The Bed Bug Life Cycle

You need to know what each stage of the bed bug life cycle looks like to tell if there are multiple generations in your home. A bed bug’s life cycle consists of three phases:


Bed bugs hatch from eggs that are grain-like and milky white. A female bed bug can produce from one to five eggs per day and may lay 200 to 250 eggs in its lifetime. Eggs are laid one at a time or in groups, deposited in nooks and crannies. Around one millimeter long, an egg is about the same size as two grains of salt. In six to ten days, bed bug eggs hatch, and the nymph bed bug seeks out its first meal to transition to the next phase.


Before reaching adulthood, these young bed bugs, also known as nymphs, go through five molts. Nymphs are tiny and have not reached sexual maturity despite their resemblance to adults. They start out with a yellow-white color but turn reddish-brown as they grow older. Every nymph needs a blood meal to finish the molting process. Five weeks after hatching, nymphs mature into adults if they grow at room temperature.

Bed bugs frequently feed every week and can reproduce once they reach adulthood. They are normally about a quarter of an inch in size. In the meantime while they are not feeding, bed bugs hide away where they can’t be easily found.

What Affects a Bed Bug’s Lifespan?

The lifespan of a single bed bug can range from a few months to a year. The length of a bed bug’s life is mainly determined by temperature and other external factors, the quality and accessibility of food, and heredity. A bed bug can typically live for six to twelve months in a controlled setting in places where other bed bugs hide.

However, a bed bug’s life in the actual world is considerably different and, on average, shorter. Competition with other bed bugs, exposure to hazardous chemicals, the possibility of being crushed while feeding, and predators and other risk factors are only some of the dangers faced by bed bugs in the vicinity of a person’s bed.

Here are some favorable conditions for where bed bugs hide:

  • In warm temperatures, bedbugs multiply more quickly. At 80°F, it takes about a month for an egg to become an egg-laying adult. At 64°F, it takes four months. This means that bed bugs in warmer regions can produce multiple generations in a year.
  • They need to have an abundant food source. Despite this, nymphs and adults can go without food for months at a time. The bed bug’s chances of surviving without a blood meal are higher at cooler temperatures. Nevertheless, they go into a semi-hibernating state if they don’t get enough food.
