Why is a Cockroach White?

If you’re wondering why a cockroach is white, you’re not alone. It’s not uncommon for any roach to go through a white molting stage, known as an instar. In fact, a mature cockroach may go through this stage multiple times. But white cockroaches are more common than you might think, and it’s not because they’re albino.

Cockroaches that appear white are normal and rarely harmful, since they hide very well. During the molting process, cockroaches become vulnerable to predators. Their molted bodies are not rigid enough for them to move, so they tend to stay hidden in tight places. During this period, they won’t venture out again until their molting cycle has finished.

Before molting, cockroaches need to form a new outer shell. This new skin keeps their body parts together and helps retain body moisture during the process. At first, the new skin is very soft, but lacks pigmentation, which gives the shell color. When the roach is ready to molt, they split open the old skin, which is why they appear white.

Once you find the roach, it’s best to check other areas of your home for more of them. A white cockroach will be most likely to come from a deep corner of your home, so you’ll want to look for any gaps and crevices that could harbor the insects.
