Why do cockroaches turn over when they die?

Question: I have noticed that when a cockroach dies, it first turns over on its back. Can you please tell me why cockroaches do this?

ANSWER: It depends on what the roach was exposed to. Many (but not all) of the modern insecticides cause this. It may be due to the effect on the nervous system of the roach. The roach goes into spasms which will cause it to flip on its back. This is very apparent when contact insecticides, which are normally available over the counter, are used.

Having cockroach issues? It is not controlled with insecticides only. Call your local Orkin branch office. An Orkin Pest Specialist will assess your situation and develop a customized, scientific and multifaceted treatment plan to help you control cockroaches and many other pests.
