The Shocking Truth About Roach Eggs You Never Knew! When it comes to household pests, few insects strike fear—or fascination—quite like the German cockroach. Among their most infamous and overlooked features are their eggs—commonly known as roach eggs or more technically, oothecae (singular: ootheca).
