Bed Bug Survival Without Food: Factors to Consider

Several factors determine how long Bed Bugs can survive without food. The first is the age of the worm.

The most obvious factor is the age of insects. The life cycle of Bed Bugs includes five stages from hatching to adulthood. Before molting and growing to the next stage of life, insects must eat at least once at each stage. If a Bed Bug does not eat for several weeks at each stage of its growth, it will die.

At every stage of life, they live longer without eating. Once they develop into full adulthood, they can survive for up to a year without eating. A study even showed that adult Bed Bugs can survive for 18 months without eating, as long as other living conditions are the best.

Another factor affecting their survival is their habitat and activity level. Bed Bugs that nest near beds or other furniture require less travel to find food. If insects don’t have to move too far, they can live longer without food. Insects that need to travel long distances to eat need more time.

Temperature is also important. In cold living conditions, Bed Bugs consume less energy and remain dormant. Under high temperatures, their bodies will consume more energy, and they must eat regularly to survive.

There was a detailed study on Bed Bugs in 2009. Entomologists have studied various Bed Bug nymphs, which are fed only once and allowed to develop to their first age. These bugs were not fed subsequently. There was a significant difference in survival time at different temperatures.

Researchers found that at 80 degrees Fahrenheit, the first adult stage of Bed Bugs lasts an average of 28 days. At a temperature of 98.6 degrees Celsius, bacteria can only survive for an average of 17 days.


Because they don’t eat organic garbage, dead skin, or leftover crumbs, bed bugs are different from other parasites. Unfortunately, these little, reddish-brown bugs only eat human blood.

They are capable of surviving even for a year without it. As they leave a red, painful welt after biting someone’s flesh, this resistance is not good.
