I will be buying more just to make sure the bedbugs do not try to stay or come back.. This really works. I put about one cup in every load of laundry I do as well as spray my already washed items in the closet (spray bottle mixed with water) and other places like pillows, etc.. I use another brand for my floors because it works and I do not want to mix the chemicals as that will render both unusable. I would tell anyone dealing with bedbugs to stock up on this and keep at it until they are gone. You must treat your baseboards about every thirty days, cracks, crevices (caulk) keep vacuuming constantly (spray vacuum with Crossfire) and keep washing clothing in hot and add the Premo. You can even wash in cold or warm as long as you have the Premo in your laundry. You can have laundry soap and Premo together. BUY THIS. Save yourself stress and tears. I have dealt with these for too long. GreenAkersPest YT is helpful.
