Fortunately bedbugs don’t spread disease with their bites, but the bites can be terribly itchy and tend of occur in lines or groups.. They usually occur above the waist and are attracted by the carbon dioxide we exhale. When we travel, the first thing we do when we get to the hotel – NO matter how many stars its rated – check the beds for bedbugs. JUST SOMETHING WE ALL HAVE TO BE ON THE LOOKOUT FOR, particularly if we travel a lot.
