Wash your bedding, curtains, and clothing in hot water and dry them on the highest dryer setting. Put stuffed animals, shoes, and other items that can't be washed in the dryer and run it on high for 30 minutes or more. Use a stiff brush to scrub mattress seams to remove bedbugs and their eggs before vacuuming.
