I saw one Cockroach Should I be Worried?

Cities worldwide, including the US, are getting congested, making it easy for roaches to infest homes. Asthma and Allergy Foundation of America(AFFA) reported that almost 63% of houses contain cockroaches and their parts.

Therefore, some of us might anxiously be asking, I saw one cockroach should I be worried?

The answer to this question is a little tricky. You should do the following if you see a cockroach:

If the one cockroach you saw is a small cockroach, smaller than a dime, you should be worried.

If it’s a large cockroach, then you can relax as they do not infest homes so easily. If you saw a baby roach, you are already in trouble.

Also, make sure you are not confusing another bug for a cockroach.

Seeing Small Roaches

Small cockroaches are extremely capable of infestation. Furthermore, these roaches reproduce astonishingly fast. For example, a female German cockroach produces about 360 baby roaches in her lifetime.

If you have seen a cockroach that measures less than an inch, your house is most likely infested or will be sooner.

Once the small roaches enter the house, they nest at difficult places to reach and reproduce, quickly turning your place into a roach breeding hub.

Furthermore, the exoskeleton from a molting nymph, the poop, and saliva from small roaches can trigger allergies and asthma episodes. They can also transfer bacteria, including Salmonella Typhi, from sewage to your food.

Therefore, seeing a small roach at your place should not be taken lightly.

Seeing Big Roaches

In the United States, especially in Florida, any cockroach that measures greater than 1 inch is also referred to as the Palmetto Bug.

Bigger roaches may seem very dangerous, but the good thing about them is that they are least capable of infestation.

Big roaches are, most of the time, accidental intruders. They are usually brought inside the house accidentally, along with different items like Exotic Green plants, firewood, etc.

An infestation with big roaches is less likely, and exterminating them is easy compared to small roaches.

Therefore, seeing a big roach greater than 1 inch in size should not make you worry. But this does not mean that you should take them lightly.

Instead, you should also exterminate big roaches; otherwise, rarely, they can also cause a full-blown infestation.

Do you know that some of the biggest cockroaches, like one found by a Facebook user Locutor O. Paniagua on September 4, 2020, measured 4.5 inches, holding a world record?

Does one cockroach mean an infestation?

Seeing one cockroach might give you goosebumps, but it does not necessarily mean that you have an infestation.

If you have seen a 1 small cockroach measuring less than an inch, it is most likely a German, Oriental, or American cockroach. Seeing them is usually a sign of infestation.

On the other hand, if you have seen 1 cockroach measuring greater than an inch, you probably saw a palmetto bug. They are usually accidental intruders and mostly have nothing got with an infestation.

You will also be amazed to learn that roaches sleep in the day and look for food at night.

What to do if you see a cockroach?

Follow these steps after you saw one cockroach. Additionally, it’s better to get a little worried than before things are out of control.

Step 1: Identify the type

Identify the type of cockroach based on its appearance and size. Smaller than 1 inch most likely means an infestation, greater than 1 inch means accidental intrusion.

The smaller cockroaches are mainly either German Cockroaches or Brown Banded Roaches.

Both of these species are highly invasive and are very hard to eliminate if you don’t take them seriously. They smell bad, look bad and grow very rapidly.

By rapidly, I mean it will still take 3-6 months before the population explodes, but that is fast in the cockroach world.

Also note that all small cockroaches are not invasive like the wood cockroach, Asian cockroach, etc.

The larger cockroaches like American Roach, Florida Wood Roach, Smoky Brown Roach, Australian Roach, Oriental Roach, etc, can infest homes in ideal conditions, but normally they can end up in your home from the outdoors, and you don’t need to worry about them.

You better watch your drains and close any gaps and crevices to avoid them getting in. Check these top five anti-cockroach drain covers.

Step 2: Inspect your home for an infestation

Checking your home to conclude an infestation is a lengthy process that I am not going to completely explain here but you can check this blog post for it.

In summary, you need to properly check your entire home for all signs of infestation.

The top signs are:

  • More cockroaches
  • Cockroach eggs
  • Shreded skins
  • Baby cockroaches
  • Smear Marks
  • Cockroach poop
  • An ideal condition for roaches to grow and bread

Finding a few more cockroaches is a CONFIRMED sign of infestation. The level of infestation can be in the early stage, but you are confirmed infested and need to work quickly in getting rid of them.

Regardless whatever level of infestation it is, the process to take of them is the same.

Step 3: Taking all steps to avoid cockroach growth

Now the last step is to make sure you don’t see any more cockroach in your house.

The first step to getting rid of a cockroach is to remove the source of the cockroach.

A cockroach can end up in your home via following ways:

  • Via drain pipes. Get your self a drain cover to stop them.
  • From outdoos via gap under doors windowns etc. Reduce the gaps or use foam pads to stop them.
  • With used or old furniture. Make sure to check any used item you recently bought.
  • You brought them from somewhere else attached to your cloths or luguagge. Be craeful next time.
  • Cockroahes are coming from neighbours. Check this article for that.
  • Cockroaches are invading via gaps left for shared plumbing lines. Close those gaps via Loctite Foam Sealent

The second step is to use a gel bait to make sure the cockroaches does not survive. Follow this step if you observe some degree of infestation.

Get this Advion Gel Bait and apply as per instructions on the pack.

The third step is to use an IGR (Insect growth regulator) to stop baby cockroaches from becoming adults.

Get this Gentrol Insect Growth Regulator for this purpose. Use according to instructions on pack.

Does having roaches mean your house is dirty?

Having roaches in your house does not necessarily mean that your house is dirty.

Cockroaches are attracted to many things including poor lightning, high humidity, good hiding places, and heat from electric appliances.

Besides these, many of the times roaches are accidental intruders and the level of cleanliness has nothing to do with a roach infestation.

For example, roaches can be accidentally carried along with firewood, furniture, groceries, etc.
