Do Cockroaches Sleep?

Cockroaches sleep: Fact

Cockroaches are nocturnal creatures often appearing in the dead of night in search of food, water and a possible mate. With burning all this midnight oil, do cockroaches ever get a chance to grab some “shut eye?” Let’s find out in this month’s fact or fake.

With the constant hustle and bustle of “working the night shift” in the search for food, cockroaches are bound to get tired and need rest. The nocturnal pest does need its rest, and they do “sleep,” just not in the sense of closing their eyes and hopping underneath the covers. While cockroaches have eyes, they don’t have eyelids to shut them and sleep as humans do. Instead, most species of cockroach operate with specific circadian rhythms of activity (like almost all living creatures).

During the daytime hours, cockroaches will become inactive (or “sleep”) in preparation for their big night out. Finding a dark place to rest up during the day, cockroaches enter a state of immobility as if they’re playing dead. This period of paralysis is the cockroach’s equivalent to sleep. If left undisturbed, they’ll wait about four hours or so after the lights go out before they make their emergence into the nightlife. In areas with a highly concentrated cockroach population, you may see them scurrying around during the day in search of food to beat out the competition that only searches in the wee hours of the night.

No matter whether you’re dealing with sleeping or active cockroaches, leave the treatment to the professionals. Contact your local Orkin professional to schedule an inspection and customize a plan that’s right for you.
