Dryer sheets will help to repel the bed bugs and keep them away from locations you don't want them to be at.
But the dryer sheets won't kill them or actually get rid of them.
The best way of getting rid of bed bugs is by fumigating your home or having an exterminator do a heat treatment to kill off the bed bugs.
You could also add some pesticide to some water and put it in a upholstery steam cleaner to clean your upholstery and get rid of the bed bugs and the bed bugs eggs.
