I Saw One Cockroach. Should I Be Worried?

Cockroaches are said to be one of the most undesirable pests.

They’re easily spotted and can cause countless health problems. If you’re considering a pest control solution, read about signs that you might be seeing one around your home.

So, should I be worried if I saw one cockroach?

Many people worry that cockroaches are a sign of a bigger problem in their home or apartment.

However, this isn’t always the case. Though cockroaches are unsightly and gross, they generally don’t mean you have a pest problem in your home.

Before you panic and call an exterminator, you can check the signs of a cockroach infestation. Let’s dive into this problem now!

I Saw One Cockroach. Should I Be Worried?

If you observe a cockroach that is less then one inch long in your bathroom or kitchen, it’s highly unlikely that it’s a sign of a more dangerous pest problem in your home.

Seeing them is typically a sign of a small infestation that is common amongst homes with small crevices, or attics with poor ventilation.

If you observe one cockroach that is about one inch or more in length, it is a sign of a more serious problem.

They are mainly unintentional invaders that enter your home from outdoors or from neighboring apartments.

You’ll be surprised to find that cockroaches are nocturnal creatures.

Signs of a Roach Infestation

Bugs That Are Either Dead or Alive

Check the corners of your house for cockroaches.

You’re seeking for other roaches, dead or alive.

When attempting to get rid of a cockroach infestation, don’t forget to check the corners of your house.

Casings For Eggs

Cockroaches reproduce fast, therefore it’s critical to check all crevices and corners in your house when attempting to get rid of a cockroach infestation.

Roaches do not lay their eggs on wood surfaces or in cracks, but stick them to anything they can using glue secreted by their abdomens.

Instead, they produce what are called “oothecae” or egg cases or capsules, which are simply their hardened egg cases.

They are lengthy, narrow egg casingsthat are attached to whatever they can using glue secreted by their abdomens.

These instances are generally discovered among books, magazines, boxes, dishes, and drawers.


As they mature, baby cockroaches shed their skin a few times until they reach adulthood.

If you notice the light brown skin casks that are attached to walls or furniture in your home, that’s a sign that you have a cockroach infestation.


Cockroach feces are a brown color and have an unpleasant smell.

For starters, look behind different boxes and appliances.

Look for cockroach droppings behind the stove or cupboards and under small appliances like the toaster.

How Can I Tell If There Are More Cockroaches?

There Is an Unpleasant Odor.

Roaches are stinky creatures and in sufficient quantities, they can really smell bad.

The insects will regurgitate up their food several times so they can digest it properly.

Combine it with the oleic acid released when they defecate, and the smell becomes much stronger.

You may have detected a foul and unpleasant smell whenever you enter a kitchen or bathroom.

A cockroach infestation is likely taking place if there are droppings on countertops and in drawers or cabinets.

Cockroaches Can Be Seen During The Day

A cockroach seen during daytime means there are probably more around than you can see.

It’s one thing to catch a glimpse of a cockroach in the dead of night but it’s quite another to find them during the day.

However, seeing one cockroach openly strolling throughout the kitchen is by no means a sign that an infestation is taking place.

The bug is generally nocturnal, which means it’s active during the night.

Remember that cockroaches are nocturnal creatures and so you are most likely going to see them at nights.

They spend the day in dark, humid places like under the sink, in behind or inside appliances and in closets.

There Are Several Body Parts

In addition to egg shells, the bodies of these insects are made up of several body parts.

There are several reasons you might need to hire a pest control company to take on your home’s pest problem.

When cockroaches die, other cockroaches will sense it and will eat the body’s remains.

Roaches just cannot ignore decaying food and they are more likely to invade a home with piles of pet food or food waste lying around.

You Find Evidence Of A Growing Colony

Roaches do not respond to sound, but respond to touch and movement.

They make egg shells, known as exuviae, that help them hold onto surfaces as they move from one place to another.

Some species’ casings may carry microbes and bacteria that can cause serious human diseases.

Finding one of these shells does not indicate an infestation, but finding several does mean that you have an infestation on your hands that requires immediate professional attention.

Search for Droppings

If you can’t locate any adult roaches, or if you find live roaches in only one or two rooms in your house, you should check the places where you have seen signs of cockroaches in the past.

Roach dung is dark brown or black and may be found in small amounts on dark surfaces near areas where you find adult roaches and feces.

However, if you know what signs of cockroaches to look for, you’ll have a better chance of keeping your home roach-free.

Roaches that are clustered together in a corner or hiding beneath a piece of furniture are a sign of a cockroach infestation.

The waste is often black or brown and is mixed with bits of food and feces.

Some droppings contain more moisture than others and may have a greasy or waxy appearance.

Examine Common Hiding Places

Sitting idly by and waiting is no longer an option if you don’t want an infestation of cockroaches in your home.

It is preferable to be scientifically informed than to be credulous about pest control measures.

These insects are elusive, preferring to lurk in dark, secluded places until they’ve found food for their young or a source of moisture for themselves.

They are nocturnal and retreat into cracks and crevices at night when the temperature drops.

As a consequence, most cockroaches that invade homes do so in the numbers that will soon cause an infestation.

Roaches, in general, like warm, humid places to survive and breed.

The kitchen and bathrooms are a common breeding ground for roaches and these areas should be well cleaned on a regular basis in order to remove the moisture and food sources that attract roaches in the first place.

What Should You Do If You See a Cockroach?

Identify the Type of Cockroaches

Based on its look, you may find that you have a German cockroach in your home.

Smaller than 1 inch indicates an immature German cockroach.

German Cockroaches and Brown Banded Cockroaches Both species have similar body shapes, but their gross anatomy differs slightly.

Both of these species are very omnivorous and feed on almost anything that comes their way.

They stink, look absolutely disgusting and contaminate surfaces with their droppings.

By swiftly, I mean it will still take at least an hour for you to deal with a cockroach infestation if you do it yourself.

Inspect Your House for an Infestation

A few additional cockroaches that escaped have left you feeling uneasy, and there is a chance of an infestation.

The infestation may be in its early stages, or you may have been invaded by a massive number of cockroaches.

The procedure for dealing with them depends on their type and the stage of their infestation.

How to Prevent Cockroach Development In Your House

The first step in getting rid of a cockroach infestation is to determine their initial points of origin.

A cockroach may enter your house through a variety of ways; maybe it goes through the window frame or door, or maybe it wandered into your house through a crack.

  • Using drain pipes into the sink to run a tap for a few seconds and leave your doors open.
  • From the outside, via light or wall cracks, and from inside through cupboards and bags for example, via sanitary products if not sealed.
  • Fill up the gaps with sealant and wait for them to come out on their own.
  • With used or wet papers or food containers that you throw into the garbage.
  • Check any used oil or grease cans and wipe them off, to prevent the roaches from breeding in them.
  • You had them tied to a hook in a wall or behind a radiator, or they jumped around in a bathtub.

Be cautious the further out you go the bigger the chances of finding these pests.

Cockroahes are being social insects, which means that they find it easier to live in groups or colonies.

Cockroaches are infiltrating via light or wall cracks.

Fill up the gaps with sealant and wait for them to come out on their own.

The second step is to use the right cleaning products to eliminate them and prevent them from coming back.

If you see any signs that you have cockroaches, take action immediately.
