Although in a bed bugs ideal situation they would eat every five to ten days, this does not always happen. The exact amount of time a bed bug can live without a blood meal is still being debated in scientific circles. Current research leads people to believe that the average bed bug can survive in a home or office setting for approximately three months without feeding on human blood. There is some evidence that shows that because bed bugs are cold blooded animals, if the temperature in an area drops significantly they will go into a hibernation-like state and can therefore last up to a year without feeding.
