How to Keep Mosquitoes Away From Your Pool

The mosquito’s bite is unpleasant, and especially pool owners often have a problem with mosquitos. But how do you get control of the mosquito problem near the pool?

You can fight mosquitoes with pesticides or keep them away with electrical devices such as a fan or mosquito trap. Often it is also helpful to use a bug light. However, the best method is proper pool care.

This article provides helpful tips to help keep mosquitos out of the pool.

6 methods against mosquitoes in the pool

I have already listed the most common physical and chemical methods to get rid of mosquito larvae in the pool.

But what should be done when the mosquitoes have already hatched and are bloodthirsty that annoy every swimmer around the pool?

In this case, a long filter run time or a larvicide will not help.

Other measures are required to get rid of the mosquitoes, which I will explain in the following chapters.

#1 Place the fan in the garden to get rid of the mosquitoes

Have you ever heard of a fan keeping mosquitoes out?

It’s true!

Even light breezes are a problem for the mosquitoes with thin wings and low weight.

A large fan – ideally with a battery for better mobility – near your swimming pool would be an easy way to keep flying insects away.

But don’t promise yourself too much from the fan.

The mosquito net and timely removal of mosquito larvae are still better methods of combating mosquitoes.

Still dare to try!

Perhaps this method is the best solution against mosquitoes in your case?

#2 Electric mosquito trap near the pool

The electric mosquito trap is one of the physical methods against mosquitoes in the pool. It is an efficient and, above all, environmentally friendly method against all types of insects.

Simple high-voltage grids are available on the market.

But in principle, all-electric mosquito traps work the same way: The UV light attracts the mosquitoes and gives them an electric shock.

When you buy the electric mosquito trap, it is important to hang it outdoors – devices with a battery are also safe near water.

Tip: The electric mosquito trap works best when other light sources are turned off.

#3 Use insect repellent against mosquitoes in your pool

Insect repellent is not a method of keeping mosquitos out of the pool. But you can avoid unpleasant bites – at least in theory.

Not every mosquito remedy works the same. Most insect repellants won’t stop mosquitoes from taking a bite.

An insect repellent against mosquitoes is still worth trying – the following remedy is also incredibly effective against ticks.

The problem with such agents – which are applied to the skin – is that you, as a bathing guest, add additional colloidal substances to the pool water.

Above a specific limit, this leads to foaming pool water and other cloudiness.

Therefore you should always use a flocculant to filter colloidal substances out of the water. I explain how to do this in my blog post.

#4 Adulticides against mosquitoes in the pool

The larvicide is helpful for mosquito larvae, and an adulticide is used against adult and sexually mature mosquitoes.

To do this, the agent is dissolved in water and applied by spraying – these measures must be carried out by trained pest controllers.

Furthermore, the use of adulticides should only be limited locally in the event of an epidemic or on official orders from health authorities. Source.

#5 Natural predators against mosquitoes in the garden

Eat and be eaten. That sounds cliché, but mosquitoes also have natural predators.

The natural predators of the adult mosquito include:

  • Frogs.
  • Bats.
  • Dragonflies.

Frogs are only an option for natural pools because nobody wants to have frogs in the swimming pool – in the end, you end up with tadpoles in the pool.

However, it looks different if you operate a pond system next to the swimming pool in which the amphibians can live and eat mosquitoes from there.

I want to make it clear: Don’t lure predators like bats into your garden. The bat’s excrements cause other problems, and we don’t want them in the water.

The only thing you should do here is refrain from taking countermeasures against the mosquito’s predators. If bats are flying around your yard, don’t scare them away.

The frog also likes to eat mosquito eggs and mosquito larvae in the pond.

In addition to the frog, other predators ensure that no stinging mosquitoes grow out of the mosquito larvae.

These predators are the best solution against mosquitoes if you have a natural pool. But please pay attention to the animal protection law in your region because sticklebacks are under nature protection in some countries.

#6 Hire pest control companies to kill mosquitoes in the pool

If nothing helps against mosquitoes and swimming in your own pool turns out to be impossible, then it may be time to hire a pest control company.

The experts have experience using adulticides and can find even the most challenging nesting sites.

But be careful: Not every specialist understands their work.

I recommend carefully reading the Google reviews of the individual companies and trusting a company that has experience repelling mosquitoes in the pool.

A list of cooperating companies can be obtained from the local health department.

With these tips, you should be able to bring the mosquito problem in the garden under control yourself – a pest control company should only be the last resort in the rarest of cases.

How to keep mosquitos out of the pool

A practical method of combating mosquito larvae in the pool is to make it more difficult for adult mosquitoes to lay eggs in your pool.

With appropriate measures and simple means, a large part of the mosquitoes can be kept away from the pool – this can bring the problem of mosquito plagues in the garden under control.

You can find my best tips in the following chapters.

#1 Use a pool cover to keep the mosquitoes out

The pool cover is a useful accessory for various purposes.

This not only saves energy in indoor and outdoor pools by reducing the cooling of the pool water – in outdoor pools, this can lead to energy savings of up to 80%.

A pool cover also blocks small animals and insects (in this case, the mosquito) from accessing the pool water.

A pool cover is a must-have, especially when you are away for a long time or on vacation.

A cover for the pool is also used on stormy days.

This minimizes organic contamination and prevents the pool water from becoming cloudy.

Therefore, the pool requires less maintenance.

The pool cover also decreases the need for pool chemicals.

UV rays are reduced and have less of an adverse effect on the oxidation of chlorine and other chemicals.

This means: If the same disinfectants are used, the pool chemistry works longer.

Tip: A solar cover for the pool is convenient. This minimizes the ingress of dirt and heats the pool water. Whereas classic covers are not able to heat the pool water.

#2 Use a mosquito net for the pool

Covering the entire pool with a mosquito net is radical, but it is an effective way to keep mosquitos out of the pool.

This is a complex undertaking for large swimming pools due to the length, but the mosquito net is quickly stretched over the pool for small Intex above-ground pools.

The mosquito net is stretched over the pool with simple ropes – the net must go down to the ground.

The more straightforward method is a pavilion with a mosquito net over the pool.

#3 Pool roof to keep mosquitos away

The roofing for the pool (pool dome) has the same functionality as a simple pool cover, only that it usually retains the heat in the pool much better and does not have to be constantly rolled up.

Especially in the USA (Florida), many pools have a roof – you rarely see this in European countries.

In principle, the roofing is a glasshouse built around the pool. It is available in different price ranges.

I’ve also seen inflatable pool covers that cost significantly less.

But even with a roof, there is the possibility that insects can get to your swimming pool through small notches.

Everyone has to decide for themselves whether the investment is worthwhile.

#4 Swap LED lights to keep the mosquitoes out

Artificial light attracts insects, and scientific studies have shown that electric lamps with a specific light spectrum attract more mosquitoes. Source.

This knowledge resulted in the so-called bug light to reduce the number of insects in the garden.

The traditional incandescent, CFL, halogen, and LED lamps with a cool temperature have attracted most insects.

So it can be helpful to replace the lights near the pool to keep mosquitoes and other insects away from the pool water.

#5 Promote garden maintenance

What does garden maintenance have to do with the mosquito epidemic at the pool?

Quite simply: Mosquitoes use every opportunity there is to lay eggs. Be it a small puddle in the garden, standing water buckets, dead trees with holes, rotting leaves, or tall grass.

Regular garden maintenance can bring the mosquito problem around the pool under control.

  • Remove tall grass with the lawnmower.
  • Dump standing water out of the containers.
  • Use a suitable cover (lid and nets) on rain barrels to make the containers safe.
  • Puddles in the garden can be treated with larvicide, and the ground can be leveled to avoid large puddles.
  • Dead logs and holes in trees should be sealed.
  • Throw rotting leaves in the composter and cover it.

#6 Plants against mosquitoes near the swimming pool

And when we get to gardening, how about a few plants to keep the mosquitos away from the pool?

After all, sweat and other strong smells attract mosquitoes. So it would be logical to assume that other fragrances also keep them away?

In principle, all plants with a high proportion of essential oils are said to drive away mosquitoes.

That would be the following:

  • Frankincense – also known as the harp bush – is very effective.
  • Scented pelargoniums: Look beautiful and smell wonderful.
  • Lavender: A classic against mosquitoes.
  • Catnip: Stronger than chemical insect repellants.
  • Marigolds: Unpleasant for all flying insects.
  • Walnut tree: A well-known mosquito repellent.
  • Lemon balm or lemongrass.
  • Spices: Basil, rosemary.
  • Vegetables: Tomato, garlic.

It takes a little effort to grow all kinds of plants in your garden against mosquitoes.

Nevertheless, the fragrant plants cannot guarantee that bathing will be mosquito-free in the future.

But you have a lovely garden and a natural privacy screen in the end.

Alternatively, you can try scent traps against insects.

FAQ about mosquitoes in the pool

Many readers have a problem with mosquitoes near the pool.

Therefore I want to answer some open questions regarding mosquitoes.

Do ultrasound devices work against mosquitoes?

In some guides, it is advised to use ultrasound devices against mosquitoes.

The ultrasound is supposed to keep the mosquitoes away from the pool and protect us.

That sounds good, but unfortunately, ultrasound devices don’t work against mosquitoes.

This is because the mosquito’s hearing limit is 2000 Hertz. The ultrasound is significantly higher at 20 kHz – 10 GHz.

And if you are wondering whether the anti-mosquito app works.

No, it doesn’t work!

Do home remedies help against mosquito larvae?

Home remedies can help against mosquito larvae in the pool, but they create other water balance issues.

Mosquito larvae are eliminated by suffocating them. Vegetable oils form a thin film on the water’s surface and prevent the larvae from breathing.

But the vegetable oil leads to clouding of the pool water and is therefore not a suitable option for serious pool owners.

You should also stay away from other home remedies.

Every entry of organic substances disturbs the water balance in your swimming pool.

Can chemicals help keep mosquitos out of the pool?

Yes, chemical agents help keep mosquitos out of the pool, including adulticide.

During my research, I discovered that larvicide is a proven chemical agent – also in the private sector – to keep mosquitoes away from the pool.

The larvicide is explicitly aimed against mosquito larvae and the later developed pupa.

But how high does the amount have to be, and how often does the chemistry have to be used?

I couldn’t find a study that gave concrete results using an experiment. Furthermore, in some areas, the health department regulates the use of adulticide.
