With this, we would like to make your purchase decision easier and help you find the best mosquito plug for you.

You will also find answers to frequently asked questions in our guide. If available, we also offer interesting test videos. Furthermore, you will also find some important information on this page that you should definitely pay attention to if you want to buy a mosquito repellent.


  • A mosquito bug effectively protects you from mosquitoes and helps you get a good night’s sleep without mosquito bites.
  • Mosquito bugs can repel or kill mosquitoes in different ways. A distinction can be made between mosquito bugs that vaporise a biocide, ultrasonic mosquito bugs and bugs that work with UV light.
  • Since mosquito plugs are designed for certain animals and the effect is suitable for different room sizes, you should pay attention to the manufacturer’s instructions when buying a mosquito plug.

The Best Plug: Our Picks

Guide: Questions you should ask yourself before buying a mosquito plug

How does a mosquito bug work?

The mosquito repellent works in different ways depending on the type of model.

Basically, mosquitoes are either repelled or killed by the mosquito repellent and thus rendered harmless.

The mosquito repellent is very easy to use. All you need is a power socket to which you connect the mosquito plug. It then works independently and can be operated with the help of an on/off switch if necessary.

A distinction can be made between mosquito plugs that release an insecticide into the air, those that work with ultrasonic waves, and mosquito plugs with UV light that kill insects with an electric shock. We will go into more detail about the different modes of operation later in our decision section.

Where can I use the mosquito repellent?

The mosquito plug is usually only suitable for indoor use.

There is no point in using a mosquito plug outdoors, as it is not effective there or loses a large part of its effect.

Whether in the bedroom, kitchen, living room or bathroom – the mosquito plug can be placed anywhere in the room where there is a socket.

Mosquito plugs that work with insect venom are not suitable for children’s rooms.

Against which animals does a mosquito repellent work?

Basically, the mosquito plug combats those insects and animals that are explicitly named by the manufacturer.

These often include common mosquitoes as well as houseflies and fruit flies. Tiger mosquitoes can also be controlled with many plugs.

Mosquito plugs that function via ultrasonic waves can even repel fleas, mice, rats, cockroaches and martens by selecting different frequencies.

Mosquito bugs that work with UV light and electric shock usually also control moths and gnats.

What alternatives are there to mosquito bugs?

Apart from mosquito bugs, there are many other ways to protect yourself from mosquitoes. These include mosquito and pest sprays, fly screens and mosquito nets, as well as essential oils and natural plants.

Flycatchers and mosquito magnets can also be helpful alternatives.

Here we have summarised the mentioned alternatives at a glance:

Alternative Description
Mosquito spray Mosquito sprays are applied directly to the body and protect against mosquito bites due to their smell. The effect of the product lasts for a few hours and dissipates over time, which is why the protection must be renewed after a given time – at the latest the next day. Mosquito sprays are good for protection when you are outdoors.
Fly screens Can be attached to windows and doors. The tried and tested screen provides a physical barrier that prevents mosquitoes from entering the room and allows you to ventilate without worry.
Fan A fan that is switched on can not only have a cooling effect in summer but also keep mosquitoes away, as they do not like draughts.
Mosquito net Placed over the bed, the net acts as an impenetrable barrier against mosquitoes and effectively protects against mosquito bites at night.
Essential oils Natural method in which the smell keeps mosquitoes away. Suitable ones include lavender, eucalyptus, basil, sage, rosemary, cedarwood and citronella. However, some people are allergic to the oil vapours that are released into the air they breathe. Available in the form of scented candles and lamps, as incense sticks or as pure oil. Well suited for outdoor use.
Plants Plants can also be used to repel mosquitoes. They also contain essential oils and can be placed at the window or on the terrace, for example. Lavender, tomato, lemon balm, basil, rosemary, garlic, lemongrass, marigold and lemon geranium are particularly good for repelling mosquitoes. Walnut twigs also help.
Fly catcher The insect catcher is simply attached to the ceiling and dangles in the air. Mosquitoes and flies stick to the tape with the sticky surface and die there.
Mosquito Magnet The magnetic trap keeps areas up to one acre free of mosquitoes by using a catalyst to convert propane into CO2, heat and moisture to mimic human breath. The device is suitable for use in all weather conditions, works on batteries and protects against mosquitoes for months. Very effective but also very expensive.

Decision: What types of mosquito repellent are there and which is the right one for you?

If you want to buy a mosquito bug, you have the choice between three different models, which differ in the way they work. Accordingly, we can differentiate between the following types of mosquito bugs:

  • Biocide vaporiser
  • Ultrasonic mosquito biter
  • Mosquito biter with UV light

We have compared the different mosquito bugs with regard to their characteristics in order to make your decision as easy as possible.

What distinguishes a biocide vaporiser and what are its advantages and disadvantages?

The biocide vaporiser works with an insecticide that is heated by an electric current and thus evaporates. In this way, the biocide is distributed in the air and mosquitoes are rendered harmless. The nerve poison stuns the mosquitoes or puts them completely out of action.

There are two types of electric vaporisers, which work with a vial of liquid active ingredient or with platelets (with integrated heating plates). Both media can be exchanged when the active ingredient is used up.

  • Very effective, usually more effective than alternative models
  • Odourless
  • Produces no noise
  • Easy to use, as often with practical on/off switch and control lamp
  • May be harmful to health as chemical agent is released into the air
  • Not suitable for babies, children, pregnant women and allergy sufferers, only conditionally suitable for animals
  • Active agent must be refilled regularly
  • Effect of the plug is sufficient for max. 20 m² environment

The variant with vial often has a practical on/off switch that you can use to control the release of the insecticide. Biocide vaporisers with small plates release the active ingredient continuously.

The biocide is odourless and very effective. However, the properties of the biocide vaporiser are associated with various advantages and disadvantages that you should be aware of.

What are the characteristics of an ultrasonic mosquito repellent and what are its advantages and disadvantages?

The mosquito plug with ultrasonic technology keeps insects away by continuously emitting a high-frequency sound, which the animals perceive as very unpleasant and which can damage their olfactory and nervous central system.

This non-toxic method does not kill mosquitoes, but only drives them away.

You should be patient when using the ultrasonic mosquito repellent because it takes 2-3 weeks for it to take full effect.

Depending on the frequency setting, you can also deter other animals:

Frequency Animals controlled
7 000 Hz Mosquitoes and fleas
10 000 Hz Flies, rats and mice
12 000 Hz Martens and cockroaches

A high-frequency mosquito repellent has various advantages and disadvantages, which we have listed and compared.

  • Works without chemical agents
  • Can be used without hesitation and is also suitable for children’s rooms
  • Different adjustable high frequencies repel different animal species
  • Also suitable for larger rooms (over 100 m²)
  • Animal-friendly
  • Not as effective as alternative models
  • Female mosquitoes, which often have poorer hearing, are not always deterred by the high-frequency sound
  • Usually only takes effect at an advanced stage
  • Can also produce perceptible noises depending on the frequency

What distinguishes a mosquito plug with UV light and what are its advantages and disadvantages?

The mosquito plug with UV light attracts insects by means of the light and then kills them directly with an electric shock at an integrated high-voltage grid.

The ultraviolet light also attracts other insects such as moths and mosquitoes, but body heat is even more attractive to mosquitoes, which is why the mosquito plug often only provides limited protection against mosquito bites.

  • Can also function as a night light
  • Rapid death of insects by means of electric shock
  • Works without the use of chemicals, therefore completely harmless to use
  • Only partially effective, as mosquitoes are attracted to heat rather than light
  • Dead animals must be removed regularly
  • Basically very animal-unfriendly method
  • Can cause noise

The mosquito plug with UV light also has various advantages and disadvantages, which we have summarised for you below.

Buying criteria: You can use these factors to compare and evaluate mosquito bugs

Here we help you compare mosquito repellents and find the right one for you.

The following criteria have proven to be useful in assessing which mosquito repellent is best for you:

  • How it works
  • Area of application
  • Duration of action
  • Effectiveness

In the following, we show you what is important in the different criteria and what you can look out for.

How it works

There are three different types of mosquito nets, which differ in the way they work. We have already presented the corresponding types in our decision section.

The most proven mosquito repellent is the biocide vaporiser, which reliably protects against mosquitoes and usually kills or stuns them with the insecticide. However, you have to make concessions in the area of application (our next criterion).

Models with UV light and ultrasound technology are not always 100% effective, but their chemical-free mode of action is completely harmless. The former kill the insects effectively, the latter only repel the mosquitoes.

Depending on whether you only want to keep the mosquitoes away or completely put them out of action, one mosquito repellent is more suitable than another.

The range of application is also linked to the function of the mosquito repellent, which we will discuss in the next section.

Area of application

With regard to the area of application, the question arises as to where you want to use the mosquito bug.

The manufacturers of the mosquito repellent provide information on how many m² the effect of the plug is sufficient for and whether the mosquito plug is suitable for indoor or outdoor use. You should take this information into account when purchasing a mosquito repellent.

If it is a child’s room in which you want to install the mosquito plug, you should keep your hands off biocide vaporisers.

However, unlike ultrasonic mosquito bugs, these are generally suitable for smaller rooms. Mosquito bugs that work with high frequency can also be used in larger rooms and even work when windows and doors are open.

Mosquito bugs with UV light are also effective outdoors. However, as these plugs attract insects through the light, they can also attract animals from the surrounding area, which is why it is advisable to use the plug only in closed rooms despite the given effect.

Duration of effect

If you want to protect yourself against mosquitoes throughout the summer, the duration of the effect is also an important aspect to consider.

Biocide vaporisers often have an effective time of 8 hours a day and can be used for about a month on average before you need to renew the active ingredient.

Depending on the model and price, the duration can vary between 10 and 60 days, which is why it makes sense to take a look at the duration of action before buying. The shorter the duration of action, the more often you have to buy and replace the active ingredient medium, which is associated with additional costs.

Mosquito repellents that work with ultrasound or UV light can usually be used for several seasons and only need to be replaced when they become defective.


Probably the most important and final consideration when buying a mosquito repellent is effectiveness.

Biocidal evaporators have proven to be particularly effective. Although they are only suitable for smaller rooms, they provide very reliable protection against mosquitoes in these rooms.

Mosquito bugs with ultrasonic technology or UV light do not always provide 100% protection, as already mentioned and depending on the given conditions.

A plus of the ultrasonic plug is that other animal species can also be deterred if you set the frequency differently. However, you have to decide on a setting for this.

The plug with UV light works quite universally against different insect species, as they usually react well to light. The problem is, however, that mosquitoes are more attracted to body heat than to light, which is why the mosquito plug does not necessarily prevent mosquitoes from seeking you out.

When buying a mosquito repellent, you should pay attention to the species that the mosquito repellent explicitly targets.

Facts worth knowing about the use of mosquito bugs

How do I use the mosquito repellent correctly?

The mosquito plug is very easy to use. It is simply plugged into a socket and then works independently.

Make sure that the mosquito plug or the active ingredient vial in the case of biocide vaporisers is attached horizontally. Many mosquito plugs also have a practical rotating mechanism that allows you to move the body of the device into the right position.

For mosquito bugs that use ultrasonic waves, you need to choose the right frequency depending on which animals you want to deter. A frequency of 7000 Hz repels mosquitoes.

Always place the mosquito repellent out of reach of children and avoid placing the mosquito repellent near the child’s head if you want to use it in the child’s room.

As a rule, biocide vaporisers should not be used in children’s rooms. If they are used in other rooms for a longer period of time, they must be well ventilated. (Image source: / Free-Photos)

In addition, the mosquito repellent should not be covered or shielded by curtains or other objects, otherwise it cannot develop its full effect.

During the night, it is usually advisable to keep windows and doors closed so that no new animals can enter the room. This applies especially to mosquito repellents with UV light, which would otherwise attract even more insects.

When using mosquito bugs that work with a biocide, it is important that you ventilate thoroughly after use so that the nerve agent evaporates from the air. In general, you should only use the plug when necessary and leave it on for a maximum of 8 hours.

Can the mosquito plug harm my health?

Mosquito bugs that work with high frequencies or UV light are generally safe to use.

With biocide vaporisers, however, the situation is somewhat different, as they vaporise an insecticide that is somewhat more critical from a health point of view.

Many biocide vaporisers use the active ingredient prallethrin, which belongs to the group of not uncontroversial pyrethroids, natural pyrethrum or transfluthrin.

Some of the substances used are suspected to have hormonal activity, which is why a biocide vaporiser should never be used long-term. It is also advisable to ventilate after using the plug so that the amount of chemical insecticide in the air you breathe can be reduced again.

For healthy adults, the released neurotoxin is basically not a danger. However, small children, whose bodies are not yet able to process toxic substances so well and effectively, as well as pregnant women and allergy sufferers should not stay in rooms with biocide vaporisers for a longer period of time to be on the safe side.

Can I use the mosquito repellent in a child’s room?

Since biocide vaporisers enrich the air we breathe with a neurotoxin, they should not be used in rooms where children spend long periods of time or even sleep, as just described.

You can safely use an ultrasonic mosquito plug or a plug with UV light in a child’s room. However, make sure that the mosquito plug – especially if it is an electric plug with UV light – is plugged into a socket out of the child’s reach.

Is the mosquito repellent poisonous for pets?

Mosquito bugs are basically also suitable for households with pets.

Dogs or cats are not endangered by the mosquito repellent. You can also use biocide vaporisers without hesitation.

However, if you have an aquarium, it is better to use an ultrasonic mosquito plug or a plug with UV light.

The chemical agents used are toxic to cold-blooded animals. Cold-blooded animals include all fish, amphibians, reptiles and invertebrates as well as insects, against which the effect of the biocide vaporiser is directed.

Therefore, avoid mosquito vaporisers that work with insecticides, or air thoroughly after use and make sure that you do not place the mosquito vaporiser near the aquarium or terrarium.

Then there is no risk to your animals even when using a biocide vaporiser.

Can I use the mosquito repellent on holiday?

You can take the mosquito plug with you on your travels without any problems and also use it abroad.

Mosquito bugs are even highly recommended in some regions and countries with high mosquito populations.

However, not all insecticides are suitable for controlling tropical mosquito species and insects, which is why you should pay attention to which animals your mosquito plug is designed for. Every manufacturer provides information on this.

Liquid biocide vaporisers can also be taken on flights in hand luggage without any problems because the vials do not hold more than 100 ml – usually less than 40 ml.

Note that in many countries an adapter is required to connect the mosquito plug to the socket or power connection.

How do I dispose of the mosquito plug properly?

Most mosquito plugs can be refilled and usually used for several summers. Therefore, you do not have to throw away half-full bottles or plates for the biocide vaporiser when the summer is over.

If you want to get rid of the insecticide for good, it should be disposed of as hazardous waste. You can simply take the active ingredient and mosquito repellent to the recycling centre.

Under no circumstances should insecticides be disposed of in the toilet, as this would pollute the sewage treatment plants and the microorganisms responsible for cleaning.

How can I additionally protect myself against mosquitoes?

In addition to using a mosquito plug, it makes sense to seal the windows with fly or mosquito screens. This prevents mosquitoes from entering the room in the first place.

In acute cases, it is advisable to apply a mosquito spray that keeps mosquitoes away from the body due to its smell. When spraying, make sure that you really get all parts of your body so that you are not bitten by mosquitoes.

If you are outdoors, a mosquito repellent will not help. In addition to using a mosquito repellent, you can make sure that you wear light-coloured clothing and no perfumes, and that you wear long clothing, especially in the evening.
