Cockroaches lay eggs in egg cases that are made of a protein substance produced by the female cockroach. This substance hardens over time to protect the eggs from predators and the elements. The number of eggs in one egg case varies by species. Some roaches lay as many as 50 eggs. American cockroaches typically lay from twelve to sixteen eggs in one case.
The average life span of a cockroach is about 100 days to one year. A female German cockroach can live for over 200 days. A female American cockroach can live up to a year. A cockroach egg is around 8 millimeters long and turns black in a matter of days.
Cockroach eggs are not easy to find. Most cockroach species lay their eggs in a safe place. In fact, some species carry their eggs around until hatching. However, if you’re looking for an egg case, you might want to check the area where the cockroach lays her eggs so you can make sure that they’re safe.
Cockroach eggs come in various shapes and sizes, with most measuring between half an inch and a quarter inch in length. The egg case of an American cockroach is three to eight millimeters long and is slightly puckered at one edge. In addition to their shape, cockroach eggs are also different from other roach species. For example, American cockroach eggs are brown when they’re young. They’re also about 8 millimeters tall and five millimeters wide.
