Bedbugs are parasitic insects that feed on human blood. They can bite the face, arms, hands, and other exposed parts of the body while you sleep. These creatures are reddish brown in color and can live for months without a blood meal. This is the most common place where bedbugs bite.
Bedbugs live in beds and feed by drawing in warmth from their host. They seek out warmth because of their ability to smell human body heat and carbon dioxide. The CDC notes that bedbugs are most attracted to heat, so they will often remain within eight feet of a human host. However, they have been known to travel as far as 100 feet to obtain a blood meal.
Bedbug bites can cause severe itching. The bug’s saliva causes a reaction in the human body known as histamine. Depending on the severity of the reaction, some people may experience itching, blistering, and hives. In such cases, it is advisable to consult a doctor. Bedbugs can spread from one house to another by carrying on clothing, luggage, furniture, and boxes. They also easily hop from one floor to the next. While bedbugs do not cause serious health problems, they do have a high risk of spreading.
If you are convinced that you have bed bugs, you need to inspect your bed for signs of infestation. In addition to their excrement, bedbug pheromones can produce a foul, rusty odor. These smells can be particularly strong when an infestation has grown.
