Especially on summer evenings, when we open windows to let cooler air into the house, this is a problem. The Gardigo flying insect killer 25 sqm attracts insects with UV light. They die quickly and painlessly at the integrated high-voltage grid. In the bottom of the device is a collection container, which can be easily removed for emptying. The grid can be cleaned with the brush provided.About 1 - 1.5 hours before you use a room at dusk, you should put the device into operation. Without the distraction of human odors and lighting, insects will find their way into the light more quickly. Don't forget to close the windows. After all, you don't want to attract more insects. Once you are using the room, place the lamp outside the room, such as in the hallway. This way, further insects will not be attracted into the room but into the trap.
