If you’ve ever spotted fast-moving bugs zipping around in your pool, you’ve probably found yourself thinking, “What on earth are these water bugs in my pool?” Trust me, I get it—it’s unsettling! While most of these little critters are harmless, they can definitely make your pool feel less inviting. So, let’s take a dive into the world of water bugs! I’ll help you figure out what they are, why they’re showing up, and, of course, how to kick them out of your pool for good.
What Are Water Bugs in Your Pool?
Water bugs are typically aquatic insects that love to swim in pools and ponds. They are often attracted to standing water, such as your pool, where they find an abundance of food and space to lay their eggs. When you spot swimming bugs in your pool, you may be dealing with different types, including water boatmen, backswimmers, or even some types of beetles.
These bugs can vary in size, and some even bite. The most common types of bugs in pool water are:
- Water Boatmen: These bugs swim on the surface of the water and are harmless.
- Backswimmers: These bugs tend to swim upside down and can bite if provoked.
- Water Scorpions: With their long, spiny legs, they can look intimidating but aren’t dangerous.
Now that we know what these insects are, let’s talk about why they show up in your pool in the first place.
Why Are There So Many Water Bugs in My Pool?

There are several reasons you might see an increase in bugs in pool water:
i. Standing Water
Water bugs love standing water, and if your pool isn’t used frequently or if it’s left uncovered for too long, bugs will find it an ideal breeding ground. Algae growth in your pool also serves as a food source for many types of water bugs.
ii. Food Source
Water bugs in your pool feed on algae, small organisms, and debris that accumulate in the water. If your pool has not been properly cleaned or shocked recently, it might provide a perfect environment for these bugs to thrive.
iii. Lack of Pool Maintenance
When pool water is not maintained correctly, bugs can become more prevalent. Without regular cleaning, algae can build up, which creates a favorable environment for bugs like water boatmen and other pool bugs.
iv. Uncovered Pools
An uncovered pool during the night or when the temperature is warm will attract insects. Bugs are especially active at night and are drawn to water sources for both drinking and laying eggs.
v. Pests Laying Eggs
Certain bugs, like water boatmen, lay their eggs in the water. These eggs can hatch into larvae, which later become adult bugs. If your pool has standing water and debris, it’s more likely to attract insects to lay their eggs.
Types of Swimming Bugs in Pools

As mentioned earlier, there are several types of bugs that you may find swimming in your pool. Each one behaves a little differently, so it’s important to understand their characteristics to handle them effectively. Here’s a closer look at the main types of swimming bugs in pools:
Water Boatmen
Water boatmen are small, aquatic insects that glide across the surface of the water. They are harmless and don’t bite, but their presence can be a sign that your pool needs cleaning. They are known to swim on their backs and feed on algae, decaying organic matter, and small aquatic creatures.
Backswimmers
Unlike water boatmen, backswimmers swim upside down. They have long, spiny legs and can bite if disturbed, making them less friendly pool companions. Backswimmers are predatory and feed on smaller bugs, tadpoles, and other tiny organisms in your pool.
Water Scorpions
These long, spiny insects resemble scorpions but are not dangerous to humans. They feed on smaller aquatic insects and are typically found in pools with excessive algae or organic material. While they don’t bite humans, their appearance can be quite unnerving.
Other Pool Bugs
Apart from the usual suspects, you may also find tiny pool bugs like mosquitoes, midges, and even beetles. These bugs typically arrive in large numbers and can be a sign of poor pool maintenance or a nearby source of standing water.
How to Get Rid of Water Bugs in Your Pool
Dealing with water bugs in your pool doesn’t have to be a stressful task. Here are some practical steps you can take to remove them:
a. Regular Pool Maintenance
The best way to prevent bugs from invading your pool is through regular maintenance. This includes:
- Skimming debris: Remove leaves, twigs, and other organic material from the pool regularly.
- Vacuuming the pool: A pool vacuum will help remove dirt and debris from the bottom of your pool.
- Shocking the pool: Shocking your pool will kill bacteria, algae, and other pests in the water, helping to keep the water clean and clear.
b. Removing Algae
Algae can provide a food source for water bugs. To keep your pool free from algae growth:
- Use algaecide products to prevent algae buildup.
- Keep your pool’s chlorine levels balanced to discourage algae growth.
c. Covering Your Pool
Covering your pool when not in use can help keep bugs in pool water at bay. A pool cover prevents insects from landing in the water and laying eggs.
d. Using Insecticides
If bugs are particularly problematic, you can use insecticides designed for pool use. However, be cautious about the chemicals you use. Ensure that the product is safe for both your pool water and the environment.
e. Consider a Pool Filter Upgrade
A pool filter that is too weak might allow algae and debris to build up, creating an inviting habitat for water bugs. Consider upgrading to a stronger filter to ensure your pool stays clean and bug-free.
f. Adding Dish Soap
In some cases, adding a small amount of dish soap to your pool can help suffocate water bugs, making it easier to remove them from the water. However, use this method sparingly to avoid damage to your pool’s surface.
