Bedbugs are small, nocturnal parasites that feed off of warm blooded animals and humans. They can survive in a wide range of temperature, low humidity and live for a year without eating. Adults can measure up to 5 mm in length and up to 3 mm wide. They are attracted to carbon dioxide (CO₂) levels in human respiration and body warmth.
