hole of the trap directly over the peg. You can order replacement traps online soon.
  5. Carefully lower the mattress support back down over the pegs. If the legs do not slide over the pegs right away, give the Mattress support a little jiggle to get the legs to fall into place.
