Occasionally, people may pick up bed bugs in theaters or on buses and trains. People can also bring bed bugs into their home on infested clothing, bedding, furniture, and luggage. Bed bugs can go without feeding for 20 to 400 days, depending on temperature and humidity.
Although bed bugs can live for over a year without feeding, they typically seek blood every five to ten days. The only way to know for sure what bit you is to find a bug and get it identified. Bed bugs live off only blood—like mosquitoes do.
Scientists debate this point, but evidence suggests that at normal room temperature, about 23 degrees Celsius, bedbugs can only survive two to three months without a blood meal.
Bed bugs can go without feeding for 20 to 400 days, depending on temperature humidity and other environmental conditions. Bed bug adults can only survive about three to five months without a blood meal if they occupy an environment that resembles normal room temperature and relative humidity.
A bed bug can take six times its weight in human blood during a nighttime feeding, and feeding can take 3 to 10 minutes. How long can bed bugs survive without a blood meal? It's not as easy as you would think to starve these little guys out by, say, just leaving your home for a couple of weeks.
Depending on the temperature, it takes nymphs about 100 days for the five molts to occur before mating can take place. Roughly 1.5-2 months are required for a complete cycle from egg to mated adult bed bug. Adult bed bugs live about 10 months, although without a host, bed bugs may live over a year. Bed bug infestations develop slowly.
