Remove all sheets, pillows and blankets from the bed and all cloth items from the floor. Place them directly into a washing machine or bag them up in a plastic bag and tie it off. Wash and dry these items on HIGH HEAT for a minimum of 30 minutes before moving them back into the treated area.
In cases of a heavy infestation it will also be necessary to remove all items from closets as well. A handy illustrated guide outlining the steps of a bedbug treatment can be found
