According to the Scientific America, a bed bug without a meal in warm temperatures, may survive 2 or 3 months and may only be deemed to survive longer (about a year) if temperatures are colder. How long can bed bugs live without air? According to the Atlantic Bedbug Inspection, suffocating bed bugs may work but when done right.
A Virginia Tech report shows well-fed adult bed bugs can live up to 300 days in the laboratory. Of course in a lab, they have access to food, live in steady temperatures, and don't get crushed. Studies in Europe done in the 1930s and 40s found they could live without food for over a year. This was in the UK before central heating was used.
Bed bugs can live approximately a year without feeding which is why they can thrive. The normal lifespan of a bed bug is 10 to 11 months.
Most bed bugs live for two to six months, though some can live for over a year without food by hibernating. Pregnant females lay three to five eggs per day, totaling up to 500 in her short lifetime. Pregnant females lay three to five eggs per day, totaling up to 500 in her short lifetime.
Adult bed bugs can survive for about five months without a blood meal. Once the bed bug settles on a host, it will feed for a few minutes. Length of feeding depends on the stage of development, how much it ate last time and how long it's been since it last fed. After the bed bug is full, it will leave the host and return to a crack or crevice, typically where other bed bugs are gathered.
