All cockroach species go through three distinct stages in their life cycle: egg, nymph, and adult. Female cockroaches lay egg cases or sacks known as ootheca which can hold multiple eggs inside. The number of eggs per ootheca varies depending on the species.
Although it's not as common as finding live cockroaches that roam around your property, finding cockroach eggs is the strong indication that you have a cockroach infestation. Nevertheless, the correct cockroach eggs identification remains important to get to know which cockroach species you are currently dealing with.

Since each cockroach species has different physiological and biological ways of reproducing, thus the cockroach egg size, colours and appearance will look different depending on the species.
The German cockroach (Blattella germanica) is the most common cockroach species found throughout the world, and able to live near humans.
Their eggs have a typical tiny, brown, and purse-shaped capsule egg case with 8 mm approximately long. The female German cockroaches can produce between 20 - 40 eggs in a single ootheca.
The American cockroach (Periplaneta americana) are widely distributed around the world and mainly lives in tropical and subtropical areas. Their eggs are dark brown in colour, and roughly 38 mm long in size. A female American cockroach lay 14 - 16 eggs in a single ootheca.
One thing that distinguishes this type of cockroach with the other is the ability of a female American cockroach to mate once to produce multiple oothecae since they can store the sperm on their organs.
The Australian cockroaches (Periplaneta australasiae) are quite similar to American cockroaches - except their body is smaller and darker. Their eggs are about 9 mm in length and are reddish-brown in colour. A female Australian cockroach can produce about 22 - 24 eggs in a single ootheca during her lifetime.
