Most people don’t realize how long bed bugs live without food, but they actually can go for up to a year without food. Bed bugs are able to survive for so long because they can hold on to moisture. The humidity that they get from the host’s blood keeps them alive, so it’s no wonder that they can survive without food for so long. However, bed bugs can’t live forever without food because they’ll eventually dry out.
In the laboratory, bed bugs can survive without food for up to 400 days. Of course, they can only survive for so long if they are still young nymphs. Young nymphs cannot live without blood for a very long time, since they need it to molt and become adults. However, this doesn’t mean that adults can’t survive without food for longer.
Although a bed bug can live up to a year without food, they are more likely to survive for a few weeks. In the nymph stage, bed bugs will only survive a few weeks, but the later stages of bedbug development will live longer without food. Regardless of the length of time bed bugs can survive without food, they can spread quickly. If you’re experiencing bedbug problems, you should seek out professional help to get rid of the infestation as quickly as possible.
As mentioned, the temperature of a room can affect the length of time that bed bugs can live without food. In cold temperatures, the bugs will use less energy, while in warmer ones, they’ll use more energy to stay alive.
