Although helpful, rubbing alcohol only provides temporary relief against bed bugs. According to an article in Science News, during their test, rubbing alcohol killed only half of the bed bugs that were sprayed directly with it. Rubbing alcohol comes in 70% and 91% concentrations.  If you are going to spray bed bugs with rubbing alcohol, it is recommended that you use 91% Isopropyl rubbing alcohol.  Spraying bed bugs with 90% isopropyl rubbing alcohol will kill them on contact, however, Isopropyl alcohol should only be used for spot treatment to kill single insects, not an infestation. For a full and proper treatment of an infestation, Bed Bug Patrol is a much safer and more effective solution that is safe for use around the home, and once dry, is safe around children and pets.
