After four to five weeks, the newly-hatched bed bugs are old enough to start laying eggs themselves. After the infestation reaches this point, it can begin to grow exponentially.
How quickly do bed bugs lay eggs?
Female bed bugs typically lay an average of one egg per day, although they can lay as many as 5-7 eggs in a single day at their peak. It takes only 10-15 days for an egg to hatch, and a bed bug is able to reproduce about 6 weeks after hatching. And most bed bugs live approximately 4-6 months.How long does it take for a bed bug to reproduce?
Myth 2: Bedbugs reproduce quicklyCompared with other insects, bedbugs are slow to reproduce: Each adult female produces about one egg per day; a common housefly lays 500 eggs over three to four days. Each bedbug egg takes 10 days to hatch and another five to six weeks for the offspring to develop into an adult.
