The question “do bed bugs hold their breath?” may seem confusing. In reality, bed bugs do not hold their breath, but instead they use a complex system of tiny tubes, called tracheae, to obtain oxygen. These tubes are connected to big veins and arteries, and they branch off into smaller tubes as needed. This system also includes tiny capillaries.
If you have a bed bug infestation, you will have to deal with them during the night, when they are most active. Bed bugs will try to find a human or pet to feed on. This is because their carbon dioxide-rich breath makes them hungry. Keeping a room well-lit all night is very important to prevent infestation. Moreover, bed bugs will bite exposed parts of the body, but will avoid the head.
In addition to bite the human body, bed bugs may bite hair. In general, they prefer to feed on bare skin and neck. If you are looking for signs of infestation, you can check for intensely itchy welts along the hairline. You may also notice small drops of blood on your pillow.
Bed bugs have modified mouthparts that feed on blood. They do not have wings, and so they must crawl to move around. They can crawl through floor openings, walls, and ceilings. In addition, they can live on furniture and regularly moved objects. These bugs can be difficult to remove, but you can follow some simple steps to eliminate them.
