🪳 Ever wondered why cockroaches shed their skin?
This image shows a cockroach shortly after **shedding its old skin — a process known as moulting**.
Unlike humans, cockroaches have an external skeleton called an exoskeleton. As they grow, this hard outer covering doesn't grow with them. Instead, the cockroach must shed it and develop a larger one.
🔎 What happens during moulting?
* The cockroach develops a new, soft exoskeleton underneath the old one.
* It splits and carefully emerges from its old skin.
* The newly moulted cockroach is often white or pale in colour and extremely vulnerable.
* Over the following hours, its new exoskeleton hardens and its normal darker colour develops.
* Cockroaches can moult **several times as they mature**, with the number depending on the species.
⚠️ So what does finding a pale cockroach mean?
If you see a pale, freshly moulted cockroach—or discarded cockroach skins—it's a good indication that cockroaches are actively breeding and developing nearby. Shed skins can often be found in cracks, cupboards, behind appliances, roof voids and other concealed areas.
