How long does pregnancy lasts in cockroach?

Answer 1

Baby cockroaches may appear in anywhere from 24-300 days. The exact number of days depends upon the particular cockroach species. The time from the laying of the eggs to the emerging of the babies properly is called cockroach 'gestation'.

Specifically, the female takes two days in which to create an egg case and fill it with eggs. With most cockroaches, the case will be put somewhere the mother-to-be considers safe. It's only in a few species, such as with the German cockroach [Blattella germanica], that the female keeps the case on her body, attached to the abdomen.

The colors and lengths of the cases vary with the species. For example, the American cockroach [Periplaneta americana] makes a dark brown case that's about 1/3 inches long. American cockroach babies hatch in 24-38 days.

The brown banded [Supella longipalpa] cockroach makes a light red brown case that's about 1/4 inches long. Brown banded cockroach babies hatch in about 70 days.

The German cockroach [Blattella germanica] makes a brown case that's no more than 1/2 inches long. German cockroach babies hatch in about a month.

The Oriental cockroach [Blatta orientalis] makes a dark red brown base that's about 1/2 inches long. Oriental cockroach babies hatch in about 300 days.
