How long does a bedbug grow?

Bedbugs typically take about 5 to 6 weeks to grow from an egg to an adult, depending on environmental conditions such as temperature and food availability. They undergo several molts during this process, needing a blood meal after each molt to develop further. Under optimal conditions, they can mature faster, while cooler temperatures or lack of food can slow their growth. Adult bedbugs can live several months to over a year, especially in favorable conditions.
