Bed bugs can be a real problem to get rid of once you get them. But even if you are really careful, they can sneak home with you after vacation or a stay at an unhygienic friend’s house. Thank goodness rubbing alcohol can help kill these nasty pests. Fill a spray bottle with rubbing alcohol and spray it generously over your pillows and mattress. Since bed bugs lay eggs, it’s important to repeat this process several times to completely get rid of them.
