Understanding the Life Cycle of Bed Bugs to Better Fight Them

Bedbugs, by their Latin name *Cimex lectularius*, represent a major problem that can affect any home, both individual and collective. To be able to effectively combat them, it is essential to understand their life cycle. Indeed, in-depth knowledge of their development and behavior can help us detect their presence early, identify their favorite places and, thus, implement the most effective extermination actions.

The Life Cycle of Bed Bugs


Each bed bug life cycle begins with the laying of eggs. A female bed bug can lay between one and five eggs per day, usually in crevices and hidden places. These eggs, tiny in size (about 1mm long), are white and very difficult to spot with the naked eye.

Nymphs or Juvenile Stages

After an incubation period of six to ten days, the eggs hatch to release nymphs. These young bed bugs, also called juvenile stages, resemble adults but are smaller and lighter in color. They go through five stages of development before becoming adults, requiring a blood meal with each transformation. This process generally takes five weeks under favorable conditions, but can be prolonged in low temperatures or lack of food.

Adult Bed Bugs

Adult bed bugs are dark brown in color and measure approximately 5 to 7mm long. They feed on blood every few days, although they can survive for months without feeding if the opportunity does not present itself. Females begin laying eggs a few days after their first blood meal.

Fighting Bed Bugs at Every Stage of Their Life Cycle

For effective extermination, it is necessary to target bed bugs at each stage of their life cycle. Chemical and heat treatments can be used to eliminate both eggs, nymphs and adults.

The eggs are particularly resistant and can escape superficial treatments. This is why it is important to employ methods that penetrate the cracks and crevices where eggs are typically laid.

Nymphs, for their part, are often the preferred targets for treatments. They are more susceptible to pesticides and other extermination methods.

Finally, eliminating adults is essential to stop reproduction. However, the latter are also the most resistant and the most difficult to exterminate, due to their ability to hide in inaccessible places and fast for long periods of time.
