Water Bugs in Swimming Pools: How to Identify, Remove & Prevent Them

Why Water Bugs Invade Swimming Pools
If you’ve ever noticed tiny bugs gliding across your pool surface or swimming just below the waterline, you’ve likely encountered water boatmen or backswimmers. While these insects are common in ponds and lakes, they can invade backyard pools that have the right (or wrong) conditions — especially when algae or stagnant water is present.
Both insects are attracted to water that offers food, shelter, and warmth, but knowing which species you’re dealing with can help you eliminate them safely and prevent them from coming back.
🪶 Water Boatmen (Corixidae)
What They Look Like:
Water boatmen are small, oval-shaped insects (about ¼ inch long) with flattened bodies and oar-like hind legs. They are non-biting, and their silvery underside allows them to glide smoothly through the water.
Preferred Habitat:
They thrive in ponds, lakes, and slow-moving water rich in algae and organic matter. When your pool water becomes slightly green or unbalanced, it mimics their natural habitat.
How They Get Into Your Pool:
Water boatmen are attracted to light reflections on pool water at night. They often fly toward illuminated water surfaces and will stay if they find algae or microorganisms to feed on.
How to Remove and Prevent Them:
-
Brush and vacuum the pool walls and floor to eliminate algae.
-
Shock the pool to kill microorganisms.
-
Balance pH and sanitizer levels to discourage regrowth.
-
Turn off pool lights when not in use at night.
-
Install a copper ionization system to prevent algae naturally.
🪰 Backswimmers (Notonectidae)
What They Look Like:
Backswimmers are slender, elongated insects that swim upside down (white belly up). They prey on other insects — especially water boatmen.
Do Backswimmers Bite?
Yes. Unlike water boatmen, backswimmers can bite humans. Their bite feels similar to a bee sting and may cause temporary pain, redness, or swelling.
First Aid for Backswimmer Bites:
-
Wash the affected area with soap and cool water.
-
Apply a cold compress for 10–15 minutes.
-
Use an anti-itch cream or oral antihistamine to relieve discomfort.
-
Seek medical care if swelling or allergic symptoms occur.
How They Get Into Your Pool:
Backswimmers are drawn to pools that already have water boatmen — their primary food source. If you have one, you’ll likely see the other.
How to Remove and Prevent Them:
-
Eliminate algae and water boatmen first — remove their food source.
-
Shock and circulate the water to sanitize.
-
Skim and vacuum to remove any visible insects.
-
Maintain good water balance and circulation to keep them from returning.
⚗️ Why Copper Ionization from Intec America Is the Best Solution
Traditional chlorine and saltwater systems may temporarily kill algae, but once sanitizer levels drop, algae — and water bugs — come right back.
Copper ionization from Intec America is a superior, long-lasting alternative:
-
🧪 Copper ions eliminate algae at the root, removing the food source that attracts water boatmen.
-
🌿 Silver ions destroy bacteria and microorganisms naturally.
-
💧 No harsh chemicals — ionized pools stay crystal clear without chlorine odors or skin irritation.
-
💰 Lower maintenance costs — fewer chemicals, less corrosion, and longer equipment life.
-
⚡ Continuous protection — copper and silver ions stay active even when your pump is off.
No algae means no water bugs.
