Can one bed bug multiply?
Compared 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.May 27, 2011
