Everything about insect screens.

What are the differences between discount fly screens and branded products?
Before choosing new fly screens, you should consider their intended use. For homeowners in particular, it’s important that the insect screen lasts as long as possible. The price can often provide an indication of the expected quality and durability. A plastic insect screen with corner connectors purchased at a discount store or hardware store will likely not last as long as a DIN-certified brand-name product from a specialist retailer.
What features are important to consider when choosing a fly screen?
When choosing a fly screen, you should consider the following aspects: The insect-proof mesh should allow good air and light penetration. A mesh size of approximately 1.4 x 1.4 mm with an openness of 60% has proven optimal. The mesh should have a tensile strength of at least 30 kg, which is sufficient for normal requirements. For households with pets, a more robust fabric such as polyester is recommended. To repel rodents, stainless steel mesh is a good option. The fly screen should also be easy to clean, as indicated by a smooth surface. A simple tactile test with your hand can be helpful in this regard.
What is the best way to attach fly screens?
The optimal mounting method for fly screens depends on the specific installation situation and individual needs. Fly screens can be installed in a variety of ways, including gluing, drilling, or hanging. The choice of method should consider the nature of the window frame or door, as well as preferences regarding installation and subsequent useThe optimal mounting method for fly screens depends on the specific installation situation and individual needs.

How do the prices for fly screens in hardware stores differ from those at specialist retailers?
The decision between a cheap fly screen from a hardware store and a brand-name insect screen from a professional depends on several considerations. A key factor is the available budget. With a limited budget, high-quality solutions are often unattainable. Generally speaking, the less you spend, the lower the quality. At hardware stores, you can find simple, self-adhesive fly screens for less than CHF 10.00. However, a high-quality tension frame from a specialist retailer starts at CHF 180.00. The advantage here is the durability and the possibility of regular cleaning. This leads to the next consideration when making a purchase decision. You can also get higher-quality fabric from a specialist retailer.
Why should owners invest in high-quality fly screens?
For short-term rentals, an inexpensive fly screen from a hardware store may be sufficient. However, those seeking long-term protection in their own home should invest in quality products like those from Neher. These not only offer a longer lifespan but are also custom-made for windows and doors. This guarantees a perfect fit and seal, effectively keeping insects out.

What can you do about mosquitoes in your room?
We don’t recommend chemical products like insect sprays for mosquitoes in your room, as these aren’t a long-term solution and are very time-consuming. After using the spray, you need to let the product work in the room for about 30 minutes and then ventilate it for about 20 minutes. Therefore, we recommend using insect screens instead. Mosquito screens from hardware stores are not recommended for this. Manufacturers like Neher offer high-quality fly screens that are more reliable and durable.
Why should I get a fly screen?
Insect screens for your windows are a smart choice for several reasons. If you want to ventilate your rooms, you no longer have to worry about insects like mosquitoes, flies, or wasps getting in. High-quality fly screens offer an effective barrier against these annoying insects. Compared to using insect sprays, insect protection solutions are a better alternative. Not only can insect sprays smell unpleasant, but they also often contain harmful chemicals. Neher mosquito protection products offer an environmentally friendly approach to keeping insects out without endangering your health. In addition, we offer various types of meshes, including those that can prevent pollen penetration. This is especially beneficial for people with allergies, as you can ventilate your home without risking allergic reactions. Our insect protection solutions thus create a pleasant and insect-free environment in your home.

Which types of insects are particularly annoying or dangerous in Switzerland?
In Switzerland, there are various insect species that can be perceived as annoying or potentially dangerous. Here are some examples:
- Mosquitoes: In many regions of Switzerland, mosquitoes, especially the common mosquito (Culex pipiens), are annoying. They can cause itching and local reactions to bites. In some areas, there are also mosquito species that can transmit diseases such as West Nile virus, although this is rare.
- Ticks: Ticks are widespread in Switzerland and can transmit dangerous diseases such as Lyme disease and tick-borne encephalitis (TBE). It is important to protect yourself from tick bites and to check for tick bites regularly.
- Bees and wasps: Bees and wasps are generally not dangerous, but they can cause painful bites and can be life-threatening for people with allergies. Horseflies: Horseflies are large, flying insects that can cause painful stings.
- Ants: In some cases, ants can be a nuisance in homes and gardens.
- Flies: Flies can be a nuisance in summer, especially near food.
It is important to note that the perception of insects as annoying or dangerous can vary from person to person, and the insect species mentioned are not necessarily a problem for everyone in Switzerland. Insect protection may vary depending on region and personal preference, but basic precautions such as using fly screens, wearing insect repellent, wearing protective clothing, and avoiding insect bites in prone areas are advisable.
Do Neher fly screens need to be maintained to maintain their functionality?
We recommend cleaning the mesh occasionally, as this can extend the lifespan of the fly screens. Additionally, owners of pleated blinds should always retract the pleated blinds when not in use to protect them from extreme weather conditions. These are simple steps to ensure your Neher insect screens remain in optimal condition.
What is the best fly screen mesh in the world?
The best fly screen mesh in the world is undoubtedly “Transpatec” from Neher. With its unobtrusive design, increased transparency of an impressive 80%, sophisticated materials, low maintenance, energy efficiency, and environmentally friendly manufacturing processes, Transpatec offers a unique combination of properties that sets it apart from conventional products. It was developed through years of research and is patented. Transpatec outperforms other alternative meshes on the market, which are often made of fine fiberglass material and are inferior in tear resistance and durability. Therefore, Transpatec is the outstanding choice for insect screen mesh and is sold exclusively in conjunction with insect screens from the Neher system.
Which fly screen is the least visible?
The Neher Transpatec fabric is one of the least visible fly screens on the market. It features an anthracite-colored surface and a particularly fine mesh size of 1.27 x 1.34 mm. The projected thread thickness is only 0.13/0.15 mm, while the projected open area is 80%. The air permeability is specified as 3.2 m/s at a differential pressure of 0.12 mbar.
The fabric was developed through many years of research by Neher. The Transpatec thread is made of a new high-performance yarn that is extremely tear-resistant and weather-resistant despite its thin thickness of just 0.13 mm. This is achieved thanks to the so-called “FX6 factor,” a special additive added during yarn production to increase robustness. Transpatec uses an innovative weaving technique with a binding thread only 0.06 mm thick to ensure high mesh strength and a uniform fabric structure. A special process fills the gaps and firmly welds the threads at the intersection point, further improving stability and homogeneity.
What to do if mosquitoes come into the room?
If mosquitoes have gotten into your room, there are some practical methods to get rid of them quickly:
- Fly swatter: A quick and effective way to get rid of mosquitoes is to use a fly swatter.
- Electric insect killers: These devices attract mosquitoes with light and then kill them with electric shocks. They are particularly suitable for use overnight.
- Insect spray: Special indoor insect sprays can kill mosquitoes quickly. Make sure the spray is suitable for use in enclosed spaces and follow the instructions for safe use.
- Create a draft: Sometimes it can help to briefly ventilate the room vigorously. The draft can carry the mosquitoes outside.
- Use fans: A running fan can effectively drive away mosquitoes, as they have difficulty fighting against the airflow.
- Chemical-free traps: There are traps that do not require chemicals and capture mosquitoes using light and a gentle suction.
Can you ventilate properly with fly screens?
Fly screens are generally designed to prevent insects from entering while still allowing adequate ventilation. Special care is taken during the production of fly screens to ensure they do not significantly impair air circulation. Despite their fine mesh, most models offer sufficient air permeability to ensure effective air exchange. Thus, with fly screens installed, rooms can be effectively ventilated.
