Bedbug infestation is an extremely common problem worldwide.

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. Bedbugs can cause health issues such as skin rashes, allergies, and psychological effects.

Bedbugs can be detected with CO2 gas or a bucket of dry ice to lure the bedbugs to come out of hiding. Usually they are hard to find but infestation can be determined after being bitten or by finding fecal matter, molts and blood smears on the linens. Usually, bedbug bites do not appear right away but takes a week before red welts show up. The most common style of bedbug bites come in a line of three, also known as “breakfast, lunch and dinner” (Bed Bug Bites Symptoms).

Earlier we stated that bedbugs are attracted to CO2; however, high concentrations of CO2 will kill them. If bedbugs are discovered, get an exterminator that uses cryonite to spray down the surface and cracks. Cryonite is a compressed CO2 snow that is non-toxic but kills many pests by freezing them. When CO2 snow hits the surface at normal temperature, it evaporates and turns into CO2 gas. CO2 is poisonous to humans at high concentrations; therefore, if a fixed CO2 detector is not installed, using a handheld CO2 monitor while using cryonite is a good idea.

Based on the National Institute for Occupational Safety and Health (NIOSH) Pocket Guide to Chemical Hazards, common symptoms of CO2 exposure include dizziness, headache, poor sleep, lassitude, anxiety, ocular changes, coronary heart disease, gastritis, kidney and liver damage, eye and skin burns, and dermatitis. These symptoms will occur only if the NIOSH standard’s recommended exposure limit (REL) and / or Occupational Safety & Health Administration (OSHA) standard’s permissible exposure limit (PEL) exceed 5,000 ppm.
