How do you know a bug bite you’ve contracted over the course of a night’s sleep is actually a bed bug? If you wake up and you notice a single bite, it’s usually a spider bite. If it’s multiple bite marks that are small and they are on your upper body, you likely have bed bugs. You can get the bite anywhere, however, bed bugs tend to bite more on the upper part of the body.
There are other signs the bites on your body are bed bugs. This includes bites of three or four that are in rows, and they tend to be very itchy.
While bed bugs will bite anyone, they only leave red, irritated skin reactions on people that are allergic to the bites. This is why two people sleeping in the same bed can experience no symptoms, or only one of the two people will see symptoms.
