If you’re concerned that you may have bedbugs, you should look for bite marks and blood stains on your sheets. These signs indicate that your bed is infested. Bed bugs usually bite on exposed parts of the body during sleep. The bites are clustered or line-shaped, and may be itchy and inflamed.
In severe cases, bedbug bites can cause an allergic reaction. In some cases, this allergic reaction can be systemic, and can cause serious respiratory or cardiac symptoms. However, this reaction is extremely rare. If you do experience an allergic reaction, it’s best to seek medical attention right away. If you have a severe allergic reaction, you may experience a severe rashes, hives, or welts.
Bedbugs may also bite the back of your neck. Because they hide behind things, you may not notice their bites unless you’re looking closely. Infestations can be hard to identify unless you’re a trained professional. The most effective way to distinguish bedbugs from other types of insect bites is by looking for bite marks. While bedbug bite marks can look similar to other insect bites, you should be able to tell them apart by their distinct redness and large tears. To confirm a bed bug infestation, you may need to have an expert perform a “biting edge debridement,” which removes the outer layers of skin. Usually, this will reveal a tiny amount of blood.
In some severe cases, bedbug bites can cause fatal illness. They can affect the heart, digestive, and nervous systems. In addition, they may aggravate respiratory conditions, allergies, and asthma. The high levels of histamine released by bedbugs can exacerbate these conditions. People who work night shifts can be particularly vulnerable to these infestations.
