5 Surprising Facts About Cockroach Behavior Around Water and How to Deal with Water Bugs in Swimming Pools

Cockroach Behavior around Water:

Adaptability and Resistance

Cockroaches have a reputation for being pests, and with good reason. They can adapt to different environments and are resistant to many forms of pest control, making them a nuisance for homeowners.

One of the factors that contribute to their survival is their behavior around water. In this article, we will discuss the various aspects of cockroach behavior around water, including their adaptability, dependence on water, ability to float, survivability in water, and swimming-up drains and toilets.

Adaptability and Resistance

Cockroaches are known for their adaptability and resistance to various environmental conditions, including water. In fact, they can survive for several weeks without food, but they cannot survive for more than a few days without water.

They have developed various strategies to ensure their survival in water, including their ability to adapt to different water sources, such as sewer systems, drains, and pipes. Moreover, cockroaches are very adaptable in terms of their behavior around water.

For example, they can hold their breath for up to 40 minutes, allowing them to survive in water for long periods. They can also change their crawling behavior to adapt to the flow of water, allowing them to travel through pipes and other water systems.

Dependence on Water

Cockroaches are dependent on water for survival, which makes them attracted to areas with high humidity levels, such as bathrooms, kitchens, and basements. They also prefer to live in moist environments, such as behind refrigerators and under sinks.

This dependence on water is also why homeowners need to eliminate all water sources in their homes, particularly those that are stagnant, to prevent cockroach infestations.

Ability to Float in Water

One of the most remarkable features of cockroach behavior around water is their ability to float. Cockroaches have two spiracles, which are respiratory openings in their bodies located on each side of their abdomen.

When they are in water, they close these respiratory organs, enabling them to stay alive underwater. However, this does not mean that they can swim.

Rather, they float on the water’s surface and wait for rescue or until they can crawl out of the water.

Survivability in Water

Despite their ability to hold their breath and float on the water’s surface, cockroaches can still drown. When they are exhausted or exposed to water for extended periods, they become vulnerable to drowning.

Additionally, if they are submerged in water for several minutes, they may also suffer from hypoxia, a condition where they do not get enough oxygen, resulting in death.

Misconceptions about Drowning Cockroaches

One of the most common misconceptions about drowning cockroaches is how to eliminate infestations. Flushing them down the toilet or drowning them in tap water will not solve the problem.

Cockroaches are good swimmers, and they can still survive even after being submerged in water for several minutes. Moreover, they have a high tolerance for toxins, making many insecticides ineffective against them.

Cockroach Species and Water

It is essential to understand that not all cockroach species are attracted to water in the same way. Some species prefer moist environments, while others prefer dry areas.

For instance, Oriental Cockroaches prefer damp and cool areas, while American Cockroaches and Brown-Banded Cockroaches prefer dry environments. German Cockroaches and Hissing Cockroaches are more adaptable and can thrive in both dry and moist environments.


Cockroaches are a notorious pest that can adapt to different environments and are resistant to various forms of pest control, including water. They are dependent on water for survival, and their behavior around water is remarkable.

They can hold their breath, float on the water’s surface, and survive for extended periods in water. Homeowners can prevent cockroach infestations by eliminating all water sources and understanding that not all cockroach species are attracted to water in the same way.

Finally, it is essential to note that flushing cockroaches down the toilet or drowning them in tap water is not an effective method of eliminating infestations. Cockroaches in Swimming Pools:

Water Bugs vs Cockroaches

Swimming pools are a great place to cool off during hot summer days, but a common problem that pool owners face is the presence of bugs in the pool, including cockroaches.

However, not all bugs in swimming pools are cockroaches, and it is essential to identify what type of bug is present to develop the most effective pest control measures. In this article, we will discuss the differences between water bugs and cockroaches and how to get rid of them in swimming pools.

Water Bugs vs Cockroaches

A common mistake that pool owners make is misidentifying water bugs as cockroaches. However, water bugs and cockroaches are two distinct species that have different behaviors and characteristics.

Water bugs, also known as semiaquatic bugs or true water bugs, are insects that are specially adapted to living in water. They have flat, oval bodies, long legs and antennae, and are typically brown or black in color.

Cockroaches, on the other hand, have a more elongated body with antennas that are shorter than their body length. They are brown or black insects with a hard exoskeleton and are typically nocturnal.

Cockroaches are attracted to a variety of food sources and are often found in kitchens, basements, or other areas with moisture and warmth. One way to identify the presence of cockroaches in swimming pools is to look for their droppings, which look like small brown or black pellets.

Cockroach droppings are usually found along the edges of the pool or around areas where they can access the pool, such as filters or skimmers.

Getting Rid of Water Bugs in Swimming Pools

If you notice water bugs in your swimming pool, it is essential to take action immediately to prevent them from multiplying and taking over your pool. Here are some tips on how to get rid of water bugs in swimming pools.

1. Check Chlorine Levels

Water bugs prefer to live in water that is stagnant or has low levels of chlorine.

If the chlorine levels in your swimming pool are not adequate, it is more likely to attract water bugs. To prevent the growth of water bugs, make sure the chlorine levels in your swimming pool are within the recommended range.

2. Brush and Vacuum Pool

Regularly brushing and vacuuming your swimming pool can help remove any debris or dirt that may be attracting water bugs.

Deep cleaning your pool every two weeks can also help prevent water bugs from growing. 3.

Stay Consistent

Maintaining the cleanliness of your swimming pool is a long-term process, and it requires a consistent effort to keep the bugs away. Make sure you clean your pool regularly, especially after rainfall or storms.

This will help to prevent water bugs from taking up residence in your pool. 4.

Use Detergents

Using detergents can help prevent water bugs from taking up residence in your swimming pool. While detergents won’t kill water bugs, it can make it less attractive to them.

Make sure you choose a detergent specifically designed for swimming pools to prevent damaging the lining. 5.

Prevent Future Infestations

Preventing future infestations is about being proactive and identifying potential entry points for bugs into your swimming pool. Most commonly, water bugs come from stagnant or standing bodies of water, so make sure you eliminate any potential breeding grounds around your pool area.

Refrain from leaving pools of water or containers that collect rainwater near the pool. Additionally, regularly trimming shrubs and bushes to remove stagnant moisture can help prevent water bugs and other pests from finding a home near your pool.



Water bugs and cockroaches are two distinct species that have different behaviors and characteristics. Identifying the right pest that is invading your pool ensures that you develop the most effective pest control measures against it.

For water bugs, keeping chlorine levels optimal, brushing and vacuuming regularly, using detergents, and staying consistent in maintaining cleanliness is vital in preventing infestations. With these measures, your pool can be a refreshing escape from the summer heat without any outside disturbances.

In conclusion, understanding the behavior of cockroaches around water and being able to identify water bugs in swimming pools is crucial for effective pest control. Cockroaches are highly adaptable and resistant pests, which can thrive in moist environments.

Similarly, water bugs, such as semiaquatic bugs and true water bugs, can take up residency in swimming pools if not appropriately managed. By implementing the aforementioned pest control measures, homeowners can enjoy the summer season without worrying about pests taking over their swimming pool area.

With the proper knowledge and tools, we can all better safeguard our homes and ensure that they remain pest-free.
