Swimming Pool Bugs That Bite

Swimming Pool Bugs Types 

Different types of pool bugs can infest your swimming facility, but the most common ones are Back Swimmers, Boatman, and Thrips.

They look alike, although one can bite you while the other is harmless.

Water Boatmen

Water Boatmen or corixidae look scary to the eye, but they are not harmful to the swimmer.  

They are oval-shaped bugs and usually greenish-brown or brown, with large eyes.

Water Boatmen appear in the pool to feast on plant matter, algae, mosquito larvae, and microorganisms.  

Backswimmers Bugs

You can confuse them for Water Boatmen, although their back legs are more massive.

The primary difference is they swim on their back or upside down, and they bite.  

Their bit is not poisonous but can be quite painful – like a bee sting.

They settle in your swimming pool because they eat bugs, including the Boatmen. 

That means you can eliminate them by getting rid of their food supply, which is Water Boatmen. 

How to Get Rid of Water Boatmen

You can do the following things when getting rid of Water Boatmen:

  1. Remove the Bugs: Use a skimmer or leaf rake to catch these creatures and relocate them to another place. 
  2. Vacuum the Pool Manually: Vacuuming will remove organic foods, like algae.
  3. Brush the Pool: Remember to brush the ladders, steps, and walls to loosen the algae.
  4. Test the Water: Always ensure that the water pH is 7.4-7.6, and the alkalinity is 120-150 ppm to prevent algae development.
  5. Shock the Pool: Use about 20 liters of chlorine to shock a pool of 45,000 liters. You can increase the dose if the pool is full of algae.
  6. Run the Pump: Running the pump for about 24 hours can circulate the chemicals and eliminate dead algae.


Thrips are small plant-feeding bugs that live in hayfields, grass areas, and pastures.

They can be blown to your swimming pool by the wind, or they can fly.  

After landing on a swimmer, object, or plant, they scrape the skin or surface with their mouthparts while attempting to drink water or feed, causing the bite feeling. 

If you are wondering “how to keep thrips from biting me” then the solution is to apply 100% DEET on your necks, legs, and arms. 

You can also apply other products that can help to repeal these bugs.

In Conclusion

You can remove and prevent pool bugs from coming to your pool by ensuring that the facility is balanced.
