One of the best travel tips that I ever got came from my Terminix man. I was preparing for a vacation when it was our routine scheduled Terminix appointment. He noticed all of our suitcases and the prep that I was doing to get ready and mentioned to me that bringing in bed bugs, roaches and other pests were normally because you pick them up while traveling. He said that even if the place that you are staying isn't infested that when you fly you can pick them up from the luggage that is next to yours.
Travel Tip - Do not bring in ANYTHING after traveling to prevent bed bugs and pests
After traveling he said that you should empty all of the contents of your suitcase onto a blanket and leave it outside for several days only bringing it in to go straight into the washer. He suggested washing those items in hot water to be safe. Since we have a garage we have followed his advice since. The first think we do when we get home from a trip is to unload our luggage into the garage empty it on a blanket. In fact we keep a huge moving blanket in the garage just for this purpose.
He also suggested that we keep the suitcases unzipped and leave them in the garage for at least three days. This is a great travel tip and when it comes to bringing home bed bugs or other pests it is a step that we are not willing to skip no matter what. In fact it has paid off for us because we did find a baby roach in one of our suitcases once that we were able to keep out of our home as a result of using this tip.
We hope that this tip helps you too!
