Cockroach nymphs are tiny insects that are born from a female cockroach. The female cockroach ootheca is reddish brown in color and measures five millimeters long. The nymph will lay around 16 eggs in its case. The nymph will live for three to six months before developing into an adult.
Cockroaches reproduce rapidly in water and food rich environments. Just one nymph laying an egg can cause a large infestation. Therefore, it is important to try to control the population as much as possible. There are a number of different ways to do this.
Female cockroaches lay eggs in an egg case. These egg cases are found in the female genital chamber and posterior end. The egg case holds 30 to forty eggs, and is about 8 millimeters long, three millimeters high, and two millimeters wide.
American cockroaches lay their eggs in egg capsules. These egg cases are small and brown. The female roach will carry these capsules for up to two days before depositing their eggs. The eggs hatch in about 24 to 38 days. The American cockroach will lay up to six or seven cases throughout its life.
Once the nymph reaches this stage, it will enter the adult stage. Then, it will reproduce and begin the cycle over again. Cockroaches are relatively long-lived, so it is important to control cockroaches as soon as possible.
