Lidl door fly screen: keep mosquitoes out for €4.99

In France, the arrival of warmer weather is often accompanied by pests that disrupt evenings, meals and the airing of homes.

Published on 11 June 2025, this article looks at a Lidl door fly screen sold by the retail chain. Designed for doorways leading to a balcony, terrace or garden, this accessory is intended to allow air to circulate while forming a physical barrier against mosquitoes and other flying insects.

A fabric barrier for keeping doors open

As temperatures rise, opening patio doors is often necessary to air rooms. However, doing so can also make it easier for mosquitoes to get inside, as they are attracted by warmth, body odours and light within the home.

Lidl sells a door fly screen that attaches to the door frame. Its design is straightforward: two fabric panels cover the doorway and meet in the middle. A magnetic fastening allows them to separate when someone walks through, before automatically closing again afterwards.

“The fly screen should make it possible to keep a door open for ventilation without giving mosquitoes unrestricted access.”

This arrangement can be useful when your hands are full of shopping bags, during repeated trips to and from a terrace, or when a pet regularly moves between indoors and outdoors. It also removes the need to handle a zip or hold one panel open.

Rather than releasing insecticide or a scented repellent, this solution works as a physical barrier. Its effectiveness depends on the fly screen being fitted correctly and its sides remaining securely attached to the door frame.

Lidl door fly screen priced at €4.99

According to the information provided in the publication, this Lidl product is listed at €4.99 on the retailer’s website. It consists of two panels and can cover an opening up to 100 centimetres wide and 220 centimetres high.

These measurements are intended in particular for doors opening onto a balcony, garden or terrace. Before buying, it is still advisable to measure the width and height of the frame, as a fly screen that is too small may leave gaps at the sides.

• Maximum stated width: 100 centimetres;
• Maximum stated height: 220 centimetres;
• Magnetic centre fastening;
• Supplied with hook-and-loop fastening strips;
• Available colours: bright white or anthracite.

The stated installation method uses hook-and-loop strips that are stuck around the frame. The fly screen is then attached to these strips. The source says that no tools are required and suggests that it can be fitted in under ten minutes.

However, how securely it stays in place will depend on the cleanliness and type of surface. Adhesion may be poorer on a dusty, damp or uneven frame. Checking the frame before fitting also helps to ensure that the magnets align properly in the centre.

Highlighted customer reviews

The page refers to a rating of 3.9 out of 5 stars for this item. Some customers praise the device’s price and usefulness. One considers it an “Inexpensive item that is effective as a barrier against mosquitoes and other insects”. Another writes: “The best I have had so far. I recommend it”.

These comments reflect individual experiences. They do not replace checking whether the product is suitable for the door in question, nor regularly inspecting the condition of the fastenings. A tear, a detached edge or a gap beneath the fabric is enough to reduce the barrier effect.

The mosquito situation in France

In France, mosquitoes are more than simply a summer nuisance. The tiger mosquito is now established in many departments. Identifiable by its black-and-white stripes, it can bite during the day, contrary to the belief that mosquitoes only emerge at dusk.

French health authorities mainly recommend reducing breeding sites around homes. Mosquitoes need standing water to reproduce. A door fly screen can limit their entry into the home, while removing small collections of water tackles the problem outdoors, close to the areas where they develop.

“Blocking insects from entering and removing standing water are two complementary measures around a home.”

A few steps can reduce the conditions that favour mosquitoes near a house or flat:

• Empty saucers beneath flower pots regularly;
• Store away or turn over objects that can collect rainwater;
• Cover water butts when they are in use;
• Check gutters and small containers left on a balcony;
• Fit fly screens to the openings used most often.

A solution for frequent movement through doorways

A door fly screen does not necessarily replace a fixed window fly screen. The two products serve different purposes. The first is intended for frequent movement outdoors and back inside, whereas the second is better suited to an opening left open without anyone needing to pass through it.

The choice also depends on the layout of the home. In a flat with a balcony, patio doors may be the main route for insects when evening temperatures remain high. In a house, several openings may require separate protection.

To keep the magnetic fastening working properly, it is best to remove dust and small pieces of debris that may stick to the fabric. It is also important to make sure both panels hang at the same height. If they do not close fully, a gap may remain in the middle-the very place where insects can get through.
