How to Keep Frogs Out of Your Pool (7 Proven Methods)

Frogs have no place in a pool. But what should you do if you spot a frog in the pool, and how can you drive the amphibians away?

The frog is useful against many harmful insects and should not be killed. But as a pool owner, protective measures in the form of pool covers or a pool fence can be installed to scare away frogs.

I’ll show you the best ways to keep frogs out of the pool. I will also explain important basics to you about the Nature Conservation Act.

Removing frogs from your pool is not easy. The much better solution is to prevent the frogs from jumping into the pool in the first place.

How to keep frogs out of the pool

But be careful: Some frogs are under nature protection, and therefore how frogs are driven away from the pool is crucial.

In the following chapters, I will show you exactly how to get rid of frogs in your pool and which methods have proven themselves in practice.

1. Use a pool cover against frogs

The easiest way to prevent frogs from getting into your pool is with a pool tarpaulin.

The cover not only prevents the frog eggs from being laid but also serves as thermal isolation for your pool.

Solar tarpaulins, which additionally heat your pool, are practical – savings of up to 80% in heating costs are realistic.

The cover is pulled over the pool after the bath is finished or if you are absent for a long period.

With the pool tarpaulin, you have further advantages as a pool owner:

  • Insects are prevented from falling into the pool water.
  • Leaves, sand, and other contamination are minimized.
  • A longer-lasting effect of pool chemicals thanks to protection against UV rays.

It is important that the pool cover is large enough and covers the entire water surface. The tarpaulin can also be used later when the pool is wintered.

2. Build a fence around the swimming pool

One way to keep frogs away from your pool is a fence around the garden.

The best way to do this is to use a wooden fence at least 50 cm high and does not allow the frog to climb through the space.

The fence around your own garden doesn’t just keep frogs away from the pool. A fence is helpful against other wild animals such as hedgehogs, squirrels, rabbits, or the salamander.

If you cannot fence in your entire garden, then there is still the option to only secure the area around your pool with a fence.

A fence around the pool is also a good child safety measure and worth the investment.

Tip: A wire fence is unsuitable for keeping wild animals such as the frog away from your pool. The fence must also be secured against frogs with a fine-mesh garden net or wooden slats – with a minimum height of 50 cm.

3. Turn off the lights around the pool

The artificial light attracts certain amphibians, but the frog does not.

Nevertheless, LED lamps or light bulbs in your garden indirectly influence frogs.

Artificial light (especially cold light) attracts insects, and where there is plenty of food, frogs and other predators are not far away.

Unfortunately, the frogs are blinded by artificial light sources, and it often happens that the frog accidentally falls into the pool water.

When you leave your pool, it is best to turn off the lights in the garden to avoid attracting insects.

An alternative would be the Bug Light.

This yellow lamp has been scientifically proven to attract fewer insects in the garden.

4. Keep the pool water moving

Still water also automatically attracts more insects such as mosquitoes.

Many mosquitoes and other insects mean a rich food supply for frogs, and amphibians cannot miss that.

Therefore, you should ensure that the pool water is sufficiently circulated in your pool to keep insects away.

In the best scenario, the frogs lose interest in getting near your pool.

The pool pump should run for at least 6 to 8 hours every day. During this time, the pool water should be entirely circulated by the pump at least once.

In addition, you can mount a fountain or a small waterfall to ensure water circulation outside of the running times of the pump.

The advantage of fountains is that they consume significantly less electricity than pool pumps and are also suitable for your pool’s massage function.

5. Keep insects away from the pool

Frogs are indirectly driven out of the swimming pool when there is no food available in your pool, and these are insects.

No insects in the pool = No frog in the pool.

I have already listed two specific measures of how to keep insects away from your pool.

But that’s not all!

In my article, I describe other methods of eliminating insects in pool water. Just follow the link.

6. Heat the pool water against frogs

Frogs avoid water that is too warm and prefer cold water.

The reason is: There is more oxygen in cold water, and since frogs supply the blood with oxygen through their skin, the amphibians feel more comfortable in cold water.

You can heat your pool in different ways:

  • Solar cover: This covers the pool, prevents heat loss, and heats the pool’s water.
  • Solar rings: The rings float on the water’s surface and, if there is enough sunshine, also heat the pool water.
  • Pool solar heating: Solar heating consists of black hoses. These are switched into the water cycle and transfer the stored heat to the water flowing through.
  • Pool heat pump: The heat pump for the pool is a little more expensive but independent of the sun and much more effective when heating the pool – do not buy a heat pump below 8 kWh!

The warm water will not completely drive the frogs away from your pool, but they will try to get out of the pool themselves after the first bath in the warm pool water and look for other water sources.

That is why a suitable aid for animals to get out should be in every large swimming pool.

7. Mount the frog exit aid

Frogs need an exit island to get out of the pool.

A pool ladder or a floater is not enough. The frog can hold onto this, but it is difficult to get out of your pool.

You can find various exit aids for frogs and other animals such as squirrels and hedgehogs.

If the pool water is too warm, the frog will try to get out of your pool and struggle hard – in the worst case, the frog drowns if its strength fails.

If you don’t want to keep netting any drowned animals out of your pool, I advise you to use the pool exit island.

With this little tool, you support nature and species protection.

Tip: In small pools, one exit aid is usually enough. In large pools, I recommend using 2 exit aids.

8. Keep going with your garden maintenance

Grass and thick foliage are almost as good for frogs as a swim in your pool. There are excellent hiding spots for the frog here.

The next time you are tending your yard, remove the tall grass near the pool and move on with general garden maintenance.

But please refrain from using weed killers that contain glyphosate when caring for the garden – handle the toxic agents carefully.

The glyphosate is fatal for the frogs if it comes into direct contact with the skin and inhibits embryonic development.

The next time you use chemicals, keep in mind that the frogs are killing off many disease-transmitting insects that can harm your health.

Are frogs dangerous to humans in the pool?

So you’ve spotted frogs or tadpoles in your pool, and you’re wondering if these amphibians are harmful to you and your kids?

The fact is: Most frogs in the US are harmless to humans and animals.

Only the yellow-bellied toad (also called mountain toad) can cause eye irritation on direct contact – major damage has not been documented. You can recognize the little frog by the bright yellow warning color.

Therefore, a frog in your pool is not a great danger and is useful for combating insects such as mosquitoes in the pool.

The only way frogs could disturb the balance in the pool water is that the bacteria adhering to the body get into the pool.

But with the proper use of disinfectant in the pool, this shouldn’t be a problem.

I want to mention two other reasons you should take measures to keep frogs away from pool water.

Frogs lay eggs in pool water

Frogs belong to the group of amphibians and reproduce by laying eggs – these are also known as frogspawn.

In case you’ve never seen a frog spawn before, it resembles tiny jelly-like air bubbles that are deposited as a mass. The eggs are transparent on the outside, and there is a black dot in the middle.

For the frogspawn to become small frogs, the eggs must lie in the water. Otherwise, the embryos will dry up and die.

Over time, the eggs turn into small tadpoles in your pool, which can later only be fished out of the pool water with a lot of effort.

It is therefore important to keep frogs away from your swimming pool.

If there is already a frog spawn in your pool, it is important to relocate them in a species-appropriate manner.

I will explain how to do this in my blog post about tadpoles.

Frogs are drowning in the pool

Another reason why you don’t want frogs in your pool is that they drown or starve and contaminate the pool water.

Once a frog has fallen into a pool – regardless of whether it happened voluntarily or unintentionally – it is difficult for the frog to get out of its own strength.

The distance between the pool’s edge and the waterline is too great to climb out. Even the pool ladder is not suitable for frogs to get out.

And let’s be honest: Nobody wants to see a dead frog floating on the surface of the pool. In the worst case, maggots develop in your swimming pool from the dead frog.

Therefore, installing suitable defense mechanisms against frogs in the pool is necessary.

Questions and answers about frogs in the pool

Below I answer the most common questions about frogs in the pool.

In this way, I am making a small contribution to the confusion about frogs and hopefully clearing up any remaining obscurities.

Can you drive away frogs with an ultrasound?

The hearing range of frogs is around 50-4,000 Hz and is relatively small compared to other living things.

The frogs would not perceive the ultrasound, and therefore ultrasound devices do not help drive away frogs.

Can frogs drown in the pool?

Frogs are excellent swimmers and do not drown as easily.

These will cling to possible pool ladders or pool floaters. Even self-floating leaves are enough for the frog to float with little effort.

If the frog lies in the pool for a long time, it may struggle to death and drown in it.

For this reason, I recommend installing suitable exit aids for animals.

Does coffee help scare away frogs?

Indeed, coffee can injure and even kill frogs.

The frogs oxygenate the blood through their skin. If these are sprayed with coffee, the frog dies.

Under no circumstances should you splash coffee on the frogs!

I cannot say whether it is legally permissible to sprinkle coffee around the pool to keep the frogs away from your pool.

However, it is assumed that the smell of coffee is perceived as unpleasant for the frogs.

Use the chlorine against frogs?

The chlorine is part of the standard treatment of the pool and is irritating if it comes into direct contact with the skin.

If frogs come into direct contact with chlorine, they will likely die.

But how well do the frogs tolerate the chlorine in the pool water?

In a diluted form, the chlorine in the pool is not harmful to the frogs. However, amphibians should not stay in the pool for long periods as they absorb oxygen through their skin.
