I found a site on the internet that showed that 91 percent alcohol (sold at drug stores) will kill bedbugs. One will need to treat the areas more than once but it will kill the bedbugs on contact. It must be 91 percent alcohol. The stuff you buy in stores do not work but alcohol will kill them. If its really bad take everything out of the room and check the seams of the mattresses or you will not get them. Hope this helps.
