Baby Bed Bugs (Nymphs) The first thing a newly hatched baby bed bug does is search for a blood meal. Baby bed bugs (technically called "nymphs") go through 5 stages of development instars. So a 1st instar nymph is a "newborn" and a 5th instar nymph is a "bedbug teen", so to speak.
One bed bug strain was highly susceptible to pyrethroid insecticides, the second was a highly resistant strain, and the third showed a declining level of resistance to pyrethroids. Cohort life tables were developed to study the survivorship and development of the immature stages of all three bed bug strains.
Bed bugs go through five stages before reaching adulthood. These five stages are known as Nymph stages as bed bugs do not have any larval stages of development. It can take up to four months of feeding and molting before the bed bug reaches adulthood.
Bed bugs go through several stages of life until they reach adulthood. First is the egg, which looks like a milky white grain of rice. After about two weeks, the eggs hatch and the nymphs emerge, ready to feed from day 1. The nymphs must go through five molting stages before they reach adulthood, and they cannot molt without a blood meal.
With the right conditions and temperatures, a bed bug can go from an egg to its adult stage in approximately 37 days. Warmer climates promote faster bed bug reproduction and development. Baby bed bugs are called nymphs. A nymph will go through five phases of growth before it becomes an adult, shedding its skin each time, according to the EPA
