Bed bugs can go without feeding for 20 to 400 days, depending on temperature and humidity. Older stages of nymphs can survive longer without feeding than younger ones, and adults have survived without food for more than 400 days in the laboratory at low temperatures.
The bed bug life cycle starts with an egg. It is milky white in color, and about a millimeter long, resembling a grain of rice. Pregnant females lay three or four eggs per day (though sometimes as much as five), and up to 500 eggs can be laid in her lifetime. This high volume of eggs can allow a single pregnant bed bug to form a large
Egg-to-egg life cycle may take four to five weeks under favorable conditions. Living conditions: Bed bugs can survive and remain active at temperatures as low as 7°C (46°F), but they die when their body temperatures reaches 45°C (113°F).
An adult bed bug lives anywhere from four months to more than a year with the right conditions. Bed bugs can go an entire year without feeding, survive temperatures ranging between freezing and 122 degrees Fahrenheit and are constantly evolving, even adapting to resist standard insecticides.
A major problem in homes, businesses, schools, and transportation networks around the world, bed bugs have an active life cycle. They can live for up to a year (generally 6-12 months) depending on the conditions; the average lifespan is about 10 months.
Under normal circumstances adult bed bugs will live for about 2 to 4 months. Bed bugs need to feed at least once before each molt, although they could feed as often as once a day. Young nymphs can survive without a blood meal for days up to several months.
