Many people believe bed bugs come back after treatment or it has been ineffective, when really they're just noticing more of the bed bugs because they are no longer hiding. While treatments will kill the bed bug population, the aftermath still needs to be cleaned up. It is important to wash and dry all bedding on high heat and vacuum thoroughly to pick up and remove any leftover nymphs and eggs. Be sure to empty the vacuum outdoors and away from your property to avoid any critters making their way back in your home if there were survivors.
