The Roach Life Cycle

All roaches undergo a complete life cycle which consists of 3 distinct stages: egg, nymph, and the adult.

  1. Egg Production

The roach life cycle starts with the egg production. Eggs are produced by female adults who range from ten to forty eggs and they usually carry them in cases known as ootheca. Roaches eggs normally hatch within a period of twenty to sixty days depending on the type of roaches. This ootheca is carried by the female roach or if not carried, it is placed in a strategic location until it hatches.

  1. Nymph to Adult

The newly hatched roaches come out of the egg as nymphs. The nymph, then, starts to grow by shedding the skin many times until the time it reaches adulthood. This process is therefore referred to as molting.

  1. After Molting

After the roaches undergo the molting process, they become a self –bodied and white in color. They, however, become larger, get darker in color and later harden off.
