Can Roaches Drown?

Are you trying to kill roaches by turning on your tap to drown roaches with water, and you are wondering, can roaches drown?

Water is not an effective method for eliminating roaches. They can’t swim, but they won’t drown either because they can hold their breath for up to 40 minutes when not swimming.

They achieve this buoyancy by sealing their spiracles. Time to flee is a bonus, as is the ability to bob to the surface for air.

For your convenience, we’ve compiled the answer to the query can roaches drown? Read on to get the full details.


Do Roaches like Water?


Before we get to the question can roaches drown? Let us know if at all roaches like water. You might think that roaches don’t enjoy a quick dip in the pool.

That holds true for the vast majority of animal species, especially the common cockroach. The two most frequent species of cockroaches in homes, the German cockroach and the American cockroach, really dislike water.

They can maintain their hydration and moisture levels with merely the help of moisture and water. Water is a common source of enjoyment for Oriental cockroaches.

They populate areas with easy access to water, including flooded basements. They will look for standing water in your home, such as in the bathroom or near the foundation.

They tend to congregate near water sources in the natural, such as lakes and streams. Because of their affinity for water, these insects have another name: water bugs.

Even yet, oriental roaches have a limited ability to hold their breath. Neither of these is a natural swimmer, and you won’t see them lounging on a beach towel because it’s so hot outside.

You have gotten to know if roaches like water, let us look at our query, can roaches drown?

Is it Possible For Roaches to Drown?

Can Roaches Drown

Read on to know your query can roaches drown? Roaches are susceptible to the effects of water and can perish there.

They will drown if they are completely submerged in water and unable to come up for air, just like any other air-breathing organism.

They’re surrounded by water, but they don’t have gills or any other organs that would allow them to breathe the oxygen in the water.

A roach, however, will not be so simple to drown. In the wild, you won’t come across many cases of unintentional drowning. In particular, there are three reasons for this:


Holding Their Breathe

Cockroaches can float thanks to their full-body lungs, which they also employ to hold their air.

They have remarkable endurance for this kind of activity. A roach may go up to 30 minutes without breathing if it is completely submerged.

When sucked into a pipe, for example, this provides the roach with a perfect opportunity to Bob up to the surface.

Evacuate yourself from a flooded area by scrambling across wet surfaces. They must patiently wait for a human who has dunked or submerged them to emerge.

Roaches are also adept at pretending to be dead. There’s a chance that they’re just holding their breath under the water, making it look like they’re sick. They will hold off until they see a way out, and then quickly make their way to safety.

The Respiratory Spiral Diagram

The Respiratory Spiral Diagram of Roaches

Roaches are unusual among animals in that they do not use their lungs to breathe. The spiracle is their mode of breathing instead. In actuality, a roach’s body is covered with a series of holes and compartments.

These are like valves in that they open and close to let air in and out. A cockroach’s breathing mechanism looks like this. It can do this with or without its head above water.

The roach can breathe without opening its mouth. To further increase its resilience, a roach also breathes in short bursts.

In times of peril, cockroaches are able to plug these cracks. If they’ve been sprayed with poison and don’t want to breathe it in, for instance.

Roaches have a unique adaptation that allows them to survive in water by sealing off their respiratory system.

Cockroaches are able to float because the air they swallow is trapped inside. If you’re determined to drown a roach, you’ll find that doing so is a challenge.

Unless the roach has suffered an injury, such as a crack in its exoskeleton, it will continue to bobble. Because of the damage to its body and spiracle respiratory system, water will be able to enter.


Exceptional Climbing Capability

Glass and other perfectly smooth surfaces are too difficult for roaches to scale. They may have difficulty ascending the inside of your toilet bowl, just like any other creature would.

Roaches may not look like they can climb, but they actually have a remarkable capacity to do so. Take, for example, a bug that accidentally ends itself in a pail of water.

Somewhere in the bucket, it’ll probably get a grip. Therefore, it may safely crawl back out again. Putting a roach in a glass of water and hoping it drowns is a futile endeavor.

Could Cockroaches Swim Underwater?

Technically speaking, roaches are not good swimmers. Some animals even have a basic understanding of how to get around underwater.

Cockroaches from Asia, for instance, are more aquatically inclined than their American counterparts.

But this navigating is largely incidental. The cockroach may float because the air inside its body has been trapped when it has closed off its spiracles.

Now, it will rise to the top of any body of water on its own. In its frantic flight, a roach will undoubtedly paddle its legs.

The edge of a buck or the drain opening can be more easily reached with this method of guidance.

It may be able to paddle around underwater, albeit with impeded movement.

This is not effective conduct, and it is not deliberate. It is therefore neither floating nor submerged.

There are primarily two causes for this:


Unreliable Senses

It is a common misconception that cockroaches can survive in damp environments. They were never taught how to swim or use water navigation skills, thus they have none.

A cockroach may choose to stop moving altogether if submerged in water. It can’t swim because it can’t coordinate its leg paddles to propel it in the desired direction.

Instead, each leg of the mad scramble will activate at a separate time. This may alter its course to the point where it makes no forward movement at all.


Wrong Legs

Cockroach legs are so flexible that the insects can easily climb walls, ceilings, and furniture. Unfortunately, the body type isn’t optimal for swimming.

In spite of how hard it paddles, a cockroach can’t move because its legs create too much resistance. A roach is likely to spin in circles, unable to do anything about its predicament.

How Long Can They Go Without Breathing?

Oxygen is essential for cockroach survival. Without air, they will perish. You might think that drowning in a cockroach will solve the problem.

Roaches can hold their breath for long periods of time. Roaches, in contrast to people, can take breaths from any opening on their body, not only their throats.

Moreover, they may effectively seal off their spiracles. However, there is a catch to this. Depending on the species, roaches have varying breath-hold times.

All rely on the availability of oxygen. Underwater, a roach will be unable to breathe because it will be cut off from the air supply.

No amount of what is already in the water will be sufficient.

However, cockroaches cannot absorb this water because they lack gills. A cockroach doesn’t stand a chance in this place; they all perish within 30 minutes.

However, a roach can live for much longer if it is placed in an airtight plastic bag. Due to the fact that plastic bags aren’t completely airtight, this can take up to 40 minutes.

If the roach is lucky, some oxygen will make its way through the plastic and help it survive.



Going through this article, we gave you a satisfying answer to your question can roaches drown? Cockroach extinction through drowning is difficult and should be undertaken only as a last resort.

If trapping the roach hasn’t worked, eliminating its access to water may do the trick.

The more exposed it is, the easier it will be to kill. Cockroaches may be hardy insects, but it doesn’t make them welcome in your home.

In the event that you discover evidence of an infestation, it is imperative that you act immediately to eradicate the problem.
