The best way to tell if you have bedbugs is by looking for bites on your skin. Bedbug bites tend to be red and itchy. These bites will often be in straight lines. While other insects may leave random lines, bedbugs tend to leave uniform, straight rows of bites. Although bedbugs are not known to spread disease, the itching caused by the bites can be painful and cause the skin to break, which can lead to infection. Some people may even experience an allergic reaction to the bites.
Bedbugs can bite any part of your body. While you’re sleeping, they can bite you on your arm, leg, or other exposed body parts. Unlike mosquito or flea bites, bedbug bites do not form a red dot in the center. They also tend to remain on your skin for longer than mosquito bites.
If you notice the bites on your body, you should wash the affected clothes immediately. If you can’t wash them right away, put them into a plastic bag until you can wash them. You should avoid touching the affected area, since the bedbugs’ saliva can spread the infection to other areas of the body. If the bites are particularly itchy, you should seek medical attention.
Bedbugs can pierce the skin with their tiny proboscis. They are active at night, when humans are asleep, and most often do not feel the bites. Some people are extremely sensitive to the bites, but others do not have any reaction at all.
