While not essential, as long as you take helpful preventative steps, algaecides can give you the added power to kill all algae effectively. This can be especially helpful if you have already tried other pool cleaning methods.

Make sure you choose a good but strong enough algaecide, but you should also be aware of the chemicals present and how they can change the safe composition of the pool.


Vacuuming your pool can result in the killing of all bugs and the removal of all algae, debris, and other possible debris in your pool. This can also ensure that the entire bottom of the pool is clean enough to be safe enough again.

Algae will be more likely to grow with this change in pH. Be sure to restore the pH of the pool so that it is safe to swim again.

Pumping is something you should do regularly to keep your pool clean and safe. In fact, pools designed for this purpose usually come with built-in pumps.

correct stagnation

Stagnation is a common reason why your pool water allows algae to grow and attracts insects. Because the water in your pool stops flowing well and sits still for a long time, it can become significantly dirty.

It can allow mosquitoes and other insects to use the water to breed and lay eggs, leading to the spread of these insects around the pool and inside your home.

It also puts you at risk for various diseases. You can deal with this stagnation by fixing possible leaks and making sure all holes are filled with water.

light vegetation

In addition to the algae that is present in your pool, you may also have vegetation such as plants around your pool. While they add aesthetic value to your pool, they can also attract a variety of insects, since many insects feed on this type of vegetation.

Make sure there is enough distance between your pool and these plants, shrubs or trees. You should also trim this growth back regularly so it doesn't get too close to the pool.

If you notice insects near the plants, you can use a spray or pesticide to control them.

This is a simple but effective and necessary measure that you should definitely do. Regular cleaning of your pool can help keep the water safe enough that you don't get rashes or irritants on your body.

Accidentally ingesting dirty pool water can also lead to the spread of various bacteria and diseases. By regularly cleaning your pool with rakes, vacuums and pumps, and by covering the pool when not in use, you can ensure that your pools remain safe from pests.

You should also drain and replace the pool water from time to time.


A good way to get rid of organic matter in your pool can be to use oxidizers, which you can easily buy at your local store. These oxidizers are also safer to use compared to increasing chlorine levels in the water.

However, keep in mind that oxidation is most useful for removing various types of dirt and preventing the pool from attracting insects. Getting rid of algae may not work as well if it's already forming in your pool.

positioning of lights

Lights are a sure way to attract insects. If you place lights around your pool, they will end up accumulating different types of insects, which is exacerbated by the presence of the pool.

Before installing lights around the pool, be sure to place them a bit further away from the pool.


In addition to the steps above, it's important to monitor your pool regularly so you can catch bugs early and prevent them from spreading further. You should do this especially if the pool is not going to be used in a certain season.
