Table of contents
What types of insect protection are available?
In general, there are three different ways insect protection works: mechanical, chemical and physical barriers. Each has its own advantages and disadvantages.
Mechanical protection
This includes all barriers that physically prevent insects from getting inside. These include classic fly screens for windows and doors, mosquito nets for beds or tents, and special clothing made from tightly woven fabric. The main advantage is that they are completely free of chemicals. They are ideal for allergy sufferers, households with young children and long-term protection in bedrooms and living areas.
Chemical protection
This method repels or kills insects using active ingredients. It includes mosquito sprays (repellents) for the skin, plug-in vapourisers, mosquito candles and mosquito coils. The effect is often highly reliable and covers a wide area, as with a plug-in mosquito repellent. However, you must follow the instructions for use, especially in sensitive environments.
Take care with chemical products: Keep all chemical insect repellents out of the reach of children and pets. Do not apply skin repellents to large wounds or mucous membranes. Air rooms thoroughly after using a vapouriser.
Physical and biological protection
This category uses natural predators or attractants. UV light traps attract insects and kill them with an electric shock. Glue traps catch them without using poison. is an example of a professional glue board trap. Biological methods include bat boxes and the use of nematodes in the garden. These solutions are environmentally friendly, but are often more targeted and cover a smaller area.
How do I find the right product?
Before you buy, you should answer four questions. They will lead you directly to the best solution for your situation.
1. Where will it be used?
Is the protection intended for indoor spaces, a patio seating area or outdoor adventures such as camping? Vapourisers and screens are ideal for enclosed rooms. Outdoors in a small area, such as around a garden table, lanterns or coils can help. For personal freedom of movement while hiking, sprays or special clothing are the first choice.
2. Which insects should it protect against?
Mosquitoes, flies, wasps or horseflies? Not every product works equally well against all of them. UV traps are effective against nocturnal flying insects. Different active ingredients are often needed for biting mosquitoes than for troublesome fruit flies. Read the product description carefully.
3. How long is protection needed?
A mosquito candle is sufficient for a one-off barbecue. For continuous protection in the bedroom over several weeks, a long-lasting vapouriser or a permanently installed screen is the better investment. Maintenance also plays a role here: glue traps need to be replaced regularly, while screens need cleaning.
Tip for layered protection: Combine different methods for maximum effectiveness. For example, install fly screens as basic protection and use a vapouriser as well on evenings when mosquitoes are particularly active. This gives you protection on every level.
4. Who will use the protection?
Are there children, pets, allergy sufferers or people with asthma in your household? In this case, you should use chemical products with caution and favour mechanical or physical barriers instead. There are also specially labelled sensitive products with milder active ingredients.

Solar-powered solutions for the garden
Self-sufficient and eco-friendly: solar lamps with integrated insect protection, often using a special fragrance, are perfect for the patio or a seating area in the garden. They charge during the day and provide light and protection in the evening. A product such as is a good choice here. Its effect is limited to the immediate area around the lamp, but that is more than sufficient for sociable evenings outdoors.
Professional glue traps

They attract insects and trap them hygienically on an adhesive film, entirely without poison and safe for people and animals.

Applications at a glance
Home and apartment
Here, mechanical protection with made-to-measure fly screens is the most long-lasting and gentle solution. For extra comfort on muggy summer evenings, complement it with an electric vaporizer in the rooms you use most. Do not forget basement windows and ventilation shafts as possible entry points.
Balcony and patio
They create a protected zone. In addition to solar-powered lanterns, special scented candles or oils containing citronella or neem can help. A canopy or pavilion with integrated insect screens creates an almost mosquito-proof outdoor room.
Leisure and travel
When camping, hiking or fishing, you are exposed to insects. Pack a skin-friendly repellent, a lightweight mosquito net for the tent entrance and long, light-coloured clothing. A small battery-operated UV lamp can be useful on the camping table.
Care and maintenance
To keep your insect protection effective for a long time, it requires some care. Clean fly screens regularly with water and mild washing-up liquid to remove dust and pollen. Replace cartridges or liquids in vaporizers in good time, even if there is still some left – their effectiveness often decreases. Empty glue or electric traps as soon as they are full. Store chemical repellents in a cool, dark place to keep the active ingredients stable.
Safety instructions
Safety comes first. Always place vaporizers in an unobstructed position, away from flammable materials and never behind curtains or furniture. Do not use electrical devices outdoors unless they are explicitly designed for this purpose (check the IP rating). When using skin repellents, first test the product on a small area to rule out intolerances. Always follow the manufacturer's instructions regarding the maximum application time.

Frequently Asked Questions
- Which insect repellent is suitable for people with allergies?
- For people with allergies, mechanical barriers such as fly screens or mosquito nets are the first choice because they do not use chemicals. UV lamps with glue traps are also a good option. Avoid vaporizers containing pyrethroids if you are sensitive to chemical substances.
- How long does the effect of a mosquito plug-in repellent last?
- How long a mosquito plug-in repellent lasts depends on the cartridge or liquid. Some provide protection for up to 45 nights, while others last for an entire season. Check the specified room size and replace the cartridge in good time to maintain its effectiveness.
- Do solar-powered insect repellents work even with little sunlight?
- Yes, modern solar-powered devices have rechargeable batteries that store solar energy. Even in changeable weather, they usually provide enough power for use at night. However, models with a mains connection or long battery life are recommended as a backup in regions with very little sunshine.
- Can I use insect repellent products for my pets?
- Yes, there are special products for animals. However, never use human repellents or room vaporizers for pets, as many active ingredients are toxic to them. Only use approved animal products such as special sprays or collars, and follow the instructions for use carefully.
- What is the difference between a UV lamp and a vaporizer?
- A UV lamp attracts insects with light and kills them with an electric shock or catches them on a glue sheet. A vaporizer releases a chemical tablet or liquid active ingredient that kills or repels insects in the room. The lamp is chemical-free, while the vaporizer often provides wider coverage.
