Molting

Cockroaches go through seven to eight molts before reaching adulthood. The process involves shedding a shell and then growing a new one to suit their larger size. They continue growing and shedding until mature.

The number of molts a nymph undergoes varies by species. With each progressive molt, nymphs appear to look more and more like its adult counterparts.

When these pests outgrow their exterior casing, known as the cuticle, they split the cuticle and shed it. Their soft skin beneath appears white. Within a few hours, their new cuticles will harden and darken, appearing more like the typical coloration of its species.

Encounters & Concerns

Cockroach infestations can lead to the spread of disease and can even trigger asthma. Their presence in homes are a problem because it suggests breeding adults are also in the area.

For some species, their molted exterior serves as a food source for both nymph and adult roaches.
