Cockroaches are one of the most resilient and widespread pests in the world. They can quickly take over houses, breeding quickly and hiding in crevices while they eat and lay eggs. But what do those eggs actually look like? In this article, we will describe the size and color of cockroach eggs, how they are laid, and how to identify them during an infestation.

What Cockroach Eggs Look Like

Appearance

Cockroach eggs are small, about 0.9mm to 1.3mm in length, and are yellow to orange in color when first laid. They usually come in a capsule-like capsule made out of a protein substance called chitin, or in clusters of egg cases, called Ootheca. The capsule usually contains between 10-50 eggs and can be up to 1cm long.

Ootheca

The egg cases, or ootheca, come in various shapes, depending on the species of cockroach. The most common is that of the German cockroach, which is a brown, oval-shaped capsule with a raised pattern on it. Other species of cockroaches such as the American and Oriental cockroaches have ootheca that are dark brown or black and either flat or slightly domed.

Lifespan

Cockroach eggs can take anywhere from several weeks to several months to incubate and hatch, depending on the species. The American cockroaches have a longer incubation period than the German cockroaches. Once hatched, the nymphs, or baby cockroaches, will take approximately two years to reach adulthood.
