If you submerge bed bugs in 70% ETOH solution, it will kill them. However, if you just apply it to a surface, and expect it to kill bed bugs that crawl over it, that won't work. The ethanol will evaporate quickly, and once it's dry, it's not effective in killing much, although it might do an okay job repelling bed bugs for a little while, but ethanol isn't a safe chemical to expose humans to.
