There are two common types of water bugs that are a nuisance to pool owners and managers:

Water Boatmen

Looking forward to summer travel and water fun this summer? There are few summertime pleasures that beat time spent in the water. If the sight of bugs sharing your pool isn’t bad enough, some of the culprits actually bite. Water bugs are one of these pests! You will find a lot of them in pools, ponds, lakes and freshwater streams. Water bugs can grow up to more than 12 centimeters long, although the average length is just two centimeters. These are oval-shaped bugs that eat algae, mosquito larvae, and other water microorganisms. Fortunately, they do not bite. They need to breath air so they can be drowned, but they can also fly and lay eggs in pool algae.

They also breath air and are thinner than boatmen, so they surface a lot and skim across the water. They eat other bugs like the boatmen and beetles. Unfortunately, they bite and can also fly. They lay eggs in pool algae similar to the water boatmen.
How to Get Rid of ThemTaking away their food supply is the best way to get rid of these pests, so start with removing your pool of algae. To do that, there’s a simple process called Shock Chlorination. Chlorination kills organic material in the pool, and therefore eliminate the pool algae that grow. Here’s a guide on how to shock chlorinate:
1. Do this on dusk or nighttime to prevent the sun from burning the chlorine too quickly
2. Wear safety goggles and rubber gloves
3. Fill a 5-gallon bucket with water but leave enough room so it doesn’t spill
4. Add 1 pound of chlorine shock (calcium hypochlorite) to the bucket. For every 10,000 gallons of water your pool has, add 1 pound of shock.
5. Stir the mixture gently
6. Make sure your pool is running and leave it overnight / or for 8 hoursAfter successful shock chlorination, use your pool brush to scrub the walls and floor of your pool. This loosens up any algae that has been growing.

Once the algae are gone, the water bugs won’t have any food and will move out. If some don’t, you can eliminate them for good. How?

1. Get a bucket (with a lid) of pool water
2. Pour oil in it, such as cooking oil
3. Skim out the bugs from your pool using a pool skimmer, and put them in the oil bucket
4. Close it up and wait for a few days
5. Dispose the contents in a sealed container with the trash
5. Do not drain your oil as your sewer pipes may become clogged.
That’s it for eliminating water bugs in your pools. Tune it next time for more pest control tips! If you have any more pest problems you’re not sure you can handle, don’t hesitate to contact professionals.
