Question: What kind of roaches are white in color?
ANSWER: Actually, there are no white cockroaches.
What you found was a cockroach that had just shed its skin (molted) in the process of growing larger or advancing to the adult stage. In the process of shedding the old skin, the new skin appears white. It takes about 6 hrs for the new skin to ”tan” (a chemical process) and become hard and brown; then the cockroach will look like all the others in the population.
If you are seeing “white” roaches, you have a rather extensive problem. You have a mature population, and the time for action is now!
