You don’t expect to find roaches in the cabinet next to your coffee grinds when you wake up before the sun rises and go to make your coffee. Chances are, your reactions aren’t as sharp in your pre-caffeinated state, and your kitchen visitor will flee before you can find anything to smash it with. You would have claimed that you didn’t have any bug problems, especially roaches if someone had asked. But you also know that until it’s dark, you’re unlikely to see one of these animals.

Why Do Roaches Come Out At Night?

So, Why Do Roaches Come Out At Night? The short explanation is that roaches, like other nocturnal species, have evolved to scavenge for food and water in low-light areas to avoid predators. In this blog post, we will look more closely at cockroach activity patterns and offer advice on how to keep these pests out of your home.

Are Cockroaches Active at Night?

While there are many different varieties of roaches in Indiana, many of which are also found in Southern states as well, the majority of cockroaches that infest our houses are nocturnal. After the sun goes down, these pests emerge and feed on nearly any organic substance they can discover, including pet and human foods, as well as filthy clothing, leather, and book-binding glue. During the day, these pests hide in the smallest cracks and crevices in our homes, often going undetected until you have an infestation. When this occurs, you are more likely to see a roach during the day.


Most people believe that cockroaches flee because they are terrified of light, however, this is not the case. Let’s go over some of the other common concerns that homeowners have about these unannounced visitors.

Why Do Cockroaches Avoid Light?

Cockroaches are not afraid of light in the least. Cockroach species that have not been exposed to human predators have been shown to crawl toward the light. Even common house cockroaches have been observed gravitating towards, say, a lighted TV screen at night.

So, Why Do They Flee When You Turn On A Light?

Because they’ve discovered. They understand that light is turned on indicating that they have been detected by a human. And that discovery usually has bad effects. As a result, when you turn on a light, cockroaches do not flee into gaps and other hiding spots to avoid the light. Rather, nature has taught these species that if they don’t want to be killed, they must move quickly.

Cockroaches Do They Sleep?

Is there a period when roaches sleep if they are more active at night? There is, of course! Cockroaches, like most other creatures, have a circadian cycle. The circadian rhythm is a sleep-wake cycle in which active/wakeful and inactive/sleep periods alternate.


An animal is normally awake and actively hunting for food, mates, and water during the active/wakeful times of the day. The majority of cockroach pests found in homes are most active in the first few hours after the lights are turned off.

As a result, these few hours often feature the maximum amount of cockroach activity. These few hours are usually sufficient for the roaches to feed and mate. However, if you have a high-density infestation with a large cockroach population, these pests may be compelled to spend more time scavenging because food sources are more limited.


In other words, if you notice cockroaches in the early morning hours, you’ve got a bigger problem on your hands.

What Do Roaches Sleep Like?

Many scientists have attempted to understand more about how cockroaches sleep. According to one study, roaches have three stages of activity. Each phase is explained briefly below:


  • The first, movement, happens mainly at night when roaches are most active.


  • The second is a period in which just the antennae and limbs move, with no locomotion. Only the antennae and a few limbs move during this condition. The cockroach is otherwise motionless and inactive.


  • The third condition is total immobility, in which the cockroach does not move at all. In humans, this is analogous to sleep.


A cockroach spends most of the day in the second or third condition. It then becomes active and flips to the first state at night.

Do Cockroaches Enjoy Sleeping?

You’ve probably heard of individuals waking up with cockroaches in their ears. Even just thinking about it makes your skin crawl, doesn’t it? As a result, you may be concerned about roaches infiltrating your home while you’re most vulnerable—asleep in bed. This would almost drive you to call an Indianapolis exterminator right away!


It poses the question of whether cockroaches are drawn to our beds.


Quick response: No, thank goodness!


The fundamental motivation for a cockroach to emerge from its hiding location is the desire to feed. Cockroaches are unlikely to crawl onto your bed unless there are food detritus all over it. (Yet more reason to keep to your rule about avoiding eating in bed with the kids — and yourself!)


Cockroaches, on the other hand, are great climbers. They can readily climb nearly any portion of your bed—as long as it isn’t constructed of polished glass—so a roach can get up there. Furthermore, because roaches are nocturnal, they will most likely find their way onto your bed at night.

What is the source of those ear stories? Cockroaches, on the other hand, like small, warm, and humid environments. As a result, it is not difficult for a cockroach to enter your ear in quest of a safe resting or feeding spot.


While the possibility of this occurring is remote, it is a good reason to be wary of any cockroach infestation. You’re probably curious about how terrible your condition is now that you’ve seen a roach. Let’s look at several red flags that could suggest a roach infestation.

Cockroach Infestation Symptoms

While finding a cockroach is the most obvious symptom of an infestation, there are additional signs you may not have seen that roaches are infesting your home. Some indications that you have an infestation include:


  • An odd odor in the house
  • Cockroach droppings resembling coffee grounds
  • Cockroach “skins” shed by the insects
  • Casings for roach eggs


Cockroaches, as previously said, love humid, warm environments. As a result, the most typical breeding grounds for infestations are kitchens, bathrooms, laundry rooms, basements (if you have one), and drains. While these are the most prevalent problem areas, it is always best to get an expert to investigate for you. Finding the roach hotel on your own might be upsetting, and a novice may take much longer to identify a problem.

How to Prevent Cockroaches at Night

One of the most important things to remember is that even if you just notice one or two roaches, there are most likely many more that you aren’t seeing. Worse, cockroaches are active breeders who multiply quickly, which means you could soon have roach eggs all over your house. Unless sufficient control methods are implemented, these pests will quickly overtake your space.


So, what can a homeowner do to keep roaches out of their home at night (and other times)? Here are some pointers we frequently give homeowners dealing with an infestation on their own.

LIMIT Food and Water Access

  • Keep all food in insect-proof containers with tight-fitting lids or the refrigerator.
  • After using utensils, dishes, and pans, quickly clean them.
  • Clean up any food or drinks that have fallen or spilled onto counters, tables, sinks, floors, or other surfaces.
  • Before going to bed, wipe down all counters and remove any food particles.
  • Do not leave food or water in pet feeding bowls overnight.
  • Vacuum the floors to remove any remaining food debris.
  • Clean the areas beneath equipment, particularly toasters, refrigerators, microwave ovens, and stoves.
  • Keep your waste bins and containers clean, and dispose of garbage on daily pipes or faucets should be repaired.

Why Do Roaches Come Out At Night?


  • Clear away any unwanted clutter, such as newspapers, bags, corrugated cardboard boxes, and other items that tend to accumulate.
  • When storing objects, make sure there is enough space between them (using wire shelving can help with this).
  • Caulk should be used to seal off any crevices or cracks that could be home to cockroaches.
  • Seal areas where electrical wiring and pipes enter walls with steel wool or another abrasive material.


  • Keep firewood and debris heaps out of the way of the house.
  • Close your compost bin.
  • Lock trash can lids.
  • Cover vents with mesh.
  • Clear your yard of any fallen veggies and fruits.
  • Keep mulch and pine straw away from your house.
  • Install weather stripping on all of your home’s doors.
